changing water?
 
so my nitrites are still very high. and i just did a 30-35 gal water change and they are still very high. im wandering how long i have to wait to do another water change. and is there a limit to how many i can do in a day.

i think 5 days is what i was told. try cleaning your filter 5 days after u do a water change it might help

for some reason i dont think you are right. ive been told by many to change 20% daily before, and not to clean my filters that often. im just wanting to know whats the soonest i can change my water.

how big is your tank? that really makes a difference in how often and how much you should change. but in any situation where poinsoning is possible (such as in your case)- it is preferable that you do the change to save the fish. I had a tank once that I had this problem with- I had to do a 30-35% daily to keep the fish alive. some think frequent water changes slow down the cycle- i didn't care, I just wanted my fish to be alright.

Like Mia said, 30-35% daily won't do any harm, and may indeed be a good thing.

its a 55 gal and i have no fish in it at the moment.

Just curious if you have no fish in the tank, why are you concerned about water changes at all?

tcr03 05-12-2007 04:16 PM

the nitrites are too high. i want to get them down so i can put fish in the tank

I understand that part... do you have a nitrate reading? If they are showing they should take care of the nitrite spike without the need to change water if you have no fish. I wouldn't add fish until the nitrites are 0 and the nitrates are showing a readable amount.
