dont know if if does anything...but...

Thread nomination

you many not be able to see the thread...because of the way that forum is set up.

gobygoby, I got a "you do not have permission to access this page..." message on that link.

Bill, I couldn't find a picture of a dual RD BK. But it might be a moot point anyways because I did find some pictures of a 3 RD BK and all of the pump outlets are oriented in a way that would cause all of the flow streams to collide in the center. Here is the thread with the pics right in the first post. You may have to subscribe to that forum to see the pics. Sorry, I didn't want to post the pics directly here since they are not my property.

You just link right to the pic from here. I don't think that linking constitutes stealing.

(Picture removed- Some consider it stealing. It's taking their bandwidth without acknowledgement.)

Travis...good link. That thing is a monster but I am not convinced that the flows collide. Doesn't it look more like the flows bounce off a center tube? There appears to be a center tube I am guessing of about 6" diameter that forces the air and water to mix rather than crash in the center. Anyone see that differently?

BTW, I find it strange that the BK's are a the top-end and seem to use some very temporary connections like hose clamps and even many tube connections with no clamps at all. I wonder how the integrity of these connections is?

That's the way I see it too. All the flow hit's that center piece and is forced around it to mix.

 

[Travis]

It looks like I might need to get my eyes checked.:lol: I didn't see that center tube. I know how the dual pump models are positioned but I can't find a pic right now for the life of me. Basically if you take the picture above, and remove the pump closest to you and look at the 2 remaining pumps... that is how they are positioned on the dual pump models.

Take a close look at this pic:

oops...I think I misunderstood your post Travis...please excuse the extra pic!

Based on my experience, I am really not sure what benefit the center tube gives but I am sure Scott or Bill could answer that. My skimmer is a "free-for-all" in the main chamber. Stuff gets buffeted around in there like a blender and i can watch the same bubble for more than a minute go up and down...

Heres the base of the new skimmer . It will be using two nw dart pumps .

Looks like those last 4 outside rows of holes are out of alignment. can you go ahead and redo it?
Thanks

and then you can send me your blemmed skimmer!

To me, it looks like the pump outlets are above the chamber with the tube you guys are talking about. Looks like the outlet streams just collide together.

All th eholes on th eplate are right , I keep ;ooking at it diffrent ways and it looks diffrent everytime . Weird .Its just neat to look at .
I also thought about putting in a peice of round acrtlic to prevent the bubbles from crashing ito each other . I made to bubble plate removable so i could try diffrent things inside . That was Spazzs idea.
I might also try some 45 degree elbows on the pipes to make it swirle .

Got the pipes and valves today , ALl nice grey schedule 80 .Should have some of this don tonight .

I have a question about the Bubble King's plumbing. I realize the pumps push water into the skimmer body similar to the Euro-Reef & ASM. The venturi has a filter of some kind apparently too. In the last few pictures, water is forced out through the plumbing from the base of the skimmer due to downward (gravity) pressure, and out the riser tubes that surely are adjustable like my Euro-Reef.

However, the BK-on-a-box has plumbing going under the base and then back up. Why is that?

 

[Travis]

Marc, you are correct. And the outlet tubes are adjustable wedge pipes, just like what H&S uses.

The "BK on a box" is the external recirculating model. There are 2 holes on the bottom where water goes to exit the skimmer through the 2 drains (all of the external recirculating models have 2 drains). There is then a third hole that the water goes through to recirculate back through the Red Dragon pump.

 

[MarkS]

Bill, what is going to keep that diffuser plate in place? The air pressure will be more than enough to dislodge it.

 

[Bill Wann]

Ther is a peice of 1 od acrylic rod glued to the bottom and a wingnut threaded to the top to hold the plate on .

This thread needs to be considered for thread of the month for sure.

I will pass the info along

 

[melev]

I see. Hmm. Seems kind of wierd, but unique as well.

 

[spazz]

ok bill i have one concern to voice on the bottom box. how can you clean it with no access plate in the bottom of the box? i have a dumb idea to solve that problem. 1 big clear twist lock with out the center hole cut out. if you cut the hole in the bottom of the plate and glued in the twist lock and then had the acrylic rod atached to the center of the twist lock star it would seal the defuser chamber so the bubbles wouldnt escape the defuser plate, and it would give you a clean out hole for cleaning out and build up of detrus incase it settles out in the box. the reason i recomend this is because i read the bubble king is hard to clean under the defuser plates. well this would be alot like that. other than that i think its a revilutionary design. and will be copied by many diyers out there. well everything but the size of the main chamber. ha ha ha
