sps help calcium reactor pump losing pressure

[colgan10]

I have noticed recently that the pump to my calcium reactor has been losing pressure and i have to get it primed again. I have seen people install maxijets to pump the water into the calcium reactor, but where do you get the fitting to connect the small tubing to the mj? Anyone with experience with this please help, thanks.

I just cut a 1" piece of 1/4" tubing and then sliced it lengthwise, stuck it in the maxi-jet output to act like a shim and then stuck the calcium reactor feed tube inside the shim. It's been working like this for a couple of years.
