Need plumbing advice

[killrblue]

I'm plumbing for the first time on my new 40 Breeder and standard stand. My overflow is rated at 700gph going down on 1.5" drain. I want to gravity feed 3 items if possible, skimmer, biopellet reactor and carbon reactor. All 3 appliances have a 1/2" feed input. I found a t-fitting that is 1.5, 1.5, and 1/2". If I use 3 of these in sequence for each of my 3 appliances (wiith ball valves in between) and the end T exit into sump, would I have enough flow for all of them? The sequence Ts are very close to the first elbow of the drain. I have a Eheim 1260 return pump.

It would be fine for the skimmer but I don't think you would have the pressure for the reactors. The water would take the path of least resistance which would be to flow straight into the sump.

 

I would not do it that way as I think you want clean water going into the reators so they don't clog. I would "T" off the return pump and pressure feed the reactors with ball valves.

I didn't want to close the end T off because I want to prevent the flood back up to the overflow if the drain gets clogged. Water exit into the sump would give me an indicator of water flow/pressure. To me this is my paranoia flood checker for the drain. What if I put a ball valve to increase resistance, between the end T and the exit to the sump? That should give me more pressure to the reactors, right?

 

Is this the normal progression that I should have in the sump? Drain > Biopellet > Skimmer > Carbon > Sump > Return? Should I leave the carbon out of the gravity feed plumbing?
