This is my first post on my tank. I started this tank back in November, 2020. I bought a 15 gallon Aqueon frameless cube and 5 chunks of dry rock. I fitted the tank with a small HOB filter and a SICCE powerhead. I went through a bumpy start since my beginning stocking of two clowns contracted marine velvet. I left the tank fallow for 8 weeks to make sure that my next stocking did not meet the same fate.
