Oh ya the ATO is great.. So easy to setup and has worked flawlessly.. Not sure what any of them are.. Im pretty sure they werent aptasia so I wasnt too worried about it. It also has a large yellow 'blob' of something on the back side of the rock, not sure what that is either..
I love eggcrate, it has so many uses. Since I had to use a smaller sump than I wanted to, I dont have space for a separate fuge so I just put the chaeto where I had room. Its doin its job too, already my nitrates are down under 10.. Thanks for the positive comments, everyone who has seen the tank (had UFC party on Sat night, lots of friends over) loves it and there arent even any fish in there yet..
