Hi everyone

I know that a high pH makes any ammonia in the water a lot more toxic, but how much more? Is there a way to find it out mathematically? I always take great care to keep ammonia in tanks at zero but sometimes with my betta it gets past that. My pH is 7.9-8.0

I found this on koko's before Kissy, not sure if you've seen it before?

Is the second post what is in the link? The link is blocked for me. Hmm.. I thought it would be more dangerous. But I guess that's good! My ammonia is never at .3 to begin with

My ph is at 6.0 in the tank (not sure why, tap water is 7.2), so does that mean the ammonia isn't bothering them much? Neither of the charts have a ph that goes that low.

Btw, Kissy, the link above is another chart with similar info, although it goes a little lower in ph and has temperature factored in.

With four commons in a 10 gallon I am lucky to keep my ammonia at .25, even with daily water changes. They are moving into a 20 soon, until I can get a 55 for them. I think once they are in the 20 and no longer have the yucky ugf maybe it'll get a little better. Still trying to figure out the ph thing though, I have no wood or anything in the tank.
