check valves!!!!

[nl5882]

Ok I have s tunze osmolstor setup, which is fed into my a vast kalk stirred. I'm tired of it back siphoning. I got by for the longest time with cheap check values from petco. Then I purchased some medical grade check valves from aquarium plants, which didn't last any longer. After these I went to the tunze check which really work well in my co2 line. But sucked for my kalk setup. Any others out there have a better one they use?

Try the koralin off the calcium reactor.

I use dennerle check valves on all my calcium reactors. I feel they are the best. About $25 or so.

I looked at the koralline but it's brass, can't use that on top off line can I?
I think I'll try the denerle Im not sure if it is big enough since I believe it's 1/8"

Use the search function on this forum. I posted a thread awhile ago about US plastics check valve that I use. A bunch of people ended up buying them, and no issues.

I found the part number on a thread about modding a Korallin calcium reactor
