Here is my current setup. Only problem is the reeflo hammerhead barracuda is not enough with all what I have going on. I have tweeked and played an barely getting any flow to each tank. I was suggested the model 8100 on this page http://www.calponds.com/Elite-Pumps/Elite-5000-High-Head-Pumps-p-6705.html only problem is the electric is so high. I don't want to re do a manifold I bought. But I need a lot more head pressure and gph. Any ideas? Looking to buy a pump asap as the reeflo is currently running. The manifold is 16feet long and 3/4" pvc.

are you running 1" pipe for all the return lines all the way to the utube with spray nozzle?
 
also..i see how the pump is plumbed to the tank return line as well....larger to smaller 1 ' line on the ...you are choking the pump off.....you want to use larger PVC all the way up to give it the most flow fro the pump then...go to smaller line.....what you can try is close all the ball valves and crack them one by one..just a little bit...start with tanks farthest away from the pump to even see if the pump will get it there.

What is the total volume of water you are dealing with?...looks close too...if not over 600 gallons..right? and what size pump do you have now?

You may need to rework the Up pipe from the Pump to make it work...but it is a easy fix ..it should work...pm me and I will give you my number and we can talk about it
 
The pump you are running is a low speed pump which is not ideal for your application. Low speed/low pressure pumps are generally 1725rpm. High speed or high pressure pumps in the 3400-3600rpm range as you mentioned will consume more power.
Suggest you look into a higher hp pump but stay at 1725rpm. Obtain the preformance curve to make sure you will get the volume of flow you need. Energy consumption of medium pressure pumps are still reasonable.
Generalizing:
1/15hp, 1/8hp, 1/6hp, 1/4hp = low pressure
1/4hp, 1/3hp, 1/2hp, 3/4hp = med pressure
3/4hp + = high pressure
 
Kendragon You are right I talked to several people who build large system and some who build for petco. So I ended up ordering the elite pump where the link is attached on my first post.

The entire manifold that I made is 3/4"

I will keep every posted on the new pump when I get it soon.
 
the pvc looks nice. is it primered and glued already? it can be challenging running that size (and bigger) pvc. looks neat.
