How could you adapt this for a swimming pool...? I have a salt/chlorine generator and the side effect is that you constantly need to add acid to keep the ph correct...

Seems like you would need to keep the flow very low - as you would want like 1/2 gallon per 5 or 6 hours max to be added...

Lots of people are facing this issue as salt generators are the hot thing for new pools -- much lower maintenance etc -- but this would be one step even better!!!

Great idea...!!!
