Hi Everybody,
My husband is making me an indoor bubbling fountain and I would like to know if it is ok to use an air pump for the bubbles or does it need to be water?
There is a slight bubbling in the centre as the air reaches the top and hits the rocks and also a lovely bubbling sound that fills our loungeroom.
I would appreaciate any input you guys can give me.
Thank you!
