injecting extra air into a beckett?

[capt. insano]

thought I might post this here also to see if any of the DIY gurus know:

one of the airsupply lines for my dual beckett MRC became clogged the other day, so I simply started blowing on the end of the line. Not only did this action free the clog, but with prolonged blowing, I noticed that the foam head in the skimmer increased dramatically.

I am driving a dual beckett mr3 with a pcx-70 pump. Does a pretty decent job.....but, would there be any benefits to hooking up a really large air pump to push extra air thru the becketts?? Any potential drawbacks? (besides the extra watts to run the airpump)

In my experience you need to somewhat restrict the amount of air into the beckett to get the smaller bubbles desired. If I forced air into my beckett encloure or even just left it's valve full open I would get a larger volume of bubbles but they would be large bubbles and wouldn't work as well at pulling out gunk.

If you are still getting tiny bubbles while injecting air it would lead me to think you still have a clog in there or the hole letting air into the beckett encloure is too small.
