I've read in many places that the current recommendation is 10x turnover in a tank and I've perhaps mistakenly assumed that this meant 10x tank volume through my filter/sump.
I currently have a 40g FO tank with integrated wet/dry filter and have plans to upgrade sometime in the next year to a 72g FOWLR w/20g sump. I measured my current filter return pump at 180gph and was looking at replacing it with a 400gph unit to get that 10x turnover. The LFS said that the 10x is for tank turnover and not meant to mean that much through my filter and pointed me in the direction of a Koralia 1 to get the additional turnover.
1) Is the LFS right when they say wet/dry filters need lower volume and I should just add to my tank turnover with the Koralia 1?
2) Does this change with the use of a sump instead of a wet/dry and the full 10x should go through the sump?
