Large Airpump Driver Skimmer

hmmm, well my bottom chamber in the skimmer is 12" dia, ithe air pump i am running is 65lpm and right now i am only using maybe 1/3 of that. so should i get 2 of the ALR230 or 2-3 of the ALR150

Thanks
Tim
 
Let's get this thread to the top again. Any progress reports?

It seems that if the airstone port/manifold were to leak, there would be a big problem. How about running the tubes down the inside? Would that likely mess up the bubble column? G1
 
Well it is still working like a champ. Why would it leak goby? If you were to make the tubes run down the inside on this design it would be very difficult to remove the stones and service them. I don't forsee any reason that it would leak, it is built to last. I think that we are going to get a wetneck of some sort in there soon. Last time todd cleaned it the build up in the neck was 1/2" thick.
 
It seems that having the tubes go down inside would facilitate changing/servicing the stones... you could just pull them up with the airline. With the manifold on this thread's main skimmer, you have to drain the skimmer, right? G1
 
How are you going to provide a way to hang that many airstones off of a manifold and keep it in position and rigid... and provide for a way to pull it up to service it? The small ID rigid airline is to flimsly and larger pipe would take up to much room. You wold need a step ladder and 18 foot cielings to pull those out on rigid airline.

Draining the skimmer is a easy as...well draining the skimmer. I don't see a leaking problem with this design any more than I see a leaking problem with an acces panel on anything else. It looks designed well and has a gasket.

I've been thinking about this problem for a larger diameter PVC CC skimmer that I'm designing. What I will probably end up doing is making the top 1/2 of the airline inside the skimmer out of Spa Flex and the other 1/2 ridgid PVC. This way the airline will remain in place and you wont need 18' ceilings to service the skimmer.
 
Here are a couple new shots of the skimmer. It is no problem to drain the skimmer. If he would have wanted it as a external skimmer we would have just put a drain on it to make it easy to pump it all back into the sump. The only thing about it is, is you have to have a very large sump to accomodate it when drained lol since it holds 29 gallons.

The skimmate that comes out of this thing is just disgusting funk.

I think I see Elvis. It's got to be the king.

Enter the real Bubble King. :)

Probably need a Military issue gas mask for cleaning time. Have the Nuke engineers build you a decontamination room to remove ambient skimmate so you don't wipe out the family after cleanings. ;)

Hey bigt that thing is sick. I really love my airpump skimmer as well. if you have the space it is a great way to go. I started throwing ozone into mine this week and it is pully even more crazy junk. nothing like 2' of solid 6" diameter foam.

I run a 1/2 rigid airline down mine to feed the stones and my maifold looks like this one. I went through the wall with a uniseal and then a small 90 on the inside and then to the rigid airline.

here is my skimmer build.

it is not nearly as pretty as bigt's but I scavenged parts off of my old becket.

Mark have you given up on the beckett?

Nope. I'm about to buy 20' of 12" PVC to make three different types of skimmers (CC, needle wheel using a Sequence Hammerhead and quad-Beckett) and a very large calcium reactor.

You may be depressed if you find that the power hungry beckett is matched in performance by a monster CC

Bean

Not at all. These are test skimmers. I fully expect to see differences. I expect that the CC skimmer will be the most efficient, followed by the needle wheel, followed by the Beckett.
 
just looking at that; what made you make the next so long? if it was shorter wouldnt you have less problems with the skimmate in the neck? or if you raised the water level?

just curious, I want to do a similair idea, but that neck looks like itd be hell to clean. I dont mind skimming pretty wet. Id rather it for the sake of cleanliness.
