Just wondering how high off the bottom the air disk should be set off the bottom of the pond? I did have it set at about 10"s and over time each year the weight sinks into the clay bottom till the disk is only and inch or two off the mud bottom.

I am going to extend the disk 2 feet up from where it is currently. Wondering if this will be enough to help keep the clay particles from mixing when the air is on?

Cheers Don.
