I just installed this system and there was a few things i think perspective buyers should be aware of.
1. The metal reservoir Inlet fittings are screwed into the plastic on the top. when you go to tighten the tubing make sure you use 2 wrenches. 1 to hold the base fitting and the other to tighten the tubing clamp. i used 1 and stripped the plastic threads an 1 turn i had to use gorilla glue to get it back on.


2. The pump needs a little shaking around when you first put fluid in it. bubbles or something get in the pump and it hums till you shake it around.

the light side is the sensors work well and the pump works well all the way up 24 inches to my res.
