Why is a closed loop a PITA?

If it was me I would use one of those DC10000 pumps for a return with 2 or 4 nozzles, and then get a bigger pump for a closed loop. Those DC10000 pumps aren't near big enough imo. I would be looking at a Reeflo Hammerhead for each OM which would still only give you about 35x turnover.

Well it isnt you I have a closed loop on the 165 now and I dont like it because sand gets into the suction side and has damaged my 4way drum to the point that I cant use it until I replace it.

Not to mention the noise of a hammerhead pump terrible, also had one of these on my 165 and I could hear it up stairs in my bedroom. This is a low noise, low power consumption build.
ATO will have sensor in the smaller side to monitor the level and top it up balancing them both.
