Bubble Master 200 / 250 noise comparisons

[johns]

Bubble Master 200 and 250 models-

How noisy are these skimmers compared to the typical needle wheel impeller models (ER, ASM, etc)?

How about compared to one another 200 vs 250?

Much quieter to the deltecs, h and s, and euroreef's.
They are almost silent. I can hear a single aquabee over 2 sicci pumps.

The pumps are pretty quiet. However, the water outlet can be noisy with the splashing (unless you have a Gen 4 BM with the gatevalve).
