Hello all, I am new to this and I need some real help.. Idk what a sump is, or and overflow and need to understand what they are in basic terms because i want to make a wet/dry or canister for my 200 GAL tank. If possible i need to know what exactly i need to do to build it properly and have the right amout of flow/pressure rate. If you can help, please tell me what each thing is in the most basic terms and everything that I will need to make this as far as parts, pipes, pumps, etc and what sizes of each.. I know this will make for a long response but I know the people on this site will be able to help me more then anyone else, so feel free to help a newbie out on this one! Thanks all in advance, P.S If you have any pictures whether of yours or even schematics that would be awsome! thanks all!!
