Ok so looking at the eshopps HOB overflows there are a variety of options.
Running a LPS torch dominant tank at the moment and I have flow between 20-30x's. My return from the fx6 says 900gph so realistically 450ish gph. Then I have alternating 1900gph hydors acting as a wave towards the top going the lenght of the tank. Probably a little excessive so im trying to dial it with this set up. I'll be getting something controllable this time.
I want to take your advice about enough overflow to the sump.
So my question...would an overflow of twice the suggested gph for a 75g tank by eshopps be what you are trying to hint at would be what I should go for with the overflow?. I dont want to run into too light of flow to my sump, I also done want a waterfall lol
I hope that question makes some sense hahah
Here are theseries they make and I'm thinking of getting either the 1000 or 1200 to make sure I have enough to the sump. Then of course a controllable return to match the overlow.
Thanks for the help!
