I'm getting equipment together for my 40Br build. I have a lot of LPS
/softies in the tank, so I don't want them to blow away. I was thinking of using a Sicce 3.0 as the return (about 550gph at the head height I have).
I am going to use my HOB
Eshopps PSK-75H skimmer (mod'd slightly to lengthen the input/ouput lines) in the sump. It's pump is rate at approx 350gph. Should the return pump be sized a little closer, say the Sicce 2.0, which gets around 350gph@4ft head?
Also, in the DT, I don't want dead zones, but I don't want my LPS
getting blown away. Taking into account the return pump flow, would 2 Koralia 600's be too much? Basically, I'd have them on opposite sides of the tank, pointing almost at each other to create some chaotic flow. Or should I downsize to 2 of the Koralia 425s?
There are a lot of variables at play here. Is there a "better" more generic flow rate number (ie X times the DT volume through the sump and Y times the DT volume using powerheads, or a total flow of Z)?
