Opinions appreciated: check valve vs anti-siphon holes in overflow returns

Have you looked at the George Fisher check vavle http://www.bulkreefsupply.com/store/...wiss-made.html

They don't have traditional seals to dry out and foul up, and they come apart very easily to clean and maintain.
I have one and love it! I have been using it for about 7 months now.

Thank you. I saw these awhile back but don't think one will work with my system as the only accessible section of plumbing I could unstall it in is a horizontal run. I would be concerned the weight wouldn't function correctly that way.

The design of them will function best when installed in a vertical pipe, but they should also work on the horizontal aswell. The weight of the stopper is part of the action but alot of the action comes from the water pressure and the valve design. There is a little chamber that deverts some of the back flowing water above the weight, therefore pushing it down.

Hehe, I get that from time to time. It's just redundancy. I had a pair of 250s from my old 125g, but prefer more heaters vs high wattage ones. If a single 200 up and dies, the other 2 can still keep up. If a 250 were to go, a single one would have a hard time.

The 3 x 200W are on the RKE. The 2 x 250W are set a little lower on the Ranco in case either;
-A 200W trips the GFCI
-The RKE craps out in some way
