View Full Version : pH swings and Rams

04-03-2008, 06:27 PM
I have tap water with around an 8 pH or higher sometimes. I don't want to have to add pH neutralizer so my 20g long has 3 pieces of driftwood that keep the water at around 7.0. When I do a water change I usually do about 25-30% at a time so as not to swing the pH too much but I'm sure there is a rise in the pH for a day after a the change.

My question is what is too much of a pH change for my new GBR to handle at water change time? And what signs should will they show if they are not handling the pH change?

I say you would be fine at a 20% water change. I usually do about that much and it doesnt affect my rams.
