hi there neokn! ya lah! truly annoying i say, though it cant be helped if its in their nature. thing is, i have a neighbour, bro kenyeo, who has a black cap twice the size of my larger one, and it leaves all inverts alone. well, hopefully this move lets me keep the shrimps i like! bros roger and glenn, shall pm you shortly ya. for the moment, pls consider the black cap reserved, as most pms have been for the black cap. anyone keen on the tunze, pls pm. cheers all! ian

Hi there everyone, I have one Tunze Nano 6025s for slae at $65. Additionally, i am thinking of selling my male black cap gramma (at present i have a pair), as it eats s e x y shrimps and i would very much like to keep some of them. So take note that should you buy my black cap, you wont be able to keep s e x y shrimps and other small shrimps. normal cleaner, blood, and camel shrimps however, are fine though as they are too big to fit into its mouth. size is about 2 to 2 and a half inches. Please let me know if youre keen in advance, as i still have to catch the fella. pls pm if interested. thank you! ian

Hi there bro uws, thanks! though if you look closely, theres algae aplenty!!! hahahh. which i attribute to flow conditions, because despite my two return outlets randomized by hydor flos and two tunze nano 6055s in a 70L display tank, i still have dead spots, which i guess is to be expected in a crammed nano.. anyhows i think the distance you keep your sps from your lights depends on the mix and number of tubes youre running. the more tubes you have, the deeper you can place your sps. my tank's height is just 1.2 ft though, so not very high at all, which is why im able to keep my sps even at the bottom. are you running just the 2 x ATi Blue Plus and 1 x Actinic? or is your main lighting an MH with T5s as supplement? because white light is far more crucial to growth and long term health than the blue or more violet spectrumed tubes. id certainly recommend the ATi Aquablue Spezial. cheers, ian

hi there guys, just a side view shot of my little sps reef: i'm running 4x 39w (1 x ATi Aquablue Spezial, 1 x korallen-Zucht Coral Light, & 2 x ATi Blue Plus) cheers, ian

hi there bro harold! pls do let me know if the buyer backs out ya. i'm willing to purchase both the eagle eyes and the rics in a jiffy! hahah if no longer available, its cool too ya! all the same, upz for your sale.

thanks for that wonderful bit of info bro gouldian!! i just learned something new!

hi there bros! hhahhahaa. sorry for the late post, but selmat hari raya all the same ya!!!!

hi there everyone, thank you for your pms. both colonies have been sold, so thread closed. cheers, ian

also, please note both pieces are wild. thanks, ian

hi there everyone, thank you for your pms. as of now, i would like to only consider those who are keen on both pieces, and who are confident of their ability or system's ability to maintain these two colonies of SPS as i didnt buy them with the intent of selling. so, those keen on both pieces, pls do let me know if youre able to view today. viewing does not constitute any committment on your part to purchase. thank you. ian

Hi there everyone, i have two colonies of SPS that i'm unable to fit into my present rockscape as am running out of space. all were bought at $25 each during the last two shipments, and the selling price is the same. 1) Large colony of Blue Staghorn. 2) Pink Milli with Blue Tips- Tabling form (this colony has lost its bright pink somewhat as its sitting on my BB, but the blue tips are very blue. will require high light to manifest both its original bright pink and strong blue colours) picture of the staghorn: Please pm if you are interested. thanks. ian

ya bro gouldian, you should join this rocking bunch of reefers for their next gathering. really quite cool!

Thread Closed. Thank you for viewing.

