Just wondering. Some old books on aquariums have airstones in use, just wondered if anyone still had a use for them. I have one in my QT tank just to move water around when I do huge PWC
and the power filter is out of the water. I did notice the fizzy spray that puts a salty mist in the area around the stone. I thought I may help release any trapped gasses from fish waste or someting.
Thanks again and may you all receive huge gift certificates to your favorite LFS
( if your into X Mas that is)
