Compressor for Aerater

[DavidD]

Great idea! It's the amount of bubbles, not the size that is important. I've heard this somewhere before .....

that is what I was thinking, not the size, but the output.

You want to maximize the total surface area of the bubbles and their contact time with the water. Smaller bubbles have a larger surface area relative to their volume and they also tend to take longer to migrate upward to the pool surface. So use the largest output (volume of air) you can but produce the smallest bubbles from that output possible for the best combination. That probably requires a type of nozzle you don't have since the smaller nozzle probably restricts the output rate. The ideal nozzle would be one that had many small nozzles to produce lots of tiny bubbles (I can hear Don Ho singing now).

If you only have a choice between a large output rate with large bubbles vs. a smaller output rate with smaller bubbles, then I agree with the earlier post that the larger output rate is probably more important.

I could see a manifold type fitting with caps on it with slits cut into them with a pencil grinder with a cut off wheel for this. I will make one sometime here, pvc should work, plus it would keep costs down.

Or maybe a few of these:

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. 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.
