Well, we did it. We sold all of our corals and cleaned out the tank. The parameters were non existent. Honestly, there was no reading on the test kits for Calcium. Not good at all. Way too much hair algae. So now we are going fish only with live rock. Any suggestions on fish choices? Any tips? We are in the rockscaping stage at the moment and will be looking for fish in the next two months. 90 gallon tank. Wish it was bigger but we have no extra room.
