isnt doing anything. iam out of ideas and iam ready to give it up. and the werid thing is that things seem to be doing ok in there with the high levels. i have corals and fish and they are ok. so iam thinking that maybe the test is inacurate. but then when i tested the new water it came up 0.
Have you had the water, the water from the tank that is, tested at your LFS
? If not, I would have it tested there along with a tube of the replacement water...just remember to keep the tubes separated or mark them in some way. That is the quickest way to figure out if your tests are accurate.
If the inhabitants have improved with the water changes chances are your nitrate levels aren't as high as you think.
Which test kit are you using and how old is it?
