sry if this been asked or solved but i kinda just skim through a few pages ..( sry.. i have dial-up... even those small avitars slow me down big time!!! ) but a few q? about that design and possible problem on your skimmer hanh....
first.. why it the inlet to the skimmer soo high up?? ( im think to have a counter current agianst the bubbles but wouldnt it be better to judt directly turn the new water into micro-bubbles right from the start asap?? like if you had the inlet right next to the recirculating pump with a '90'; directing it to the inlet of the pump)..
and about they 'on time' of the pump ... wont you loos this' break in slim' if it is off for too long.. wount it dry out some causing a lost in effciency of the skimming for the time frame??
and as for the outlet to the skimmer.. why would you need it soo high?? dont you want it like 4'' lower then it is in that pic?? just in case if you 'clone' makes crazy foam head and you need to lower the water lvl... to my understanding is that the only way you can get the water out is by force ..( like more pressure inside the skimmer then the outside causing water to flow in the directoin of less resistance..) only one thing come to mind.. a extra pump ... forcing feed water in more and faster than you might want.. but if the outlet was lower then it will still be lower then the water line and water will flow to the lesser resistance.. ( hydrostatic pressure)
ohh and when you post the pic of the new skimmer plz post in medium size pics for the dial up people like me.. you dont know how long it take to see a full size pic at 56k....
thx

what size skimmer did you decide on
<a href=showthread.php?s=&postid=9708899#post9708899 target=_blank>Originally posted</a> by hahnmeister
I would go no more than under 30" of water. This doesnt limit you much though as far as skimmer height goes. If the pumps are mounted up on the skimmer body (rather than rest on the floor with the outlets going up and over to the skimmer with an elbow)so that the air intake is at the highest possible point, you could have a 4'+ skimmer still... only the pumps arent at the bottom. Also, keep in mind that I said 30" of water... so you have another good 12" or so of foam collection cup on there. I would say that beyond 48"-54" of total skimmer height though, you will start to see the pump performance go below what its worth though.
Look at Deltec like this one...
http://www.deltecusa.us/proteinskimmers/ap1006.php
Note that the pumps are higher up on the body, with the outlet facing down to blow the bubbles down into the body further, and that the pumps are a good ways up the side of the body. The intakes from the pumps below can be used to create a nice downdraft as well. On this config, the pumps are still getting rated at 750lph... so a 25% drop in output at 42" of total skimmer height.
Here, look at this older model that Spazz did... something like 6'tall...
look at how the pumps are so high on the body, and the intakes from the pumps are down lower... and all the bubbles that are being dragged down in the skimmer body from this. There is no reason you couldnt do this with eheims (those are OR 2700s only on that skimmer) and get the same effect.
That skimmer blew out at the base. Too great of water pressre.
Well, just sent in a price quote 
.
Right now I'm aiming at getting a recirc: 16" dia. with a 32" height and 6" neck if he can get some 16" tubing. If he can't get 16" then 12" would be next. For pumps I was thinking of 4 oceanrunner 3700's or 1 Dart NW pump. Would that pump choice be too much? Other options are a body drain valve and a valve for the collection cup drain.

WOW, what tank is this going on? Do the eheim pumps with the euro-reef pin, or just mesh mod em yourself. 4 sounds about right... model it after one of the deltec models and it should rock.
double checked and i think deltec would do 5 for a 16" body but 4 for the 12", good luck! and make sure to email them seperately from the quote.

go for the dart pump.I am waiting for that model he is in the design process right now
The skimmer will be going onto my 240g. I want something that will be able to handle a tank a lot way bigger than my 240g so I wouldn't have to buy a skimmer if I ever get a bigger tank. I'm thinking the design I want could be well capable of 600 gallons easy. Hopefully the price tag will be under 750 since I don't plan on going over that price much.

Thought I would post some pics for inspiration of a lesser known protein skimmer company... with roots similar to the ORCA (a smaller company that prides itself on custom makes), but in EU. Perhaps some of you would like to get orca made versions of these skimmers (besides the others you know of already like bubbleking, bubblemaster, H&S/deltec/ER/ASM/Octo style, and those style skimmers...

Dont know where to get funnel shaped bodies like the KZ though.
The 150 is a 6" diameter mini bubbleking... its a favorite of mine in that Ferrari Red. I think it has some serious potential with a Aquabee 2000 or an eheim 1250 needlewheel (maybe 1260?)

nice pics hahn.seems they prefer that cone shaped body.Does this force the bubbles to move up(less restriction) making room for a nicer foam(less turbulence) smaller bubbles.

Could be... I think it minimizes the turbulence that the reducer area tends to make just below the neck. Problem is though... where does one get acrylic funnels like that... you know?

Hey Hahn,
Does any manufacturer offer a "Wetneck" yet?

No, just spazz. I would imagine orca could add one on custom though... its easy enough. Really just adding on the outer pipe, and a contoured top ring, and then adding the tap in between the two to plumb water in.
