Its a 30 gall tank. The tubes would be below and above the tank to make circulation eaiser. No i have not hured about iron poisin through the procces. Its hard to find a site that discribes the procces. High preasure would be about 1.5 psi conserding a
power head at my store puts out about 4 psi at the nozzel (so it claims).
Since the 2 tubes would only be 3 fee or less above the tank. Max 6 feet total. And the siphining action would help reduce the water wieght. So a lowe preasure pump would runn it. After i get the tubes and wiegh them I could caculate the actual wieght the tubes with water--thus telling me how much my pump would work. Even by installing a large air free seald container I could make it a pump free system (like a water tower) the weight of the water pushing back into the tank would be less then the waight of the water pulling from the tank..Their for a contuois syphoning action would occur. But i would be at risk for "stallin" if the flow got interupted or surged.
