Hey guys , I have been running a 150 tank for a few years when I first started I had a wet dry system well I guess as time went on adding a skimmer a refug and other things I always have to watch my water level. I was going to add a bigger sump but the tank is filled and the stand is not big enough to get one through the doors. I though about adding hard plastic container or soemthing.does any one use any thign like that??? pic would help I stink at plumming
