closed loop question

[dragracer]

ok so I went ahead and built a closed loop system to eliminate powerheads. I got it up and running by priming it. I put a T in the intake to prime it so I would be able to cap it off when its running. I can't glue the cap on in case I have to re prime it for some reason. The problem I am running into is that it is sucking in air and every 15-20 seconds it blast tiny little bubble out both outtake by the millions....is there anything I can do to prevent this?

i sort of lost you here. a picture would help. a closed loop doesnt need to be primed...

hm, really? The pump would have enough suction to start on its own.......I don't have a pic of mine, but I built it off of one I saw on here......give me a minute.

I built it off of the picture here except on the second 90 of the intake I put a T so I could cap it off to prime it......unnecessary??

ok thats what i was thinking, you built an over the top one. once it is primed you shouldnt need to prime it. close it tighter?

ok, well I guess I can try that and maybe throw some silicone aquarium sealer around it that way if I ever need it to come off I can get it off.

silicone is only for glass.
