New tank planing - Which return pump?

[Ryan009]

I currently have a 210 gallon system in the basement with about 75 gallons of attached sump.

Looks like I'm going put another system upstairs in the vicinity of 200-300 gallons (once I figure out what the floor will hold).

I'd like to plumb the two systems together. It will have about a 14 foot vertical drop and about a 35 foot horizontal run in 1.5 PVC.

I have two questions.

Should I run a separate return for each tank or should I feed them both off of one pump?

I'm kind of leaning towards running them both off of one, but I need advice on which pump to use.

As long as it isn't super loud, noise isn't the biggest concern, and I don't mind paying a bit more up front to get something that is reliable and has lower energy consumption.

Suggestions?

I use a reeflo Marlin against a similar head pressure for my 300. It is a pressure rated pump, and uses about 350 watts if I remember. I also use four eductors on my return nozzles and like the pressure it generates to push through the eductors (which add about another four feet of head). It is plumbed through a single 3/4 inch PVC.

I would go with a single pump for simplicity and less energy / maintenance etc...

I am running a Sequence Hammerhead to provide the return to 4 tanks. There is a 9 foot rise and 4 horizontal to three of the tanks and 9 foot rise and 15 horizontal to the 4th. Total display volume is 508 gallons. While I cannot give the exact gph to the tanks, I have throttled it back a bit on three of the tanks.

I also have a manifold to feed the various reactors. Like FishTruck, I like the simplicity and cost effectiveness of running the single pump.
