throttling eheim classics with double tap connector
I just set up a 2215 on my 29, its running with an aquaclear 50 that I'll remove in a couple days which it is supposed to replace. The pressure from the spray bar is ridiculous, I noticed it more because the water level in the tank was low so i topped off the tank and could see a lot of water movement. It blew over a lot of taller plants and I noticed my angelfish was staying near the bottom half of the tank.
to help I turned one of the valves on the input tubing like 1/4 shut, is this bad for the motor? the only thing i can find about it are people saying to turn a valve on the output side but I can't see how this makes a difference
