Playing around with my sump plumbing right now and having some trouble getting things right. I have a 75g DT/30g sump and was running a Hydor Seltz 740 gph pump. The overflow has a 1" drain, 3/4" return which I believe is associated with an overflow rate around 600 gph. For a while I thought the return pump must've gotten clogged because there was very little flow returning to my display tank. All the pvc was glued so it wasn't as simple as removing the pump to check for clogs.
I cut the return line so I could replace the return pump with a new Sicce 950 gph pump. Turns out the Hydor pump was probably malfunctioning. I opened it up and there was some detritus build up but not to the extent that it would be affecting flow. The new Sicce pump is 200 gph higher than the Hydor but my overflow can't handle it. I thought it was a small upgrade from the previous pump but that thing is kicking like crazy.
I just got a new frag tank that I want to plumb into my system and was wondering how to calculate the GPH required to achieve this. There is a head loss calculator on RC but I'm not sure how I'm entering the vertical/horizontal lengths if the return is split.
The layout would be: 2 ft vertical rise from the return pump to a tee, the DT return would then go 3 ft horizontal, then 2.5 ft vertical. The frag tank return would go 2 ft horizontal from the tee then 1.5 ft vertical. 3/4" plumbing.
Any thoughts on the 950 gph pump being used for both? I'd rather not have to buy more equipment than I already have but the Hydor pump is just no good and the Sicce is just too strong....
