I am in desperate need of some guidance. I need to replace my existing Iwaki MD40RLT because I am just not getting enough flow for all my accessories. I currently have a frag tank, skimmer, main tank, chiller, and GFO that requires a pump. At this moment the skimmer and main tank are on the MD40RLT while the rest are on a Mag 3 pump. The flow really sucks on all equipment.
All equipment are connected with a 3/4" pipe (nothing I can do about that now). The pump sits below the tank next to the sump. The MD40RLT is plumbed to the sump via a 1" pipe reduced to 3/4". My idea is to plumb all the 3/4" into a single manifold to distribute.
My requirements are that I reduce electricity usage, get rid of the Mag 3, and hopefully reduce noise level while maintaining reliability. For these reasons I've narrowed my choice of pump to Iwaki OR Dolphin AMP Master Type 4. Not considering reeflo, blue line, or pan.
I know these pumps are designed for very different applications. But would I be ok with a Dolphin amp master diamond 4750 OR should I get an Iwaki MD70RLT?
I think the 70RLT will work for me, just don't like the fact that it doubles power consumption compared to the MD40RLT. I really like the Dolphin but not sure what kind of head pressure I'm looking at. I see there could be some pressure feeding water into an H&S external skimmer. Not sure how much pressure would be on the Chiller.
Not sure how all those 3/4" adds to the head pressure equation. By the way the longest run for the 3/4" is to the frag tank which is maybe a 6ft run.
I appreciate any help. I'd like to figure this out soon so I can get my black friday deals on the pump.
