I have had a mystery snail for a couple months and just got three apple snails. The mystery snail hasn't been looking too good, lately. His shell looks very dry and pitted in the "swirly" part. The remainder doesn't look quite as bad. He has also been excreting some white, gooey stuff. Anyone know what this is? Within the past couple of days, he seems to not be able to (or not want to) fully expand out of his shell. The portion that would normally be against the glass or on the substrate seems to be "stuck" folded in half, and he only opens up about 1/4 of the way.
Since my tank has cycled, I have mainly just tested the Nitrate, but I recently checked the pH and it has dropped to about 6.4. My tap water is about 7.4, and the aquarium was the same during and after cycling. I'm not sure why it has dropped, but this isn't good for the snails, right?
I have a male betta, two minnows, a cherry barb and a chinese algae eater. I had three minnows for the longest time, but one of them died recently. I also had three cherry barbs, but there is only one left now. I only have a 10g tank, but thought I was keeping a good eye on the water. I just checked all levels last night: Ammonia & Nitrite are 0, Nitrate 5-10, pH ~6.5. I've never tested for anything else (hardness, GH? KH?). Where do you find these tests?
I do water changes as soon as the nitrate starts climbing, but I'm confused about what caused the pH to drop. I have four live fern plants and five sticks of bamboo with the roots in the water. I did add a rock from the fish store. I'm not sure what kind it is, but it was really bubbly after I put it in (if that tells you anything).
Anyway, what are some non-chemical ways to raise my pH? Any other suggestions?
I should also mention that I have been battling green algae, but seem to have it under control via a combination of scrubbing it off and the snails/algae eater taking care of it
