Hello, I used to have freshwater aquariums several years ago and recently decided to get back into fish keeping and wanted to try saltwater this time. I don't know much about saltwater but did well with freshwater. Now I moved abroad and live in China, and not many people around me are familiar with saltwater or sump set ups and there is only freshwater lfs so I don't have many places to go for information around here. Now here's my situation... I bought a tank 66 gallon with a 14 gallon sump. In my mind, I wanted a coral sand bottom however as I'm assembling the aquarium tonight, I'm realizing that there is a tube inside that has a corkscrew thing inside that moves water up... so it sucks water in the bottom brings it to the sump, and then corkscrews water to the top to return clean water to the tank... Anyways.. how do I put sand in the bottom without it going into my bottom sump...there has to be a way...Is there something I can block those holes with but still allow water to flow through? If so, what's it called? I tried looking everywhere but I don't know what it is, or called... I seen some tanks with a shield looking thing covering something in the corner of their tank (assuming they have that tube thing like I have) but I don't know what it's called and the only information I am getting is "how to filter your sand" help on this would be greatly appreciated...
