Is this Statement True?

[Jess7]

I just read this on a webstie:

"At a level of level of 1 ppm or 1 mg/l, fish are under stress, even if they don't appear in acute distress. Levels even lower than that can be fatal if the fish are exposed continuously for several days."

If the Ammonia levels are at .25 for a couple days, it is that bad for them? Meaning you should change the water until levels are at 0 while the tank is cycling?

Levels of what? Ammonia, Nitrite, Nitrate?

Ammonia

Yes, the statement is true. Yes, any amount of ammonia is bad for fish. I think you'd have a tough time keeping the amount of ammonia at zero before the nitrifying bacteria are able do the job on their own, but the best way to control the amount of ammonia in the tank, until you have a good bacterial colony, is to do water changes.

Edit: Also, being careful not to overfeed fish will help keep the ammonia levels in check.

NitrItes will likely spike once your ammonia starts staying down on it's own. I wasn't sure if the topic of nitrItes has come up in any of your other threads, so thought I'd mention it here since nitrItes are also highly toxic and water changes will be needed for those as well before your cycle is finished. If you aren't already, you should be testing for nitrItes at this point also.

I've been testing for Ammonia, Nitrites, and ph almost every day.
