OblongShrimp Posted November 7, 2015 Report Share Posted November 7, 2015 As I am increasing my number of tanks I broke out my AV-150 again to run some new tanks. It is currently running 6 HFM filters (4 10gal tanks and 2 15gal tanks). I tried to hook up 2 40 gallon HFM filters each with 2 outputs and it doesn't seem to have the pressure to run it correctly. This morning I tried hooking up my AV-50 (currently being used on some other tanks) and it ran the 40 gallon tanks just fine. I am thinking some of the rubber parts in the AV-150 may be shot (filter is 8 yrs old or so now). I read that they still sell these parts under AP-100 now and I can get them at kensfish.com. Does it make sense that the diaphragm or something is just going out on it? I plan to take it apart to check it out but I just disconnected it and it is way to hot to touch and work on right now.
