Kelly - one way to approach this temperature influence is to use the dye in above ground pools. Two similar small ponds at a fish farm, esp two that were filled at the same time ande the same depth, bottom shape, would have fewer variables than two ponds and possibly different ages several miles apart. Temp tests could be made and then in several days after temp tests the dye added to control pond assuming dye was to be used anyway.
