Normally I open it to fill it but that's a pain. Right now the intake keeps pulling out all the water, so it's totally empty. I tried to siphon water into it but once again the intake just sucked it right back out (yes, the intake was being an outtake).

I don't understand how your reactor is hooked up.

I think we need pics.. sounds like you have a issue with the way you hooked it up.. a couple pic might clear it al up in our heads so we can sugest a fix

Hello,

Try to place a large bucket of water above the reactor, remove the siphon hose from the reactor, place one end of the siphon hose into the bucket, suck from the other end, and as you see water is travelling through the tube, quickly connect it back to the reactor. Make sure you have a long tube though.

Or you could attach a mini jet to the reactor inlet line end and turn it on when filling only. Or modify your recirc line by adding a JG shut off valve (like the pic I set you a while back) to assist refilling. I am assuming this is the same reactor you had last year.
