Ok going to be currently upgrading to a 115g and using my current 75g as a refugium/sump. Well i don't want to empty out the sand of the 75g and use it as a show refugium. Well that leaves me to find somewhere to put my skimmer/return pump. I was thinking about making a stand on top of the sand with a rubbermaid container that houses my skimmer with holes drilled in it at the 10 inch water level. Then at the other end of the 75g a small rubbermaid container that houses my return pump. This way no sand gets into the containers and i don't have to install baffles. Anyone ever heard of this being done before? Do we foresee any problems?
