I do a few fountains, nothing special just skim the schmeg and toss in some shock every now and then. I have this one fountain that gets dishsoaped once a month - six weeks. I try to keep the area super clean, not even cigarette butts but the bratty kids have @ it now and then. Keeping up on trash flow really helps to reduce vandalism, what do other people do and do others have these crisis also? Any funny stories?
