Water changes with no nitrates???

Should a person perform water changes when all water parameter look good

Yes. The idea of wc is to maintain good water quality. Not when you start to see bad water. Most of the times it's too late then.

Depending on what you have in the tank. Are you testing for the various trace eliments that many corals need for good growth. These things also get .depleted over time and need to be replenished. They are much harder to keep track of, if you are fish only you can probably get away with fewer changes, but nitrates are not the only things are tanks need.

There are more things that you can't or don't test for than than there are things that you can. Water changes are important not only to replenish certain trace elements, but also for the export of other things that build up over time.

Well I thought you want zero nitrates nitrites my ph is 7 .9'the tank is about one month old and has 2 clowns 1 fairy wrasse and one blu hippo tang. All my rock is bleaching but I have not tested calcium levels. Phosphates levels are rather high. How often would you recommend water changes???

Are you using RO/DI water? If you aren't, and the phosphates are coming from your tap water, that could be part of your issues.

well if the phosphates are high you definitely should do a water change. As for how often, it depends on the person, for example I do 15-20% every two weeks, some do 10% weekly. some do 5% biweekly. What do you mean your rock i bleaching?

stl fish spot · 07/10/2011, 12:55 PM

It is turn white, I do have a ro but no di.I know this is kinda off point but can you cure live rock in cold water???I ask because I have 2 5 gallon bucket I am preparing to start my water change with and one has about 10 lbs of live rock I forgot about. I had got it for my sump? Any thoughts?I worry that there could be a ammonia spike if I put this stuff in my sump...
