Jebao pump decision

[Ron99]

I think about 12 to 14 inches. Not home to measure it right now. But they are about half way up.

I usually place them 1/3 from top when i was running the tunzes in my old tank. Lower usually pushed the sand up for me

I'd recommend the 15's! I just put the 20s on my 300 and I have them on the lowest setting and have to redo my sand twice in the week I've had them on.

Thanks, how far is your pump from the bottom?

24" high tank,I have them as close to the top as I can enough so they don't suck any air. Approx 3/4

I think the RW20's are overkill in anything shy of 7-8 feet long. I bought two for my new 7 footer. I placed just one to test it out in my 79" long 100 gallon and on the lowest setting it blew corals right off the rocks.

The higher up, the more "wave action" they produce. I usually have mine halfway down in a 24" tank. Mine is a LPS-heavy 165g (just under 6') and keeping them low gives me a nice wafting motion, as opposed to whipping the frogspawns and hammers heads right off.

I have 2 rx 8 on a 6 foot 135 gallon tank opposite sides and at full speed they blow all the sand all over.probably the rx15 would be more then enough for your tank.
