Hey guys, I am having issues with my Filstar XP3 canister. It was working fine when i had it running on my 37 gallon, then I switched it to my 75 gallon and the flow dropped substantially. So, last night, I re-primed it i hopes to solve the issue, it worked! but only for a little while, when I woke up this morning, the flow had dropped again. It feels like it is just sort of trickling out of the outflow. I checked all of the hoses and every things tight, no leaks anywhere. I tried looking on their website at their FAQ, but it doesn't seem to be helping much. Suggestions!?
