Kong, when I had the ex-2, the external pumps sucked 10lpm. I guess the head pressure from the internal skimmer is cutting down the air. It still works decent though. I just hate the design for controlling the water level inside the skimmer.

Regal, that looks like fun!!!

Wow Regal, you get two for the price of one! That thing looks like a beast. I can't wait to see it hooked up and running. Your tank is going to love it!

5lpm sounds too little for the das. There are a number of reasons why the pump is not sucking as much air as it should be.

1. clogged intake - (unlikely for you)
2. If you took apart the pump you will see a little flap. this flap ensures optimum flow with the impellar flowing in two directions. But sometimes the flap gets stuck and the performance gets reduced by a lot. Check it out.

Then come over and help me hook it up. You can see how it does first hand.

I know we are supposed to post pics of our skimmers while they are working but I just got this thing and I had to post a pic of it. I have named her Eleanor because any equipment this large should have a name I think. There is a beer bottle and my door knob in the pic for reference and it was taken at a downward angle. It's an MRC I forget the exact model I'm looking for the receipt. Waiting to setup the system she'll be attached to.

Never seen a horizontal skimmer before, does it work any different?

Looks nice, btw.

It will be tempermental like "Eleanor" in the movie , I am sorry you bought a MRC , should have gone with a Barr Aquatics for a beckett.

OMG I can't believe I just read 113 pages of this. I also ordered a DAS EX-1.

For all of you that are using DAS, Deltec, H&S or any other needlewheel using the aquabee pumps you need to know that there is a flap inside the output that will get stuck over time. If this flap gets stuck it will seriously impeded its performance. When the pump is turned off and on again the direction of the needlewheel can get reversed. If the flap does not change direction the performace goes down by as much as 50%.

I was watching a discussion with Pierce and Dave in which Dave swears his aquabee pumps draw in 10lpm and more whereas Pierce says its more like 5lpm. When I had my BX3 it performed like a champ whereas other BX3 skimmers just lagged. Check the flap as it might be the cause.

To clean soak the pump in a 20 to 1 ratio of Muriatic acid, EZclean or vinegar. Vinegar does not always work as nice though.

I took Hermans advice and cleaned the flap inside the DAS pump. The pump went from drawing 5lpm to over 10lpm using the same air meter. I don't understand how that flap makes the pump suck more air???
