Well - a powerhead thats not submergable would be pretty useless - however
my "submergible" powerhead also has this sticker. I submerged it without a
problem.
On the route I would take .. I find that putting the tubing into the water
intake side of the powerhead results in a lot finer bubbles - and a better
PPM count - if I'm not carefull I can easily achieve 50 PPM in my 90 gallon
with 2 2L bottles using this method.

OK, I've been using an upturned bell in my 55gallon as my diffuser for
quite
some time, with 2 2L bottles of yeast solution. Well, this method works
good
and my plants are doing good, but I can't break the 15ppm mark. My goal
is
25-30, so I'm going to try something new, and today I went out and bought
an
aquaclear 201 powerhead. I also got some new, sturdier 2L rubbermaid
bottles
that will fit behind my tank, where pop bottles wouldn't. Anyways, I
don't
know what the best way to tackle the solution is. Should I:
a) Put the CO2 output into the airline input of the powerhead
b) Have the CO2 bubble into the water intake of the powerhead
c) http://www.csd.net/~cgadd/aqua/diy_reactor.htm
That reactor looks good, but if one of the simpler methods will work, of
course I'll go that route. So, what are other people's experiences?
Also, my
201 has a sticker on it that says "do not submerge" but I think that it's
actually submersible, and just not CSA approved for it. I have a heater
like this. Can someone verify that it is submersible? I don't have the
manual for it.
