Bubble King new improved design?

I have hear something about new design of Bubble King skimmers?

Can anyone tell us what is changed or improved?

I think Alexander already have newer version.. I see much more holes in internal bubble chamber....?

Dejan... sorry for the hijack, I hope I'm on the short list.

Madison... Did they put the wrong shipping label on that skimmer?

Man i wish i had the money for a BK.I'm sure i'll be happy with my new Deltec.
Maybe in a year or 2 i'll get one

[OUinLA]

Wow, word spreads fast.

Dejan, i'm not sure which model you have. Do you have any pics of it? When did you get it.

Yes Steve, the skimmer was sent to the wrong address. LOL

[OUinLA]

But the improvements are just as you pointed out, with more injection holes. then I was also referring to the different needlewheel that US customers might be using after we test it a little bit.

Sounds about right.

Madison... remember I have your address. Better keep it under your pillow at night.

After examining pics of BK from different sources I found only this modification. On RC posts most pics from Heinz are with much less injection holes.

What is the difference on impeller? Maybe Alexander could answer this..

As I see Klaus can not answer because he did not answer nothing on threat about delivery time..

[OUinLA]

The difference in impellers is size, which affects the amount of air/water. Because the US uses a different hertz cycle than Europe (and most of the world) Klaus is not able to test these pumps with the US frequencies. Because of that, we are trying his normal impellar and a smaller one to see if one works better than the other for the US skimmers.

So,


Now that it is here, Do You like????????

[OUinLA]

John, I wasn't kidding when I said it was deliverd to the wrong address. Steve was making a joke, but I wasn't. Klaus filled out the shipping label just fine but I think the German freight company entered Gary's address as the "ship to" address because of the invoice (Captive Oceans) that has to accompany international shipments. I will have the skimmer tomorrow

[John Brancheau]

Yep, I forgot Gary said it was shipped to him........

Hi Dejan, as much I know my skimmer was equipped with a second “holed” disk in the skimmer chamber to lower the turbulences. Also the water inlet of my skimmer was modified, because I have ordered it in this way. Normally the connector for the feeding pump in the external models is placed at the side of the ground plate. The connector of my skimmer is placed on the ground plate because I had not enough space for the “standard” version. This modification does not has any impact to the skimmer.

Klaus also told there where some modifications since the skimmer is available:

Probably you have a T part pipe on water inlet? I think your AquaBee 2000/1 pump do not push enough water into skimmer... that is why rest of water should come from skimmer as recirculation?

Round plate with more holes in bubble chamber should reduce turbulences, however some authors rather prefer more turbulent water movement to get better water/air bubble contact (and longest contact time) than less turbulent water movement in skimmer body.

As H&S, Grotech and Deltec in their skimmers push air-bubbles/water mix directly into skimmer body without any chamber for changing water movement more or less holes on round plate should not significantly affect skimming and producing foam.

But on other hand you wrote BK is much more effective than your old H&S skimmer? Is this caused only becouse better pump on skimmer or also as result of different construction of skimmer?
What do you think?

[G.Alexander]

Dejan, no T-part as pump connector, just the regular connector coming with all the external BK installed at another place (upper side of ground plate).

Water quantity circulating through a skimmer in my opinion is a question of faith. In my opinion less water exchange with the skimmer will calm down turbulences which will bring better results in skimming. I am talking here for example of a difference 2000 vs. 6000 liters per hour. Water exchange should be dimensioned to the maximum causing arguable turbulences in the skimmer camber.

The real improvement changing from the H & S to the BK was the doubled air quantity which is soaked in by the pump, also the consistence of the bubbles.

You should take picture of that part of your skimmer... As I look on your pics I can not see that section.

You use AquaBee 2000/1 which is rated around 2000L/h pump? So each hour you put only 2000L external flow true skimmer? OK but what about the pump? If this is only water which is going into the pump then where is others 4000L?
As I understand BK produce so much and so small bubbles that they do not flow upward to rising tube to form a foam, therefore pump had to push them
up.. and therefore turbulence is better be small or none..

I think you did not measure air quantity on your old H&S skimmer.
The real improvement is in huge power down use, much better performance and also quiet working.... all together much better and efficiently skimming..
