The QT tank I use for coral is a 5.5 Gal with a small HOB wheel style filter with floss inserted into it (no carbon or anything else). The suggestion of my tank being “too clean” does make sense. I’m thinking of removing the Chemi-pure, as that was the last form of media added, about 2.5 month ago, then see if the coral improve. I do like the “polished” look of the water with the Chemi-pure. If the removal of the Chemi-pure works, I may add carbon to get the polished look and monitor the situation!?!
Thanks everyone for your input. If it wasn’t for such a supportive community I may have been discouraged and given up on the hobby!
