Hello guys.. I just joined the club with a 250G tank, got a great deal from the LFS and just couldnt pass it up. I had a reef tank for a year a couple of years ago. Now the tank came with everything and the LFS guys installed and set it up as well. The only thing I dont like about it is the stuff in the sump. It has 5 chambers, 1st is the water coming from the overflow, 2nd chamber has cotton rolls, carbon bags, bio balls. 3rd has a UV sterilizer or something like that. 4th has the skimmer and heaters, last is the return pump. I would like to set it up the best for a reef, so should I take out all the crap thats in there? I'll post a pic to show you exactly whats in there. Let me know what you think, Thanks
