I put a small hole on the very top of each tube. I then glued some airline tubing in there sticking it just barley in. The i hooked both lines into a t then into my power head. I have been running this on my 65 for about a year and never lost prime once.

I seen someone do something like this on a cpr style overflow box ( the one that dosent use tubes). So i thought it would work for me to.

The CPR one are made for using a aqua lift pump to pump them free of air but using the veturi from the powerhead is a good idea.
