I tested my 50 gallon tank that I'm cycling, and it read Ammonia 1 ppm (yikes!), Nitrite 0, Nitrate 7, pH 8.2. I've been doing a 50% or more water change every day trying to keep their ammonia down. I just tested them again, and the pH is 7.4!!! The tap also reads 7.4, but sometimes it reads as high as 8! How do I keep their pH from changing all over the place, and is there anything I can do for them right now?

Hmmn, it sounds as though it's the tap water that keeps fluctuating. Once your tank is cycled it's not such a big deal for your fish when doing smaller regular water changes, such as a 30% change. The pH difference will be reduced once it is mixed with the tank water.

When cycling a tank it is good to try to keep the pH as close to neutral as possible as ammonia is much more toxic to fish at higher pH levels. eg, at pH of 7.8 even 1ppm ammonia can be lethal.

Seachem have a nifty little product called "pH 7.0 Seachem Neutral Regulator" which readjusts high or low pH to 7.0 AND removes chlorine, chloramines and ammonia. !!! WOW - sounds just what the doctor ordered. lol

Got it! That stuff is cheaper than most of the other water conditioners too!

Our city water has a ton a chloramines, the tap water tests at 1ppm ammonia. Will the Seachem take care of it ok, or should I use some Amquel too?

Sounds like your city water isn't the best - when chloramine is broken down it releases even more ammonia, on top of the 1ppm already in the water that's not good. If it were me, I would use some "Prime" or "Amquel Plus" as well as the Neutral Regulator, just to be on the safe side.

ps. remember that regular Amquel doesn't deal with ammonia.
