lets discuss.
many have said for a long time that a slow flow rate through the sump is better as more dwell time in both skimmer area and a refugium is important. others say that it really only matters that the water is long enough to make sure it is heated properly (for those with all heaters in the sump).
personally i have never really put much thought into the flow through rate of the sump i think it might make for an interesting discussion. i have in the past made efforts to set up benthic zone filtration areas. which require very low flow but had very little success until recently where it seems to have formed accidentally.
how fast or slow do you think a turn over rate should be? what are the reasons?
