Kind of what I thought may happen Doug. Probably just go with more power heads you can never have too much flow eh?

You can have too much, but I don't think you are anywhere near too much at this point.

True but it's an easy fix. All one has to do is install a check valve. Or depending on how this nozzle is built you could drill a hole at the top of the pipe as a syphon break.

Yes, but then you have to rely on a check valve in a salt water environment. They have been known to fail in salt tanks due to sponges and tube worms growing in the oddest places in the dark. The same goes for the drill hole- Stuff can grow over it and clog it enough so that it doesn't break siphon. It will have to be monitored periodically for this.

If anyone is considering putting a check valve in line, look for the one you can open and clean. They do make one like that.

This is what I have. Top and bottom screws off and it is clear, so you can see how things are looking inside.

Would it be detritus? If so I also have the issue of it building up on my sand and am having trouble finding a solution.

Yes it is detritus and I have moved my stupid power heads everywhere. Hi, low, front, back and it's always the same 2 dead spots. I can't move my power heads too far down the tank it blows sand all over and if I aim to much towards the bottom it blows sand all over. Kind of at a loss on what to do

Low flow at the bottom of tank

Might just have to hit it daily with a baster or if it's real bad 2x
Edit: just read the whole thing and realize tank is prob to deep for that sorry. Maybe a stick to swirl the water above it?

I have fine sand as well, and have my power heads low and then have them pointed up towards another one on the opposite side to create current. No sand picked up from it. Hope it helps.

Also just an opinion, if you have a lot of dietrus, you may be feeding too much or may not have a big enough cuc.

Get a Jaebo. Those suckers are so strong they PULL the water across my tank from one side into the pump.
