btw are smaller or larger bubbles more desirable?

Okay guys, To get the best performance the water level have to be here:
That is with you skimmer pumps OFF and just your feed pump/overflow running.
Once you set it the way you like you shouldn't have to mess with it again.

if you look back at my post on the last page it shows you the correct level.

Probably so but obviously the amount of water being pumped into the skimmer is going to affect the water level height in the skimmer. DAS places the stock output T at a height where they feel that a range of appropriate flow rates for the skimmer can be dialed in with the ball valve on the input, in combination with air flow adjustment, to adjust the skimmer for good skimmate production.
No problem, please ask all the question you have!!
I set the water level first then use the air valve to adjust how i like to skim. The more air the "wetter" you will skim.
Also the water flow effect how much counter-current flow is in the skimmer. This is why i never saw the need to add a gate valve.

Well, I'm going to have to mod mine with an expansion coupler to get the water level lower so I can run the water and air full open with no valves or restriction. As it is stock I have a MJ 1200 Feed pump that is throttled back a bit with the input valve and the air valves installed but open which still restricts the air some. I cut an inch off the expansion coupler to give me more room to play with. I feel this will give me optimum water and air flow for this skimmer.
Edit: I opted to not use the expansion coupler and just used a 1" union. I cut about 1" out of the outlet riser assembly to lower the water level.

You dont need the gate valve but you definitely gain more flexibility with one. Or, an expansion coupler instead. Without a valve on the outflow you are basically flowing the same amount of water through the skimmer no matter the size of the aquarium, with all else being equal of course. Personally, I think the lack of the valve is a money saving choice by DAS. It does add something else to have to fiddle with but not really because you are just adding another way to set the water level. It simply allows me to run whatever quantity of water through the skimmer that I want to, within limits of course. To me, flexibility and options are never a bad thing especially when it only cost the price of a gate valve.
I decided to start out running 2X the systems volume per hour through the skimmer. I can easily do that by measuring flow out the skimmer and adjusting it to 2X per hour with a gate valve on the pumps output (or the skimmers input ball valve). From there, I just use the output gate valve that I added to set water level for my chosen 2X GPH. If I want to run 1.5X or 1X or whatever X, I can do that. You dont have that flexibility without a valve on the output.

I am sure that Petorama has their own stock..
yes but no... I order mine though petorama and the order went right to DAS. Which it took 3 weeks and and no skimmer so I called petorama the retail store and talk to a manager there. They only have stock for walk in only. Thats why I had to pay more for mine (TAX) and they sell for more at the store. He canceled the order to DAS. It's realy messed up how they work... But petorama doesn't even know when ppl order skimmers...
The valve has nothing to do with saving money by DAS.
Looks at the similar design skimmers:
Deltec APF600
H&S Axxx-2001 line of skimmers:
These skimmers are design to run with a certain amount of water being pump into them. If a gate valve was needed to improve performance then deltec or H&S would used them.
With the correct flow the water is set at the right level. For the ex-2 the mj1200 wide open set the water level correctly.
Honestly i don;t feel any performance mods are needed to these skimmers. For the body size you are really at the limit of air. You will not find any other skimmer of the same body size pushing this much air through.
I really think a lot of people in this thread are used to buying skimmer that do need to be modded to perform well. For example the people who mesh mod these pumps just to have the skimmer overflow.
Pet O Rama online has NOTHING to do with Pet O Rama the walk in retail stores. They are all owned by the same company but when you order from the online Pet O Rama you are actually ordering from the DAS warehouse, NOT the Pet O Rama retail brick and mortars. DAS had problems with getting the skimmers a little while back but I have heard that there is plenty of stock now and they are not having backorder problems. People who have had problems in the past with waiting on skimmers telling their stories are the reason why everybody still assumes that they cant get a DAS skimmer for weeks or months. There are several of us now who have ordered direct from pet o rama online (DAS) and gotten our skimmers within days.
I hope that everyone on RC who is wanting a DAS skimmer finds the end of this thread so that they can read that they are readily available at this time by ordering from pet o rama online. I wish I did before buying an Octopus skimmer first because I thought I'd wait forever for a DAS. I feel for the people who had trouble getting these skimmers in the past. It really sucks to wait for something with no info on when you will receive it. But I am really impresssed with this skimmer and it has only been 5 days. I hope that they can keep stock now at DAS / Pet O rama online. Even with the price increase these are excellent skimmers and a great value, relatively speaking of course.

I dont consider a gate valve on the output to be a performance mod per se. It just expands the flexibility by allowing me to vary the flow rate through the skimmer. It really doesnt matter what H&S and Deltec does with the output of their skimmers. A skimmer is not optimized in terms of turnover rate for a 100 gallon aquarium and a 250 gallon aquarium at the same time. If, for example, 1.5X the volume of the tank per hour is the best turnover rate, you cannot achieve that on different volume systems without a valve on the output.
So, does it matter whether the turnover is 1X, 1.5X or 2X? probably not.
Does it help that I can adjust for whichever of those turnover rates I want to by valving the output? maybe not
Does it hurt that I can do so? Definitely not.
