Turnover rates & waterflow

[andresont]

In the display tank i have 90x times turn over Not counting the Wave Box (if I added the g/hr correctly) . But this is still nothing compare to what is going on in the ocean imo.
Corals are happy including touchy LPS (Gonioporah).
The return rate is very slow only like 90 Gal /hr (Eheim 1250@5 feet head)
the reason is that my skimmer is not in the sump so this is just to get cheato growing and to hide heater etc.
However even if I had my skimmer in the sump I still would have slow flow in order to get my skimmer time to process the waste.