hi there bro klim, perhaps i can share with you some of my personal experience. my present display tank holds about 70 odd litres, and because i planned it as a full sps system, i had two return outlets into the display pre-drilled, and use two 4000L/Hr pumps on each return. this achieved an incredible amount of flow in my display, but i also realized that it affected skimming, which nowadays, seems to play an increasing role in our modern tank's filtration. in discussions with some fellow reefers, like bro madmac, i realized that this compromised skimming efficiency because water was overflowing into my sump and being returned to my display faster than my skimmer could effectively skim. this meant that alot of the nutrient laden water coming down my overflow was being returned to my display, effectively voiding the principle of having an overflow in the first place. likewise, skimmers work best when nutrient laden water is delivered to its chamber for mixing, as it helps sustain a stable foam head. anyhows, i soon realized too that my idea of achieving all my flow needs through my two returns wasnt working out. (keep it mind that this is a really small tank too) what happens is that return outlets project a very focused stream of water, that coupled with a strong return pump, delivers a very strong, focused and constant stream of water, and this generally isnt very beneficial for corals in terms of providing for their flow needs. most corals, LPS, SPS, whatever, will soon perish if blasted with flow, so with a strong return outlet, you'd have to direct it away from you corals so that flow is achieve indirectly by pushing open water or reflecting off glass panels. this is good, but it also in the end reduces the flow and how widespread it is throughout your tank, and eventually, youll decide to add extra wavemakers into the tank. when i chimed in to reply to your posted query, my simple point was perhaps you could consider using a less powerful return pump, and try to match it to your skimmer's flow rate (with a 2,500L/hr feed rate for your skimmer, an eheim 1262 sounds like a well-match return pump), you can achieve maximum skimming efficiency- then add a couple of good wavemakers into your display. wattage wise, the tunzes are fantastic. in any case, with good husbandry, i think your tank will thrive, independent of the size of your return pump. just take note to measure the maximum flow rate your overflow can handle if you decide to adopt a very high flow rate return pump, as you dont want the situation where more water goes up than comes down. all the best bro! cheers, ian ps: you can check out the reefkeeping, reefpark or zeovit forums TOTM sections for inspiration too ya, as that can give you an indicatation of the return pumps being used in successful systems.

bro reeftask, sorry, but pls consider reading my post again. i am trying to recommend that he choose a return pump that has a similar flow rate to the flow rate at which his skimmer's feed pump is rated. the principle of which is entirely separate. and bro, do note that the flow rating for different brands of pumps mean different things- alot of brands over-estimate their flow rates. an eheim, aquabee or even better, deltec or red dragon pump will not suffer quite as much from head loss as a generic hailea or rio pump. and bro, an Eheim 1260 pump, rated at 2,400L/hr, will deliver at least 1000L/hr flow rate at a height of 2m, whereas a rio pump may do so, only to splutter and fail over a short time. pressure-rated versus non-pressure rated.

hi there bro reeftask, a pressure-rated pump will specify on its packaging, how much flow pressure it will lose over a given height. similarly, no matter how strong a return pump you employ, you will realise that you will still need to supplement your display tank flow rates, because the nature of a return outlet is that it provides a single direction and constant flow pattern, as opposed to a diffused and randomized flow pattern. similarly, the rationale of skimming the thinnest layer of water with your overflow by matching the flow rates from the return pump to your skimmer's feed rate is to ensure that the overflow delivers water that is most concentrated with organics to your skimmer. having an oversized return pump, with unnecessarily strong flow rates will not help your system, because the essence of the sump tank is to filtrate the water, and if water is being cycled from your tank to sump then back to tank faster than your skimmer or other filtration equipment can handle, then in essence, youre just returning some portion of overflow water back into your display. an eheim 1260 or 1262 will still achieve 1,500L/hr with a height pressure of 2m, whilst an aquabee 5000 will achieve 3,000L/hr with a 2m head height, both of which are wattage efficient pumps for the flow rates they deliver. anyhows, just my two cents ya. cheers, ian

hi there bro klim, with regards to your need for flow within the display tank, i do feel that you will still need separate wavemakers within your display to provide dispersed and randomized flow, for example, with Tunzes or Vortechs. for a return pump, you should aim to have the return flow rate roughly match the feed rate of your skimmer. so if you have a skimmer powered by a 2000L/hr pump, you can do with a 2000 to 3000L/hr pump for your return. this ensures that your overflow skims the topper-most layer of organic material and brings this to your skimmer for effective skimming. having too high an overturn rate may not necessarily help with filtration or skimming, and may also overly tax your overflow going-down pipes to their capacity. are your return and overflow pipes adjustable with a ball valve? similarly, how many return outlets do you have at the moment? a 6000L/hr flow rate exiting a single return pipe may provide too much flow for most corals, even sps, in a small area near the pipe, as the flow is constant and focused, as opposed to diffused. for a 5000L/hr pump, id definitely recommend the Red dragon bro jervis is selling; other brands id recommend from personal experience are the aquabees and eheims. cheers, ian

