Well I'm working with a lot of stuff I presently have to step up to a 125 from the 55 I have now. I plan on having the 55 set up as the sump for the 125. My first question is how much flow do you reccomend I have travel through my sump? The fuge is going to be a 30 gallon tank I have up high and gravity returning to the DT, so that's not a factor in the sump. I do however want the sump to be somewhat of a "benthic zone" in order to grow some natural filtration, so I will do my best to get it very low light, if lit at all.
Any design suggestions? As far as flow from the DT I was going to install 2 2" bulkheads (the extra for redundency). The reason for the large size is that I'd like things to be as quiet as I can make them, and I had read that the bigger pipe will keep the noise down.
Should I join the 2 overflow pipes into 1 before they hit the sump? I was going to try my best to have them on a slant instead of straight down (again for noise reduction).
For now the skimmer in the sump will be my Aqua C Pro driven by a Mag 7, or I was thinking I could use a larger return pump and use it to drive the skimmer as well, maybe even feed the fuge. I was concened however that in that application the 1000+ gallons flowing down to the sump would be awful loud?
I was considering having a remote DSB (in addition to the DSB in the fuge) installed between the overflow and the sump, good idea or not?
As far as the fuge is concerned I was going to have it fed by a Mag 3, is that enough or too much flow?
Thanks for the help as always
