I changed the filter media yesterday when I did the water change. I have added nothing else. The pH is between 8.0 and 8.3. As for aeration, I have the HOB
filter moving water around, but I don't have any sort of air pump or stone in there. Do I need to do anything else to areate more? I'll keep doing water changes until it gets in line.
As for the main tank, I still have some snails, three crabs (which I'm questioning my sanity on those now after all I have read) and an anemone. So, I've been feeding the anemone which is keeping things going in the main tank.
