Sump
Went with a simple sump designl. Water goes in from left to right. 1st is Skimmer partition which will become a frag or fuge area afterwards as I'm upgrading to an external skimmer. Next partition will be a DSB and a Fuge. Yep that's right I still believe in DSB at least remote ones so I can take it out or restart it if needed. after that is a second set of baffles and the return area with 2 outputs of 2 external return pumps. reactors will be placed in this partition or maybe on top of the sump Stand.
Got two sets of baffles with 5 cm separation between the baffles for slower water flow which give more time for bubbles to burst.Reason for this is that I expect to run around 5-6000 GPH through it as it will be handling the DT, Frag tanks system, Cube tank and potential additional Tanks.Also will have water draining from tank to the basement so around a 5 meters drop.
Sump should be able to handle around 230 litres of water draining back to it when return pumps are turned off and that should be enough for all the water in the piping and tanks.
Wanted to go even larger but the limiting factor was the stand size we could fit through the basement door, Ended up with a 68x28x20 or 160G Sump.
Most important is that it's another DIY project and the biggest glass tank I've built myself so far.

Water Testing done and filled with new saltwater to startup the cycle.
