Does it really matter whether you put the sump in 1st or second chamber of your sump? I thought of putting a sponge and chemi pure in first chamber and then sump in the second. What are your thoughts?
it will have 3 chambers. 1st chamer will be where i put sponge and chemipure. 2nd chamber will be skimmer and last chamber return pump. I haven't put in baffles yet just have the design on paper
