I have a 180 gallon and right now i have a ER RS180 on it.
Would a BM 200 be much of an improvement or not enough?
Read through the BM info threads, I don't think the ER RS180 can touch the BM200 in performance. In terms of built quality, the ER would be stronger, but the BM200 is adequate built as it won't break with normal use.
Would a BM250 be a huge improvement?
IMHO owning a BM200, I don't think you need a BM250. Save yourself some money if you decide on buying a BM skimmer.
What pump does the BM use?
Sicci pump, the air draw is just as strong or stronger than the Eheim 1260 needlewheel pump, but uses about 1/2 the electricity.
heard they had kinks with the BM are they worked out?
If you talk to Ed at KM Associates Int'l, I think he would say that the kinks have been worked out on the power behind the pump and matched to the skimmer body. The fine tunning and adjustment is complete on the BM250, but the BM200 could use a Deltec/ER air valve along with the new gate valve kit. From my experience with my BM200, I would agree that the lastest version is probably the best version produced to date.
Thanks guys
