What do you want to know? As you can tell i designed and built it based on my of fluids and pumps. I used oversized 1½ returns and a 2" "manifold" to combine the flows. The 1 ½ return is 2 cor20> 2 flap check> combined with 1½x1½x2 sweeping Tee> 2" motorized return 24VDC NC ball valve> 2" Apex flow meter> another sweep TEE then across to the penetrations where spray bars will be. The drains are 40" trench drains, each one flows to each end of the sumps (dual 40g breeders) left tank is refugium and right has octo 300 int, 57w uv loop on octo varios6. Both tanks are built identical to assist with flow. Once it goes through treatment they over flow into equalization chambers where a 1½ flow through can equalize water levels. Between the tanks. My flow is designed to be able to turn off one pump and essentially i can remove either sump totally from the system and the main system can still function so fosh never know there is an issue. Im currently only running 1 cor 20 on the right tank and only at 50% with no issues. I have figured head to be less than 9 feet because of the sweeps and 45⁰ fittings. I have some pics added. There you can see when the tanks pumping the eurobrace creates a compartment that allows for a top flow. There are lots of carnivores so the protein needs to be removed from the top. This ensures it happens. Flow in the tank is 2 mp40s
Thanks i was going for a dual island type but i wanted it to be what the animals needed. Lots of crevices to swim around. Places for the groupers to hide and set up shop. A big ledge for the lions to perch under. Spaces to break up line of sight issues for the wrasses. Then optomised flow patterns to try to combat dead areas.
Its my first Polleini and miniautus groupers. I have had panthers before but i lost everything after a tornado took power out for 7 days and i lost everything. Lionfish included. And 3 yellow tangs (the real ones) back then they were cheap.
