cedricang Posted April 4, 2010 Share Posted April 4, 2010 Hi Guys/Desi, IMO, water change serve as a very immediate and effective way of nutrient export. The frequency or % change really depends on the feeding regime of individual reef tank. Visual inspection allows a gauge on how much water change is required. Wilson rightly pointed out that regular test on parameter is a good practice to ensure nothing goes out of the range ( especially Kh), i chk my Kh at least once a week. Also try to use reliable salt mix ( especially for sps dominated tank ), savings on some cheaper salt brand may not worth the while. Check out those awesome looking tank from Reefcentral and you will come to a general conclusion - good deligent husbandary work Btw, my beloved convict tang just RIP on me today...was a healthy specimen and seeing it grazing happily just yesterday 2 Quote Treat others the way you wanna be treated...

SRC Member desideria Posted April 5, 2010 Author SRC Member Share Posted April 5, 2010 CEDRIC!! NNOOOOOOOOOOOOOOOOOO...... my condolences... To be honest the PBT you guys saw me buy is also not doing good.. I swear on all that is marine relatedly holy, if this little one goes to heaven, i will not buy any more powders until my water parameters are better. ENOUGH for the time being.. All other fishes doing ok so far. Did nitrate, nitrite, phosphate, Mg, CA, KH testing and everything is good and the results were : Nitrite and Phosphate : 0 MG : 1290mg/L Ca : 420-430ppm KH : 8 DKH ph : 8.4 SG : 1.025 nitrate : 25-50ppm <-- this one is my killer so I'm working on it. Btw, I'm seriously considering getting a RO unit.. my stupid Crystal PRO is crap... I do one water change of about 200L or so and now the reading has climbed back up to 70ppm! And this is buying the slightly more expensive Resin! WTH! I should not have wasted 200 on this unit and gotten a RO in the first place. Damn.... once I get a RO I"m going to sell of this crystal pro to somenoe with a NANO tank as I think it's more suited for someone with lesser water requirements! desi 1 Quote Cheers, Desi Sheldon (TBBT): A little misunderstanding?

SRC Member raydiative Posted April 5, 2010 SRC Member Share Posted April 5, 2010 only alternate week?? i started once a week water change (if not twice) after returning from his place! hopefully can start some SPS growth... besides, parameters testing is also equally important. I change 20% weekly.. think its better for the corals and fishes. while doing regular w/c you can suck up all the detritus at the same time.. (for small nano especially!)

wilsontantw Posted April 5, 2010 Share Posted April 5, 2010 Desi, I'm no expert with fish, but I hear that if you keep the Sg slightly lower, I.e. Hyposalinity, you can help them to reduce their stress. I dunno how true, but somehow it works for some. How abt trying 1.022? Ur parameters look good except for no3. How are some of the sps doing?? If they brown out, I guess u know where to fix. Do u also clean ur skimmer regularly? Especially if u do heavy feeding. A cleaner skimmer neck improves it's efficiency.

SRC Member desideria Posted April 5, 2010 Author SRC Member Share Posted April 5, 2010 Hey siangz, mine is half a feet wider 4 x 2.5 x 2 RB did the calculations for me and my tank volume is (if I remember correctly) 566L and the total volume of the sump is about 120-150L or so.. I can't remember .. so I round it up to 700L la. Anyway, yes, I will not try powders until probably end of the year.... don't want to see another beauty go down because of my foolishness. I just want the rest of my fish to go back to the state before I even tried powders 3 weeks ago. Now my Tangs have all recovered, left the rest of my fishes I see they have spots but they are all still eating and swimming around. The Male anthias scared me and Ketchup when we saw him resting on the sand but then every now and then he'd get up and swim around with his harem of other fish. Then he'd go sit on the sand again.. and then he'd go swim around... Guys, if I go meet you for another LFS outing, please SLAP me if I look gian @ fishes... i only intend to add coral.. NO FISH for the next month or so. lagi like intervention... haiz! and yes, I clean my skimmer cup every 3-4 days. I have had Ming's SPS for about a week or so and it's actuallly GROWING.. I got a birdsnest from her. And today 2 frags of green milli and 1 pink birdsnest also from hijacking bro. See how they do, right now on the plug holder.

m12345y Posted April 5, 2010 Share Posted April 5, 2010 i think you just be a bit more patient.....actually i got a very small YT and PBT from LCK, the same batch as your previous one if i'm not wrong, both are doing fine so far. i also kena white spot a few times in the beginning and lost some fishes. As for your nitrate, not much to be worried since you dont keep SPS, just slowly bring it down, and from online resources, the most reliable/economical way is still a sulfur bead denitrator IMHO.

Damn.... once I get a RO I"m going to sell of this crystal pro to somenoe with a NANO tank as I think it's more suited for someone with lesser water requirements! desi i was adviced against using crystal pro for large water changes as well.. at that time when i was shifting my LS from old tank to my new tank, i was using more than 200l of "filtered" water only to realise that after my 3rd pail of water, i tested the PPM and it was something like 120ppm, way above some of the normal tap water readings. oh well, that was because my old resin was already giving out about 50ppm water before that, and i thought after that large water change i would change the resin.. didnt know that it would shoot up so high... anyway, i'm still using crystal pro for my 2ft.. sometimes i would just get NSW if i pop by iwarna.. but i agree with the rest, should use NSW for large water changes in the longrun.. but of cos if you're getting a RO unit, thats another case which is different altogether 2 Quote My Decomissioned 2ft Cube: (31st March 2011) Carpe Diem~!!!

Moderators thomas_lim Posted April 6, 2010 Moderators Share Posted April 6, 2010 Sorry to poke my nose in this thread. I read abt salinity and water changes. May I suggest using distill water and salt mix. In this case, you can eliminate unwanted bad bacteria from the sea water if any since you are looking into introducing good clean water replacement source. This way, you can also control the salinity as different LFS water had different salinity. Some as are below 1.020 level. Salinity level of 1.021 to 1.023 is good enough for mixed reef. In the ocean, it hardly go beyond this level. The key will be holding the salinity stable and not let it fluctuate too much. As most LFS' salinity level is pretty low as this help to reduce the disease like itch. You will need to acclimatise new fishes bought from LFS properly to prevent "shock" to them. They may not show it on the first few days, but weeks later. Just my 2cts. 2 Quote Tom Link to comment Share on other sites More sharing options...
