Been looking through some threads but no luck as of yet, so I thought I'd ask. Building my second sump ever. Planning socks in the first chamber, moving bed with K1 or similar and maybe some submerged media in there somewhere. Not sure of the order just yet, but my main problem is figuring out how to determine the water level in each chamber. I built my first one and the water level is way too high in the wet/dry section. Don't want this problem again. Do I even need a wet/dry if I have the moving bed? I need to know what determines the height of the water in the chambers. I know it is the baffles but I have looked at several sumps and can't figure out which baffle determines the height. If there are any plans out there that I can look at, point me in the right direction. Or feel free to even design it for me, I am wide open to suggestions. It will be my only filter for my 150gal. Tank is a 40 gallon breeder, the return pump is a eheim 1262, overflow is 1 1/2" pvc. Will be using 1/4" glass for the baffles and can get plexi for anything that needs drilled, ie: drip plate, walls, covers, etc. Thanks for any help and info that you can provide.
