H&S Skimmer Club

ReefSalt, that's also been my thinking on it. The H&S puts the bubbles higher up where they need to be. I'm sure other folks have had experience with both brands, but I still believe they're virtually the same performance wise.

thedigitalimager,

Thats it ,both of these Skimmers are top notch and you can not go wrong with either ,but I personally found here in Canada that H&S are better priced giving it the advantage over the Deltec.

Okay, so you guys think the consentration of bubbles at the top of the skimmer body give more contact time huh?

My take is that when the camber is full, there is more contact time. The bubbles will rise up through the body and as a result, will experince more contact with water.

I do agree, both are great skimmers, I'm just a bit confused. I am very impressed with the a200-2x1260, but after seeing the the smaller units, it's a tough call. I was planning on upgrading to a 2 pump skimmer for my FOWLR, but due to size issues, I'm going to have to wait unitll I completely upgrade my system. However, I am going to buy a new skimmer for my smaller reef and the a150 and Deltec apf600 are the only two candidates. The problem is that with the deltec I get a full chamber for $200 bucks more, and with the H&S I save $200 but get a half full chamber. I'm stuck.

It is no doubt in my mind H&S is a good skimmer but if i had a 26" skimmer and only utilaze 18"out of the skimmer, I will make the skimmer shorter or move the pump lower or use some L to push the water/ bubbles lower in the skimmer body.
Now i saw a 200- 2 X 1260 H&S and that one was full of bubbles if they can do it on that one skimmer i'm sure they can do it in all there skimmers. I will understand if the skimmer was 39" height and if you don't like to but any bubbles in the tank that will be a good thing but on this small H&S skimmer you need to use every little space so you can get the most out of the skimmer . I"M just

jmdogg187, sure contact time is important. But how much is required? You'd have to be an expert in fluid dynamics to know for certain. In my current H&S, the bubbles coming out of the pump swirl around the chamber for a significant amount of time. I personally don't think it's an issue. I think that Fliger has run H&S, Deltec, and Bubble King skimmers. Maybe he'll have something to say. Then again, a lot will depend on which models are being compared. For me the proofs in the pudding, and my water has never been clearer.

 

[Jim_S]

Yeah, I mentoined a few posts back about adding a 45 elbow. has anyone tried this? I would really like to see what it looks like.

Am I correct by reading here that these types of skimmers have no adjustment for wet or dry skimmet?

 

[thedigitalimager]

No, that is not correct. The H&S skimmers use a "wedge pipe" to adjust the water level in the skimmer. The air is adjusted with a tube clamp on the air intake. It's very easy to adjust between dry and wet skimming.

Thanks for info. I spoke with Fliger via pm last week and he explained that certain models are better then others. For example, in his experience he feels the a200-2x1260 is a better unit then the 702, but the smaller Deltecs are better units then the smaller H&S skimmers.

One more question, can you rotate the return on the a150-1x2001, or does it have to face the same position? Thanks.

I think its a few things - Deltec uses angled returns that point the bubbles downward. Also, Deltec uses air valves that slightly restrict the air when run wide open (12 o'clock). On 1260's - its strange - when you restrict the air, the body "appears" more full, especially in pictures, while air decreases (I use an air flow meter). I don't know if its because when you restrict air, more water passes through creating more turbulence, I've also read that when you restrict 1260's - wattage actually increases so maybe the impellar spins faster. But on Deltec and H&S, taking the taps off will create a tighter body of bubbles that won't fill the chamber entirely. Which way is better, I think is splitting hairs.

When I took the taps off the 702 air intake increased, but the skimmer body is less full, right about half. Same thing happened with the 3x1260 A300. I noticed on difference in skimming on either brand, but I'm also way overskimming. The 2x1260 A200 was entirely full no matter how you ran it (this, and the BK were my favorite skimmers). So what's better - less air that spreads thru the body or more air that stays tighter? I guess its up to each user and their bioload. I've heard from a few people that they can't run an 851 without the tap, it overpowers the skimmer. Which seems really strange since I know a 701 user that runs it without the tap.

