I guess I got my terminology mixed up. I didn't mean on the return for the filter sock. I meant on the return from the overflow so like you said, the drain into the sump.
Great point on the filter floss. Will it trap tiny life in it or will it just keep it from passing to the return pump? My trap is after the fuge so if it just keeps them from passing to the main tank while it's being used I'm ok with that. If it's trapping life inside then that kind of sucks..... It's probably best to do filtering before the fuge I'm thinking?
The live rock that I used was in the tank for about a year. Then placed into 5g buckets and transported to my house immediately. At that point it went right into the tank. There was also some rock that went into the tank that was just cured. Had been in a tote for a month or two with a powerhead and heater.
If there is no ammonia spike, just let it go a couple weeks then do a PWC
and start with a few live stock?
