Best air pump?

I was curious... I want more oxygen for my roots. Can anyone suggest a reliable and very effective air pump that produces lots and lots of bubbles?

rez size?

1 watt per gallon

i have 8 gallon rez with 9 watts

I am using 2x 5 gallon buckets. i was thinking about the dual diaphram pump from bghydro.

the pump produces air..the stones produce the bubbles..you want the right airstone to make the best bubbles...az

I didnt even think about that. Well my walmart stones are producing very small bubbles and they have worked for awhile now, but i was just seein if anybody had any better recomendations.

lol best pump or stone lol

well if stones you need then go with these


Ceramic Air stone

I'm using the same stones (from wallyworld) and agree they don't seem to really "bubble" I'm thinking of trying a bubbler hose section with a fitting on the ends to allow a 1/4 hose connection for the air pump should allow more bubbles?! just an idea that I'm still trying to find parts for .. maybe that will give you an idea as well... whoever gets it working first let the other know ? i'm just on wk two of my first hydro grow as well.. I started 6 AK48s a wk ago friday will post pics on fri .good luck..
