Skimz Calcium Reactor CM113 DUO - $220 Skimz Recirculating Biopellet Reactor RR113 - $190 Deltec Skimmer SC1456 - $450 The above are still available. The skimmer is a Deltec SC1456, DC pump, very quiet, and I suspect, the only one sold in Singapore. I could be wrong but I think Seet has not brought in anymore. Still under warranty. No more reservations, got played out by TWO pilots already. Ng@****4393 and Tan@****0882.

Warranty within, stamped with today's date. Deltec skimmer was in use for 3 or 4 months, still under local warranty. You either buy titanium coil off Fishstreet/ Aliexpress and I'll provide contact to assemble or get Derrick to sell you his blue resined copper coil and his welding skill. Pictures later. Kindly contact me at nine, four, five, double zero, double three, nine.

Sold.

As above for $250. I am not sure but it could be a 1/2 hp, about two years old. Just removed, going to back flush as soon as I stop being lazy. Please contact 945-double zero-double three-9

You mean the other way around (see Zeovit bible)? This is a compilation of how much Zeostart3 the gurus are dosing. Cyano gets a huge kickstart and thrives on carbon source (Biopellet, Vinegar, Vodka, Zeostart3, NoPox, etc). Especially if the tank started on dead sterile unhealthy rockwork, and carbon source is added without being taken up by quick multiplying heterotrophic bacteria (Zeobac, Polyplab Genesis, Ultrabio, etc).

I have noticed KH and PO4 is linked to SPS PE extension, not just KH alone. I had PO4 at 0.06ppm to 0.1ppm, my KH needs to be above 8.5 for better PE, perhaps even higher but I've never gone there. Now with PO4 around 0 - 0.02ppm, it needs to be below 8. I am at 7.8dKH, perhaps the 7 - 7.5dKH range but I am lazy. I may be completely wrong though.

Let me hazard a guess, eggs probably from snails, unlikely but could be from fishes. Have you noticed your snails sucking faces doing the hanky panky?

I can't twerk in front of my tank, I have bad back. My kids would probably seek medical help if they see daddy twerking. I know you meant tweak, too much T & A swimming inside your head bro. @Threadstarter You listed all four carbon dosing methods (missing out on biopellets only). Dosing organic carbon carries inherent risks, a lot of manual labour (exception of biopellets), a lot of experience understanding what your tank is telling you. I have not heard of anyone carbon dosing, NOT encountering cyanobacteria, strange tough brown hairy algae, and myraids of unexplained oddities. Only the severity varies. Have you research old school all natural methods?

5 months old tubes are 2 Coral+, 1 Purple+, 3 Blue+. New unused, original variable DC adapter for the fans from ATI (I used my own) New unused, original hanging kit from ATI (I used my old Radion hanging kit) 4 tubes of new, unused Aquablue Special. Ghetto-wrapped. Items bought on 12th Nov 2014 Started using on 25th Dec 2014 Here is the amazing thing about Janet Yeong @ Aquamarin, the warranty is transferable. Then again, it's ATI, as if you need warranty.

Asking $550 4 feet Six tubes 5 months old Includes all six 5 months old tubes and 4 new Aquablue Specials tubes I will post pictures when I have time tonight.

MIX Mix these liter by liter in a clean saltmix pail. Add the required amount into 1 Liter, grab the pail and twirl 10 seconds, rest, twirl again, the solution should clear in 3 minutes. If you add the entired amount into 5 Liters, you will have a hard time dissolving them manually. Calcium • Calcium Chloride Dihydrate FM Balling Light recommends 400 grams into 1 Liter Randy recommends between 66 grams to 660 grams per Liter 0.3668 grams into 100 Liters raises 1 ppm of Ca. • Anhydrous Calcium Chloride 66.6 grams into 1 Liter to have no precipitates. 0.2769 grams into 100 Liters raises Ca by 1ppm. If you have precipitation, you won't get 0.2769 grams raising 1 ppm in 100 Liters, and get floaty white flakes in display tank. Anhydrous Calcium Chloride looks wet when exposed to air and mixes hot unlike Dihydrate which already has 2 moles of water. Alkalinity • Sodium Bicarbonate 100 grams per 1 Liter with room temperature rodi water (from above link) 0.1679 grams into 100 Liters yeilds 1 ppm of CaCO3 (or 0.056 dkh). • Sodium Carbonate 100 grams per 1 Liter with room temperature rodi water. 0.10589 grams into 100 Liters yeilds 1ppm of CaCO3 (or 0.056 dkh). You should get clear solution if Sodium Bicarbonate is mixed liter by liter. If you mix with hot water, you get half pass six Sodium don't-know-what-Carbonate as the water cools before all the Bicarbonate bits loses CO2 to become Carbonate. . Properly heated Arm and Hammer baking soda from some NTUC at 200°C in oven for 1+ hour yeilds Sodium Carbonate. Carbonate raises pH more than Bicarbonate, more concentrated, and uses less solution per ppm. Sodium Bicarbonate looks more talcum powdery, Sodium Carbonate looks more sugar-like.

Liew™, I changed underwear.

Perhaps it's the glass of your tank? Cloudiness of water? Anyhow, here's a quick test. http://colorvisiontesting.com/ishihara.htm PS. I can't see anything except 16.

All sold.

Thank you for so many interests. I apologise if I can't get back to all so quickly. However, I appreciate a deposit to my account if you wish to reserve the Vortechs. I've been 'flown aeroplanes' one too many times. Very uncool to tell somebody else it's sold only to have buyer withdraw a week later.

Only Ecocity sells the Kessil gooseneck. Email or call him and ask for cash on delivery. It'll take at most 2 weeks. I used to mount mine from the ceiling with Radion hanging kits, works perfectly. LEDs are great for LPS. Kessils are great for frags of SPS, no so with colonies (great growth but really bad colour beyond 50% spectrum), it's too much of a point light source. Remember to start with 40% spectrum and 50% intensity.

Bro, I am assuming you are only running DI resins without the RO + carbon + filter part? I used to do that for my nano, the flow through resin should be very very slow. You should be seeing fast drops of water out of the resin, not a flow/ stream. Worse than postrate problems. I used to change at 2ppm of TDS. They exhaust very quickly, about 150 liters worth of clean water if I remember correctly. Really not worth the money replacing them this way.

Sold to a no nonsense steady reefer.

Hi, If you rub your fingers over new reefing equipment, they will come off slightly greasy, it's this plastic greasy thingy that causes overflowing skimmers. Equipments like reactors, skimmers, wavemakers, filters socks/ wools. It is especially noticeable when your water is clean and tank newish. You can test it yourself again, just put in new filter wool and watch the fun and joy. For older stable tanks, it will happen too but they stablise within hours. For every new purchases you plan to immerse into your tank, it is best to soak it in hot water (not boiling, that will weaken rubber seals, but just hot). You should see stubborn bubbles on greasy equipment, soak until the bubbles go away, 48 hours or so. Or you can just rub it with all the love you can muster under the tap. If you have already dump something brand new in without cleaning, you need about 10% tank volume worth of new saltmix next to you as you empty your skimmer cup and replace with new saltmix. Tedious work.

Bought for $589 last year. In used for about 1 year 4 months. I would like $380 for it. Kindly message me at 945, double zero, double three, nine.

Zoe Tay your neighbour? I stay along Shelford Road.

Ah ok, you are downgrading. My heart nearly stopped until I scrolled down.
