Aquarium Advice FINatic
I know the general opinion here is that pH doesn't greatly matter as long as it's somewhere between 6 and 8, and the fish get used to pH changes in a gradual manner.
Here's my problem. I thought the last batch of cory eggs a month or two ago was a misfire... most were eaten, I'd tried to save some in another tank, but again they were tasty lunch for someone. So now today after a larger than usual feeding, 3 1/2" fry popped out from behind the java ferns, and now I probably have more cories in the 29G than I should. (Heck there may be MORE than 3 fry, I can't tell).
the pH in this community tank is notoriously hard to keep up; I blame the gravel, and maybe the black algae that keeps pulling calcium out of the water. Currently it's about 6.0. My other tanks are at 6.5, 7.8 and about 8 (the betta tank, which has new gravel and new water). Would it be too much of a shock to move either young or mature cories to the 20G tank with a 7.8 pH in it?
edit: local tap water is about 7.7 pH.
