sump water level
Ok. I can't find the specifics I want in any of the material I have read. This probobly means that it is dead simple and anyone even slightly aware would see it right off. I am building a system with a sump. I have read that I do not need valves to regulate the water flow into the sump if I use an overflow box. I see that as long as the sump can hold the water from the overflow box you will not drain the tank from that end and if you put a backflow valve in the return you are ok. However what is to keep the overflow from draining too fast, losing suction and then the pump draining the sump. This would still cause a flood and and burn out the pump. What am I missing?
Also I want to put a pre-filter, co2 injector and fluidized be filter in the sump. Should I do this inline or as seperate units with seperate pumps. Should the pump be at the front end or back end, whether of a whole line of equipment or each individual piece? I have always used in the tank or hang on the back equipment but I don't want to look at it. Also, I want to set up a reef at the office and I only have room to go up not out. If I built a very tall tank it would not get enough light. Building the sump will let me get around this by having a large water volume for stability but a smaller habitat for view.
