I was just at my local Petsmart and they had this filter. I cannot find
anything on the net about it. It is made by Laguna and says Power Flo
underwater round filter.

The only thing close I could find to a model number is Art.# PT-1750. It
wasn't even listed on the manufactures web site.

Has anyone used one of these? I have a small 250-300 gallon pond.
