is there a way I can calculate how tall will the sump have to be, without actually water testing it IRL? for this reason i actually located the overflow quite high in the display tank so that there wont be much overflowing going on. (does that help?, or am i causing more problems? like noise etc.) for the skimmer wise, I designed it so it fits my current fluval skimmer, rated for 15-20 gals. I know that that slot can also fit an eshoppe skimmer rated for 30gals if need be. I didnt allocate a large compartment since technically i’ll be having a large “fuge” for nutrient export (i would also ru
I do think this is going to be an issue. Your return pump compartment has very small buffer for additional water. Perhaps you need to build a taller sump.
Chaeto are used because they are resilient and efficient in exporting nitrates and phosphates. I noticed your skimmer compartment could only house a small skimmer. You may have to keep an eye on how your nutrient management goes.
Lastly, critical. You need to design a emergency over flow for the filter sock holder. Perhaps cut some slots near the top of the baffle, or reduce the baffle height a bit. So t