One other nice part about the bubble remaing higher - zero microbubbles. I have cut down microbubbles entirely since I took the taps off the 702.

As for the angled returns, I believe Brian is getting some in just to play with them.

jacmyoung - H&S uses a "wedge pipe" the same as Bubble King. It is easier to adjust (for me), the ball valve is hard to "fine tune". The wedge pipes that H&S and BK use are a breeze to turn a fraction of a centimeter. For the purpose of fine tuning wet or dry, I have found H&S easier to adjust - because of the wedge pipe, and also because H&S and BK use a clear acrylic neck where Deltec uses black ABS. But once its tuned to where you want it, they're equal performers so I wouldn't necessarily say one is better than the other - just a little easier to manipulate.

Jim, if you're referring to the return to tank, yes; that can be rotated any way you need it to face.

Honestly, I dunno. I "think" for the most part the equivalents are probably the same, splitting hairs. NAGA has used both and feels pretty similar. I always like my friend's APF600, it looks really nice. But then I've seen so many A150's on amazing high end European and Asian tanks its hard to say. I've only used the A110, not the A150.

I'm having a 1x1260 custom made, trying to figure out exact dimensions with Brian right now. It will be about 4-6" shorter than the standard A200. I'm sure I could get away with a 1x2001 but like most of us, we are ridiculous when it comes to overskimming so performance between the two brands is entirely irrelevant anyway. I think the performance difference is probably so tiny if any at all, and unless you're pushing the upper end of the skimmer's capacity - it won't matter anyway. Know what I mean? :lol:

OK, its like 80 degrees outside right now so I'm gonna go hit some golf balls.

 

[blgreef]

here is a thought since the amoutn of air the pump pulls in is related to the water flow, if the pumps input is below the bublles it will pull more water and hence more air.

Now get the bubles to fill most of the skimmer and the pump now start sucking in air from the skimmer and hence less water and i would assume less external air.

So is it such a good thing to have the whole skimmer body full, or bubles near the pump intake on the external units?

A110-2000

The setup is a little unconventional but it works well and there are very little microbubbles in the main tank.

feed pump is in the main tank (mini-jet 606) and the return line goes into a AC70 shell (with some carbon/phosban) and then back into the main tank.

Impressive, I am considering this model for my new 55 gallon frag tank I am setting up. Bubble production looks real impressive. Did you have to adjust the air flow or is that wide open?

 

[pili]

I closed the pinch valve slightly. Even though i got more bubbles with it all the way open, they didnt rise as well as when it was slightly closed.

The skimmer has only been running for about 7 hours though now so i am sure i will still need to do some adjusting.

As always one more H&S skimmer with only half the skimmer full of bubbles, why is that ? is that waist of skimmer space?
I understand you don't need to go to far down but look at it the bubbles only goes to the top collar . they are very nice skimmers but this is the only thing i don't understand about them.

Like i said before, i think that its all about how you adjust it... maybe there is no problem with the 2 pumps skimmer, but i also have the one pump and its not half bubbles... just play a bit with it and its going to work like a charm

Here's a picture of it when i first installed... Once its set you dont have to touch it again. The skimmate is not dark for the result of playing with it too much and got overflood in the cup

i just clean the collection cup, so here's another pictures of the bubbles...

 

[HappyReefer2]

General question for H&S owners. What are several feeding pump suggestions for the A150-F2001 skimmer? Was thinking about getting the Maxi-Jet 1200, but wanted to see what else is recommended.

 

[i2ik]

right now mine is feed by the overflow but base on your tank size, i would go for a MJ600 or 900 depending on how high its have to lift the water, i think it would be good. No matter what pump you take, it should work without problem

That is the way suppose to look .
But i saw many H/S skimmer with only half full with bubbles maybe just users error.
