I have a 320gal tank that has to remain fish less for the next 8wks due to a parasite in the main tank. I lost 6 fish and the rest are in QT right now doing well. I was looking at my tank and was thinking about adding corals to my setup. I have a few zoas, few heads of frogspawn and a RBTA. I have four of the marine ecoexotic LED strips over the tank. The main tank has an overflow that drains down into 3 40gal breeder tanks that I have joined with 1" PVC pipe connecting them. In the first tank I just have a filter sock to catch any large particles and waste, then in the second I have some rubble rock and cheato, and in the third I have my skimmer and return pump. I think I may shift everything down one and use the last for a ATO. Is there something that I should look at getting or add to my filtration to keep corals. For the most part I want to keep mostly softies and some LPS, and a few SPS. As for the fish that I have, I have a vlamingi tang, disjardini tang, hippo tang, fox face rabbit fish, and a few chromis. I will mainly add a few small reef safe fish like a melanaris wrasse, two different pairs of clowns, and some sort of blenny and that's pretty much it for fish, I want the corals to add the rest of the color to the tank. What are your thoughts and advice for me. I figured right now would be a great time to add the coral with all of the fish out and then when it's time I can slowly add the fish back.