Hi there everyone, i have a Korallin Calcium Reactor, model C1502, for sale, with an attached RM Hang-On Second Chamber, both filled with Rowalith Media, together with two CO2 cylinders. One of the CO2 cylinders is a 3L Singapore Industries Certified cylinder that may be exchanged one-for-one at many of the top-up LFS like Nature Aquarium, thus preventing the situation where you have to visit the LFS twice- once to leave the cylinder for top-up, and another to pick up the refilled cylinder. The other cylinder is a 2L cylinder used as a backup for times when i am unable to go to the LFS to make the exchange. The CO2 cylinder comes with a good two-stage regulator. All equipment have been in use for about 1 and a half years to good effect in my full SPS system, and are in good working condition. This is a picture of my tank as of last week, to illustrate the reactor's capability to maintain good calcium and alkalinity levels: I am keen to sell the whole set at $450, which includes all of the above: 1) the Calcium Reactor 2) the second chamber 3) one 3L CO2 cylinder 4) one 2L CO2 cylinder 5) one two-stage regulator 6) Rowalith Calcium Reactor Media 7) Hose and Pipings 8) Feed Pump with attached Tee-Off for the Reactor Additionally, i shall explain the full workings of the Reactor to the would be buyer. Reason for selling is that i am planning to install a large external refugium to better buffer my night time ph levels in my system, and that will take up a great area underneath my room table, so i'm trying to make away with as much of my equipment as possible, and utilize an automated 2-part dosing system. If anyone is keen, pls pm me. Thank you for viewing! Best Regards, Ian

hi there bro clowny lover, thank you for your offer. sorry for the delay, but ive passed the colony to a group of friends for fragging. thread closed. thank you

hi there bro reeftask, that algae looks so cute- its almost like little green starfishes gathered together, looking at the picture. cool!

Hi there everyone, haha! i have an exquisite SPS colony up for swop (well, maybe not so exquisite- you be the judge!) i am looking for a red/pink acropora millepora or prostrata colony in exchange, in a particular shape (shown below), so if anyone's keen pls let me know. the colony up for swop (pardon the lousy pic from my old casio exilim- body is white, with a slight green tinge, whilst the corallites and tip is a deep purple in colour- polyps are green- size is about 7 inches in diameter) the piece i am looking for should look like this in its shape: 1) 2) please do contact me via pm with a photo if possible, should you have a pink/red milli/prostrata in this shape and size. thank you very much!!! ian

hi there jasment, i'm more inclined to bro tineng's view, and would be keen to know the basis of your suggestion. it'd be interesting to learn more bout the success of maintaining discernable nitrates within an sps sytem. bro bhteo, do note that nobody really knows everything there is, to the care of SPS corals, or any corals for that matter. we are only guided by practices that have yielded success, plus the knowledge established by the reefing and scientific community. its great to hear you've upp-ed the flow levels in your system, but do note that sps corals do not take well to being directly blasted with constant laminar flows, as it will likely inhibit the extension of its polyps, and cause its tissue to slough off. itd be best if the powerheads are pointed to push water above the colonies, as that will move the water surrounding that area as well. you've not told us how youre maintaining ca, alk and mg levels, but if youre observing growth on your pieces, well done ya! its a great first step. now, to just keep the parameters stable. cheers, ian

hi there guys! i didnt manage to go to any of the shipments last night in the end la. irwana changed timing and i was still stuck in the office. ah well.. maybe tonight might be better. as for sewing, of course i can sew la- all my fish nets, filter bags for rowa, all hand-sewn one! haahahhh... just teasing la. but seriously, no moolah can still come see see and minum kopi together right? then if theres something superb, we can always share and frag. cheers, ian

alamak! baju kurong i sew for you cheap cheap la. haahhahahaha tonight must go la- two shipments in close vicinity you know!

hi there guys, anyone planning to go by irwana for the shipment tomm night at 8? cheers, ian
