pump for closed loop

[tank watch]

I mean to say wavy sea, but I keep typing sea swirl. I want the wavy sea, I want the wavy sea, I want the wavy sea. Just practicing.

The CLoop will use 4 leads inside the rock with a spray bar like structure to support and clean rock. I intend to design a spray section by drilling maybe 1\4" holes in the last piece of hidden pipe. (no holes pointing to the sand!) Maybe with a Barracuda I could use a different drum like the 1+2,2+3,3+4, etc.
The remaining 4 leads will be mounted in the bottom front of the tank, pointing up at the reef and ultimately the overflows.
Perhaps all I need is a wavemaker. Hmmm......

Wave box is nice.I am planning to get one.Those tunze pumps push a lot of water but they are a bit of an eye soar.They do however use a lot less electricity then the dart pumps..The new ones that push over 5800 GPH are pretty big but in a 600 gal tank its not so bad.If you are looking at a 4 ft wide tank you won't notice them as much.

If I opt for two large Tunze units later on, do the pumps need to be placed in a particular area to create a good wave. Or, can they be hidden in the front corners on the side of the glass (plywood tank by the way) at 45 degree pointing inward and still achieve the rocking motion.
