Hello, recently I had to restart my saltwater tank due to a disaster. My parents wanted to paint the room and we are assuming that the paint's fumes mixed with the water somehow because it became very cloudy and the water parameters were off the charts bad. Anyways I gave away the survivors to my lfs and I restarted the entire tank. It's a 40 gallon with a canister filter running currently, but I'm planning on building a sump to run with the canister filter ( would I need the canister filter if I had a sump with a protein skimmer? let me know please ). I have some live rock in the tank but I plan on getting more later. Any suggestions on what fish I should add? I plan on having a reef tank so coral ideas would be great too!
