Here's another dumb question (from a newbie) but i was wondering, ... before i dig my ideal 6000 gallon pond, .... if i was to put, say, four pond-designated lights strategically located on the sides, and perhaps one on the bottom, ... would these lights heat up the pond to any significance, ... if one was to leave them on by accident all night long?

Also, ...Does anybody else have pond lighting and wish they would put more than one light, ... or wish they woulda put alternating colors of pond lights (for dramatic effects), ... or things like that...?
