constant ph battle

[jhm]

when you lower the pH how low do you put it?

Good question. I suppose I go from 7.8 to 7.2 or 7.4, something around there. I try to keep it in the recommended range. You think that's causing it to rise quickly?

What is the TA of your fill water?

110

How are you testing the water?

k-2006, I mentioned that already, but maybe I'm missing your question?

Thanks!
