So I've been reading for the last 2 weeks and I can't handle it anymore:hmm4:. Would like some help with picking out a skimmer that would be sized correct. The whole system would be around 220-240gal. I have been looking at the BK SM200 or 250 and a used alpha 200. I'm open for suggestions too.

TIA

You say the system will be 220-240Gal.. How big is the display and what kind of stock are you planning in it? You really should base the skimmer size on the display and not the overall volume since the load is typically concentrated in the display where as the rest of the system (sump and or refugium) contributes to nutrient export.. As such, with a bit more information, it will be easier to provide better suggestions.. The SM250 is going to be too large for your system. I run an SM250 on my heavily stocked 600+ gal system that has a 480g display. I also think the SM200 may be a bit oversized as well. These skimmers have fairly large neck diameters. If you go too big with these skimmers, they will end up being inconsistent as a result. They will skim great at first but then idle along until the dissolved organics build back up enough to produce a decent foam head. The end result is having to run them on the wet side to get any consistency out of them. If you go too large, you will be disappointed. If you properly size the skimmers to the display and load, they are by far the most consistent foam making, skimmate making machines. You are much better off with a properly sized skimmer that works consistently hard vs an oversized skimmer that hardly works and isn't consistent.

If it were me, I'd avoid the Alpha and lean towards the Bubble King Double Cone 200 but without knowing more about your display size and stocking, it's really difficult to be certain.

I really appreciate your time.

The DT is 185 gal with either a 80 or 60 gal sump. It will be stocked with 95% sps and loaded with anthias. I figured that I would be feeding a lot thats why I was looking at at a bigger skimmer. But yes, I do want a skimmer that will be consistent.

At first I thought of reusing the omega 150 that I got from Jason but its under sized for the new setup.

Glad to help. Get the Double Cone 200. That will be your best choice for a system that size (in my opinion) and will be very consistent. It's actually perfect for you size tank. Especially if you keep it well fed. You will love the RD3 speedy pump too.

They look like the omega series. I'll do some research on the double cone 200.

Thank you!

They may look similar in terms of the exterior body design but they are vastly different. Not even in close. Aside from the pumps being completely different, the Omega 200 has the pump inside the body. I don't think they even make one with the pump outside the body in that size. The BK has a larger diameter body and much better contact time not only due to the body size and design but also by virtue of having the pump external to the simmer body.The BK RD3 pump is far superior to the Askill based block in the Omega and allows for much easier and finer tuning as well. The overall build quality of the BK is also far far superior. The BK will be much easier to maintain too. You don't need to tear the skimmer apart to service/clean the pump. You remember the old Ferrari Testarossa or Lamborghini Countache conversions that were based on the Pontiac Fiero's?? LOL.. They may look similar to a Testarossa but that's were it ends....
