Phosban reactor?

I was recommended to get a 2 little fishies phosban reactor for my high nitrates. I am ready to buy it, but have some questions on the technical aspects

1. What type of tubing do I use? AIrline?
2. From ground( where it will be placed) to tank it is 4 feet. To get 80 gallon flow rate per hour, what rate of flow pump should I buy? I read about head pressure but got really confused
3. Do I need 2 pumps or is there a type of siphon I can buy for a return line?

Sorry I know this is a lot of questions, but I really want my nitrates gone!!

Thanks so much

so a reactor isnt going to help with my nitrates?

 

it will, you need to decide on a gfo/carbon reactor or biopellets! but they will help

Phosban recators have a built in bracket so can hang on the rim of the tank or sump.

If you were to place it on the floor you would need 1/2" inside diameter clear tubing to go to and from the reactor. The head calculations really don't apply in this situation because you will have a siphon from the display to the reactor so its basically 0 Head, all you have to do is move water as in a closed loop which is essentially what you have.

I use a MJ400 powerhead on my reactors and the flow is about right once the ball valve is adjusted down a bit. If you are looking at Biopellets you would have to find the proper flow rate for them since it may be different than GFO or carbon.
