Hi all,
I had a beautiful red oscar for 2 years, but then lost her during a change to a new, larger tank.
Since then, I have added a 10 and a 20 gal tank in addition to the 55gal. I've been having severely acidic water problems. Tap water registers 7.6, but the tanks always drop down to 6.0 with time. Other water values like Nitrite, Nitrate, hardness, chlorine, ammonia are fine.
What is causing the pH to drop so far down? I have fancy guppies in the 2 smaller tanks and a baby oscar in the large 55gal. Filters are changed at least monthly, ~25% water change every month. The guppies are dying. So far the oscar is ok, but I'm worried.
