Yea, about 72 or so. I think I was thinking of the Pan World 250 PS vs the 200PS, huge difference in draw there for the extra flow. Get what you need, but I am very glad to have the Iwaki 70.
Here is my 465 BB SPS tank the Iwaki powers. I have six Vortech MP60s for in-tank flow.

I haven't heard of catastrophic failures from leaking Reeflo pumps either, and maybe I am anal about it, but the only good leak is no leak, IMO. I cannot and do not tolerate it from my equipment.
Pan World pumps have been very reliable for me, and are a great choice as well, IME. I bought the Iwaki 70 just because I have never used one, and it is the standard in the category.

I uderstand the concerns with the leaking seals and infact expect to need to replace mine. I've helped replace a set at my buddies shop and for me it was no big deal. That's just me!!!!!! I prefer the quiet operation and lower cost of running if I need to replace the seals every few years I'm good with that. I've never heard of catastrophic failure either using reeflo. I think it boils down to what your willing to deal with. What brothers some folks isn't a big deal to others. I think all the pumps talked about here will do a fine job in your system.

Wow, your system is amazing! That makes me rethink the 100 model if you're running yours with a 70.
Does a chiller run off of it too?

I get what you're saying about the maintenance not being a big deal to you. I hope you understand this isn't an attack on you by any means. I'm trying to make a decision between two brands and want feedback on both sides of the fence. If I was to purchase a reeflo pump, I think I'd run it from my garage with two ball valves and unions for quick disconnect in the case of a leak. I think I'd also purchase the carbide seal in the beginning to see if that prevents any leaks from the beginning.
I'd really like to hear from reeflo owners who have had theirs running for several years with/without issues. It seems all the great reviews are within short term experience.

I didn't take any of this as a personal attack at all. I think its great to hear from many folks running different pieces of equipment and make an informed decision. I'm curious about the carbide seals your talking about. Do you have a link to them. I might get a set and use them if/when I need to replace mine

The part for the hammerhead was "US Seal PS-1905" retailing around $40. I went on sun play.com and saw one for the other shaft size retailing around the same, but it could be a small gamble since it hasn't been confirmed that it fits as well as the other.
On the other forum, someone kept complaining about their pump leaking every few months until they bought this seal.

I run a panworld 150 from a sump in my basement. Way more flow than I need for my 195ga. The 100pxx would have been great for a sump on the same floor. Panworld are very similar to iwaki designs. I read the same isue with reeflo seals leaking and reliabilty out weighs all else for me.
Also look into noise on what ever pump you decide to go with. Some are more quiterer than others even within the same brand.

Thank you. I do not run a chiller on this tank. It is located in my basement, and the equipment is behind the tank in an unfinished/unheated area, which stays a little cooler anyways, and I have a fan programmed to come on and blow across my sump if the temperature rises too high. I am running 4x 400 watt Radiums and 6x 110 watt VHO Super Actinics.
The Iwaki is hooked up to a 1.5" opening in the sump, and it outputs to 1.5" plumbing. Basically a straight shot to a Tee, then divided into two 1.25" returns, one on each back corner of the tank. There is also a 3/4" side tee just up from the Iwaki output that I have plumbed to a manifold. this runs two media reactors. I also have a calcium reactor and a sulfur denitrator, which I run with Masterflex peristaltic pumps.

Two 4"x20" media reactors run off the 70.

My Iwakis are quiet, btw. I don't know why they have a rep of being noisy.

I run a Reeflo - GOLD SERIES Barracuda hybrid my sump is in the basement - it has tons of pressure - I also run a frag tank, fuge and 2 reactors with it and have enough pressure to add another tank if I wanted to. I can not speak to Iwaki but I am very pleased with this pump.

It looks like a 70 would be more than enough for what I need. That is an awesome setup.

I don't think they're loud, and that's not my concern anyway. My main objective is conserving energy and reduce heat in the water. My two mags need to go. I'm pretty sure I could honestly run everything off just one of them.

I agree with you too. I was just attracted to the idea of only using 100 watts off the pump. After reading all the leak issues that reeflo has along with time consuming process of replacing the seals. I think I'm going to go with an Iwaki 70 since I know I'll get at minimum a decade of use out of it. Plus it looks like I'll be able to use the same pump for a future upgrade in size later on.
Thanks everyone for your input. I feel pretty good about the decision now.
