Greetings, I was /very/ recently given a nice FOWLR setup and I had a few questions. My understanding is the live rock needs lots of water flow, does this need to come from power heads or can I direct the out put of my high flow canister filters (extras from carious freshwater tanks) at the rock? I want as little equipment visible as possible. Will putting a protein skimmer in a sump reduce it's effectiveness? I am guessing the transport of the live rock was pretty hard on the organisms living in it, what care should be taken to keep things going? This was a transfer so there was no choice but to remove fish, rock, substrate; move tank and put it all back in again in one night. Again this was a quick and ugly move and we had to mix 15ish gallons of water. What should I look for to see if the salt was toxic and hard on the fish? Is there anything I can do to mitigate this? Thanks Much!
