Using it like Old Scales says may work in some cases where you can really scrunch it up good ........ but it is definitely NOT a polishing pad. The polishing pads I buy for my Fluval C series HOB
's are 100 micron Aquatic-Life non-woven ........ VERY VERY dense and only 1/12th of an inch thick and they work great yielding very highly polished crystal clear water.
I have two bags of the Rite-Size stuff that DrsFoster & Smith sent me by mistake on one of my orders and rather than send it back they told me to just keep it. I can find no use for the stuff that's 3/4" thick. I wish I could find someone who could use it close-by !!!!!!!
HMMMMMMMM .... Maybe it'll work in the filter for the new pond we are putting in the back yard !!!!!!!!!!!
