kp, i would recommend the second one from GH. it's got dual diaphragms, which is a plus. the piston driven one will be loud as fuck!!!!!

jp, do you think it will run 12 giant airstones? that's my dilemma; i want one air pump to do it all

if you purchased another gangway valve, i'm sure it would do the trick. would it be as powerful to each air stone as the other unit, probably not. if you're not really so much concerned with the stealthiness factor, the first one would probably be the better bet as it's more powerful. and it should be for $95 
i realize this is a direct contradiction of my last post, but i was thinking in terms of my own operation. to me, the quieter unit would be a better buy, seeing as how it's cheaper and has a 30 day return policy. (which is usually about when bad pumps turn to shit) decisions decisions.....

i've spoken to a friend who just got one of the 112w last week; he said it's very quiet, so that's good... also, rebuilds for it are just 1.50!
and i did the math, and the bigger one would deliver 137.5 gph of air per air stone. i think i'm going to go with it
thanx johnny

Did someone say math? This is all getting to technical for me now. I think I'll just sit back and wait for the bud shots.
When i grow dwc I only use one formula. Lots of bubbles = Lots of bud.

lol, here is the mathematical formula for "lotsa bubbles"
single outlet pump at 110 liters per minute
that's 6600 liters per hour.
divided by 4, gives you gph; 1650gph single outlet.
12 outlet/airstones; 1650/12= 137.5gph per stone

You wouldn't believe how many numbers I have swimming around in my head at the moment. Even looking at your figures actually hurts my head. I trust you though, so I'll take your word for it that you are doing everything brilliantly.

Ah, now there's an equation I can understand. You truly are an asset to the site, kp.

Be careful of the sensizym. The guy in my grow shop did a test on it and it came last, against others like cannazym (only one I remember as it performed the best). So I've switched to cannazym now. Still use advanced range on everything else, although I also prefer superthrive to B52.
Don't get me wrong, sensizym is an excellent product, it's just that it's shipped from Canada to my country. Maybe left in containers for too long or something, so you guys might be ok as you live right next door.
