so the psk 1000 is an updated pump?
i saw that the swc had the 2500 and the ro had the 1000 rated at the same bioloads and was a little confused by this because just assuming that a 2500 is a slightly bigger pump than the 1000 but thats not the case?
lvsuckerfish- have you herd the rumors that the cone bubble kings have the dialing in issues?
Skimmy (mark) - do you agree with mike should i think about going bigger than the 180?
well, i think 1000-1200lph air injection is plenty for a 180 as long as you are running carbon, and preferable a fuge as well.
I may be upgrading my 250 SWC to a cone soon..
What would be the best SWC cone?? I would prefer one pump instead of two. I have a total of 210 gallons of water but HEAVY (soon to be heavier) bio-load
swc does have a new cone skimmer,
the new SWC 230 cone with askoll pump, 60 scfh at 50 watts, pump in the body, should be about $500 or so.

Hmm, good topic.
I have been looking for others opinion on this cone theory. I am still not sold on it being better then a straight skimmer.
My thinking is that they will actually inhibit the rising foam and narrow it down. Let me explain;
So here is this chamber with all these bubbles gathering nutrients on there surface. The bubbles are being forced up, when you restrict that upward flow the bubbles are getting more narrow in the column, some are forced up and others are now being forced down.
It is these bubbles that are being forced down and away from the collection cup that I worry about because they have a greater chance of being returned to the aquarium and carrying now with them, the nutrients we are trying so hard to remove.
im guessing u dont own a cone skimmer...
yes, they do skim better infact, and yes they tend to be more efficent.
a good cone skimmer is not going to have bubbles forced "down" the reaction chamber, that is what the bubble plate is for , to alleviate the turbulence allowing the air to travel up at a slower rate, but ultimately i think that is a moot point, because most skimmers inject process water at the bottom, the water and air moves to the top of the skimmer, then the process water has to fight all the bubbles going up to get to the exit, meaning that there is going to be more dwell in the reaction chamber, and that the water molecules are going to get caught in the air and probably travel up again a few times befor they exit. the trick is having a pump, bubble plate, reaction chamber, and neck size that all match eachother properly, so a good cone skimmer will anticipate these in the design and choosing of pump, less expensive or poorly designed cone skimmers might not consider those items so much...
