The twist lock needs almost no pressure IME, his O-ring must be bad... or missing.

Mine has not leaked at all.

uhuru · #**352** 09/03/2007, 07:04 PM

no my o-ring is not missing or it would be leaking no matter how hard I twisted it - I will see if I can get a replacement o-ring though or find something that fits at HD

I used the silicone lubricant as hahn suggested and it has worked - for now at least

If I could do it over again sure I would get it. Before that I had a PM skimmer with mesh modded GenX pump on it and the DAS is superior. Build quality wise however it's not even close. Considering what HB said that his requires no pressure to seal I'm hoping that it's just an o-ring problem.

No big deal if it were in sump, but this is completely external. With the amount of torque i have to use to tighten the cup, I'm afraid I will crack or break something one day. I do not think this is a good design choice for extruded acrylic at all. Maybe it's just my particular skimmer, too much tolerance or something, but I much prefer the thumb screws and keyholes.

Good to hear about your skimate, I have the same problem with the
twist lock collection cup.

Thanks hahnmeister, i will try the silicone lubricant for faucets

I would buy again and no you don't need the mesh mod to get the milk look. right out of the box.

I have an EX-1 and about the same time I bought a AquaeuroUSA 250. The DAS is a far superior skimmer. I may try to mod the AEU into a recirc with DAS pumps but that seems like a whole lot of work compared to just buying a new EX-2 or 3.

carlos_fb · #**356** 09/03/2007, 10:02 PM

What if you just replace the rubber seal with a thicker one?

Thats no joke... considering the Aquabees are $110ish each, its just easier to buy the rest and get an EX-2 or whatever.... sell the AE250 all together.

No problems with mine yet... unless you consider 3/4 cup full of the nastiest smelling sludge ever a problem

brucem · #**359** 09/04/2007, 11:58 AM

I have a das ex3 how many gph are running through these skimmers. If gph was increased do you think it would skim wetter

Thanks

db_triggerfish · #**360** 09/04/2007, 12:36 PM

Which pump are you using on the EX-1 i know DAS recommends a turn over rate of 1.5 x tank volume per hour. Correct?? not sure.

THANKS,

hahnmeister · #**361** 09/04/2007, 09:28 PM

1.5-2x tank volume. This usually matches up with the volume of the skimmer to give the water about 30-60 seconds in the skimmer. Find the skimmer volume (radiusxradiusx3.14xheight of water in skimmerx30=minimum gph to be effective).

Is Petorama shippping DAS skimmers now?

sherm71tank · #**363** 09/04/2007, 09:49 PM

I don't like this formula. A skimmer should have a set flow through rate between point "A" and "B".

as far as I know they are, mine was shipped 1 week after I placed the order - at first they said the pumps were held up at customs, then soon after they said the pumps had arrived. This was several weeks ago.

so far so good I've dumped my 2nd cup and twisted it back on without any leaks today. seems all it needed was a little lubricant.

I would say yes, i ordered August 1 and got it August 15, but during that time the pumps were held in customs as per Petorama and Orca. Their customer service is not good. But, i think the wait is worth it.

Why not? The rate determines the exposure time.

sherm71tank · #**368** 09/05/2007, 08:14 AM

Because I see skimmers rated at 90-300 gallons. Given this rating I am to believe I can run anywhere between 135 and 450 gph with the same results. I don't believe that. I believe there will be a sweet spot where this skimmer runs and the size of tank it is on does not change that. Maybe the rating should be narrowed.

uhuru · #**369** 09/05/2007, 09:05 AM

what would you say is the sweet spot for the DAS EX1? I'm running about 150gph through it. Water level is right at the black plastic piece before the neck.

sherm71tank · #**370** 09/06/2007, 08:05 PM

I hope someone who has one can chime in. I ordered an EX-2 and they are back ordered on pumps. Don't know when I'll get it.

I have been waiting for Orca to order my EX-1 for over a month now and honestly I'm getting tired of waiting.

Does anybody know if the pumps are still in customs?

GreenUku · #**372** 09/06/2007, 10:50 PM

I'm still waiting on Orca as well.....

uhuru · #**373** 09/06/2007, 11:11 PM

this is why I'm very hesitant to have them build me a custom skimmer, I think they're just too busy - I'm sure they got some pumps just like petorama did, but maybe their waiting list was a lot longer especially since they also have to use them for their custom skimmers

sherm71tank · #**374** 09/07/2007, 06:42 AM

Petorama is suppose to get the pumps in on Monday and plan to ship out the same day.

Creetin · #**375** 09/07/2007, 07:51 AM

One tip i have found to raise scfh up is increasing the diameter of airline. Gains are there be it 1-5 scfh in what i have found on the few pumps i have tried it on. Increasing the diameter of the venturi hole is not nec, But you will need to mod it by glueing a half inch piece of a cut bic pen to it so the new airline fits snug.
Also drilling the bayonet to accept the larger ailine as well. Be carefull!! You can drill it too big and go thru the edge.
I was getting 3 scfh increase on average with this simple mod.
Very easy to test out before you make it permanent by just holding it in place and testing with flow meter.
Same principal as plumbing, The longer the run the better it is to have a bigger diameter piping.
Dont rush off and do the mod without testing first!!!
