Snail Profusion and Dropping Ph
Recently we have had a profusion of Malayan livebearnig snails and the common Pulmonate snails. (Yes, we overfed). But the real problem is that the PH keeps dropping drastically -from 7 down to 5! We increase the Ph and in just a few days it drops again. Various Ph equalizing chemicals don't work!
No new objects were introduced except a common aquarium plant and I can't believe the plant could cause the Ph to drop by 2 full points.
Did a complete break down of aquarium, washed gravel, scrubbed glass, replaced 80 percent of water. A few days later Ph drops!
What is causing this or how can we figure this out? Could the snails be causing this?
