Royal-Exclusiv / Vertex Cone Skimmer Club

Wondering if my 300 is set up right - there is some swirling in the top of the neck and it doesn't seem to want to build a very stable head of foam. I don't know if the movie will help....but if you look about half way through the clip you can see that below the collection cup there is some odd looking turbulence. Can any of you other 300 users tell me if this is your experience as well? I am running it about 1/2 closed, in 10" water, a couple hundred gallons of an almost entirely SPS tank.

 
ummm by couple hundred gallons I hope you mean like 400-500 gallons.

The 300 is a beast but needs a lot of proteins to work right.
 
I am trying to decide between the vertex 300 and the SM 300. I like the smaller footprint that the alpha offers, but the chamber seems a lttle smaller (hard for me to compare cone to cylinder). Is the performance of these skimmers comparable? i have a 300g total voume system with 20 fish, 5 of which are large Tangs. I love SPS as much as I love big fat Tangs and try to keep both happy with heavy feeding and heavy skimming.

The Alpha may pull more air but, Klaus has mentioned before that the SM ofers a better design. The SM would most certainly offer more volume as well.

HTH
 
I wouldnt do the 300, the Alpha 250 maybe. I have 16 fish in a 155 with the Alpha200 and its to much skimmer for the tank.
 
I have just joined the club and bought a 170. I am having glass cut for my sump to raise the water level and from reading 9" seems to be the sweat spot for it. Dumb question , but I am calulating that my baffel need to to be around 8 3/4" tall to get a 9" level. The water will be flowing over the baffel. does that sound about right?
 
Personally I would go higher.

Its easy to raise the skimmer up a bit if you need to go with less depth, but if its not enough rebaffling sucks.
 
I debated going higher, but since i dont have a ATO yet, it should keep it pretty stupid proof. I did talk to Albert at royal and he said that 10" is recommended. I think that is too high
 
ATO should not matter. The baffling should keep the skimmer chamber at a constant lvl. Your return pump section would rise and fall in lvl based on top off.

I think you will be very dissapointed if you get the skimmer and cant get it to work right because your skimmer depth is to shallow...... I went with 10 inches myself. It was very easy to raise the skimmer up with a little egg crate material.
 
Back to my original question- What should the baffle height be to maintain a 10” level in my return section? The water will flow over the baffle so 9 and ¾?

you would think I should just put in a 10" baffle, but reading this thread says that even a 1/4" change in level will effect the performance

The first problem is that it is in 10" of water. It needs to be in 8"-9" of water. it is amazing what an inch can do. Also, I have mine on a 385 gallon system with 23 fish at the minute and it is just starting to pull a steady head of foam after 2 weeks. A "few hundred gallons" is not going to cut it.
 
I was completely shocked when I came home to see how big this monster was. AMAZING!!!!

Nope, the ports are not plugged. I have never heard of them being plugged. Should they be? If so how is it supposed to be done?
