Well i stacked the RIO 2500 on top of each other towards the back of the tank. 1,000 GPH each, but i read that does not equal 2000 gph but just 1000 gph but a broader current.
The Armatus seems to be swimming against the glass in different locations and not happy. Kinda like trying to escape. I covered the tank with towels. Anything else i could do? Could that be to much current?
