Hey Salinda,
I remember looking into those solar fish when I was researching pool solar & they popped up in the results. Isn't there a potential issue with residue or deposits that may result from using the solar fish? OK, I just searched on it again & here it is...
From PoolCenter's page on the Fish:
"TROPICAL FISH TM Liquid Solar Blanket ~ If the pool temperature is below 21o (70o) or there is too much Liquid Blanket in the pool, you may see a white residue, because the active ingredient has not dispersed evenly over the pool surface. This will go away by itself as the Liquid Blanket biodegrades over a few days and is not a problem. "

Does this fit your situation?
