yes, I'm implying exactly that. Think about it...a container of dirty water flows into another and back....the water cleaner is cleaning at say....300gph (and it's not totally cleaning...it's still letting some DOC
's back into the water column). If you have the water entering the container at 700 gph
...why would it clean any less? It's still only drawing 300gph, no matter how much water is going by it.
Now, slow that flow to exactly 300 gph
. It's still cleaning at exactly the same efficiency.
Dwell time in the sump Makes no difference....it's still only cleaning what it can clean, and the total dissolved solids are still the total dissolved solids, period.
The benefit of faster flow through the sump may be less detritus settling. Right now I have 1900gph running through mine, but my filter socks (two 7" socks) need to be changed out every 3 days because they are clogged with detritus. And bear in mind, I am using two 50 gallon stock tanks.
