Hey there,

I've got a couple thoughts;

1. Don't use a spray bar, just have 1" elbow returns near the water's surface. That will provide less turbulent flow but the same amount of water movement through the tank. This will keep your plants from getting blow sideways.

2. Drilling a 1/4" hole in your return plumbing just below the water's surface will break siphon when power's out. If you feel more comfortable with a bigger hole, that's fine too. I usually drill it so it aims at a 45* angle toward the glass downward from the water's surface.

That's it for now, phone call that I have to take

I've never regretted over engineering a system, but often regretted under engineering one.
