Compressor for Aerater

very nice... I assume the barbed fittings have Female Pipe Thread?

Dunno, but I think they have other models that do have pipe threads. I use one of their smallest stones in a 90 gallon planted aquarum to disperse compressed CO2 into the aquarium.

After doing the alkalinity lowering trick learned here, and already knowing that plants don't 'like' high alkalinity, I let the chlorine in the pool run low and then put pool water in my planted aquarium. :eek: Removed the fish first and used a chlorine neutralizer too...

So far there's been a positive response from the plants.

The fish is still alive too. :D

The compressor I have is farly loud but I have 150 feet of hose so I put it in the back garage. I live in somewhat of a rural area so neighbors arent a problem. I have a 15 gallon coleman compressor it would run about one minute on 3 minutes off.

I waded around in the pool with it pulling it by the hose just off the bottom and it stayed on the bottom and didnt float when I left it in one spot.

I thought of making a atomizer for the end which would be just a empty bleach bottle filled with tiny holes and something to hold it down if needed. I have an AG pool 27 footer so I dont want bricks of metal harming the liner. In total it ran for about six hours I left the cover off tonight and will test ph in the morning.

More to follow

I measured my ph this morning it went up from 7.0 to 7.4 so that tells me if I want to run a compressor for a longer period of time my results can only improve.

Are you having any issues with oil from the compressor? I know my compressor does kick a little oil in to the air lines.

Chris,

Just keep in mind that you will outgas more CO2 faster at lower pH and the effect is dramatic. About a doubling of the rate when operating at a 0.3 lower pH (see CO2 Chart and CO2 Graph.

So you'll want to follow Ben's procedure and continually add acid to keep your pH down. You'll find your alkalinity dropping at a good clip. I know you were probably just testing the system, but my point is that you would rise from 7.0 to 7.1 faster than from 7.3 to 7.4, etc. so you can really only determine the efficiency of your nozzle designs at a given pH.

Anyway, it sounds like you've found a great design!

Thanks for the info Richard. Steve its a just a coleman 110 volt 15 gallon oil less compressor.
