Thanks aldiaz. I am definitely going to utilize dual pumps, and am leaning towards a Herbie style syphon.

lolWhere does your "math" come from? Didn't happen to be a Laguna add did it?
I've never seen a Dart read over 150 watts. The ones I have reading 150 are Baldor motored hybrids running 4300 GPH impellars in them. The 3.6K rated ones here read 130 watts. Numbers via Kill-A-Watt. Head a little shy of 6' but they do have some pretty long runs........
My beef with submersible pumps is the maintenance involved in descaling them several times a year if you want to keep them from locking up in the liquid rock tap water we have here in the midwest. I killed 2 Danner Hydrives before going externals and have had very little issues with any of the fleet of pumps I use (1 sequence, 2 Dolphins, 4 darts). I had to descale every 4 months to prevent lockups and even then the pumps seldom made it 2 years. Not to mention one Hydrive would suck about the same juice a pair of darts do.....
Air pump will need to be of good size in order to get a good boil on a moving bed. If someone out there has an air pump that will run with the Pondmasters (cost vs output vs watts) I'd love to give them a look, but I wasn't able to find one.......
For a 600 gallon ray tank i would be going with a bigger pump though especially with your rays getting bigger and wanting to breed them. I run about 7500 gph on my 450 gallon tanks and its about perfect

Chances are I will have to use different pumps than Lagunas because running a Herbie syle at full syphon with a 24" head on the drains is going to get me roughly 7500-8000 gph which the Lagunas wont be able to push.
You nailed it! The issue with submersible pump is either you have to clean it often or replace impeller, shaft, or even new pump if the housing or the magnet gets deformed/damaged from debris or scaling. Plus, real number beat advertised number any dayI like you too?

lol, I was just trying to take the edge off of my post when I said I liked you since I was about to disagree with what you were saying (I'm bummed there is no kissy face emoticon). I like to be nice when I disagree with people these days. Hi John =)
To answer your question, I used the advertised performance figures posted by each of the pump manufacturers. It sounds like you are saying the Reeflo pumps push more GPH than they advertise on their own performance charts and they actually use less power as well. I'm not saying that's not the case (although it would be weird if they did that), but I'm just going off of the numbers they put out. Perhaps your pumps are older models?
I posted the Performance chart for the Laguna pumps above.
Below are the performance charts for the Reeflo Pumps.
Based on these charts, the Laguna pumps are more efficient than the Reeflo Super Dart Gold and the Reeflo Dart/Snapper Hybrid (regardless of what impellar you are running). Unless my math is wrong, that is a fact.
The Dart/Snapper hybrid model that you mention is even less efficient than the pricier Super Dart Gold version.
The Hybrid with the Dart Impellar does 2,428GPH @ 6' head on 155 watts = 15.7GPH per watt
The Super Dart Gold (as I mentioned above) does 3,191GPH @ 6' head on 185 watts = 17.2GPH per watt
Laguna Max Flo 4280 does 2,935GPH @ 6' head on 160 watts = 18.3GPH per watt
In regards to the durability of the pumps, you may be right. Hydrives (from what I hear) kinda suck, so we'd have to stick to talking about the pump in question: Lagunas. I know people who have been running Lagunas in nasty/dirty outdoor ponds for many years without any problems. I admit that I have yet to clean my pump (Max-Flo 4200) and it's been running like a champ for 2+ years. But everyone's mileage may vary.

Hi John, I come in peace, to talk about pumps...
What you say also holds true for external pumps. For every story about submersibles locking up, there are plenty of stories of bad seals on external pumps and people having water damage as a result. It would be impossible to determine which pump will last longer in this thread. I know of Reeflos and Lagunas that have been running for many many years without any problems.
Unfortunately, I've had 4 Reeflo pumps (2 Hammerheads and 2 Super Dart Golds) with seals that leaked right out of the box (drip, drip, drip from where the shaft enters the impeller chamber), so I personally prefer submersibles these days...specifically, Lagunas. At least with a submersible, you don't have to replace the seals every few years and you don't risk water damage.
In regards to their efficiency, are you saying that Laguna embellishes their performance figures and Reeflo cuts themselves short?
Customer Service goes to Reeflo hands down (they treat customers right) and I've never even dealt with Laguna customer service. But the reason I know the customer service at Reeflo is awesome is because I had to deal with them for several months due to leaking pumps they had sent me. Take a guess why I have no idea whether or not Laguna's customer service is any good?
...That's right
Just to add fuel to the fire I have seem reefers running the Laguna's 100% external with 0 issues. So calling them submersible only isn't accurate...
