Paddle Wheel and 3 monkeys for day, evening, and graveyard shifts @ 22,000 gph x 6 bananas per day = $1,247.87 for 10 Years.
Watch out for the Tunze haters Anthony...oh wait, I resemble that! :lol:
The Hammerheads are the least expensive up front and the most reliable, but long-term they would cost more in electricity. Right now, nothing beats a Vortech for electrical efficiency, low heat, superb flow, no wires, no holes, low sound, etc. but there are some of us working on serious departures from common flow methods. Surge tanks are one great way to get excellent flow and a low electrical consumption, but there is no room for them in my man-cave.
Right now there are other devices being built that will put everything on the market out the door for large systems. But they cannot be used on small tanks like under 500g. And that's all I can say about that so don't ask!!
And BTW, 20,000 gph is only half of what I need. I need bursts up to 40,000 gph. Think I should glue my rocks together??? :eek1:
