Building a 180 gallon sump from an old tank for a 1000 gallon system and wondering if this would work. Going to use up some equipment I have on hand, in sump bio filter, old mars tank sponge in tank filter and a crap load of siporax and matela.. Any critical comments appreciated. Have to go with only 4 baffles for the weight as I have to build it in one place and then move it into the stand so don't want too many baffles for the excess weight.
