Can see the difference Do you have any slap together surface skimmers? I wont let hubby put a real skimmer on the pond (he cant convince me fish wont get caught in it) Want something that can be put into the lower pond, but taken out when not in use ... have disturbed crap floating on the surface of the lower pond, from the upper pond ... My present choices are to use a fine net to skim it off by hand, or wait for it to settle, so the main pump can grab it ... Hubby doesnt have the time to make anything, and half joking told me to spend the $90 to order one of those cheap floating skimmers meant for small ponds ... trying to figure out something that *I* can handle making QUICKLY, using something like a powerhead pump (stolen idea from your filter above LOL) ... any ideas?
