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.![]()
