These cute tropical fish are the quick, easy way to keep your pool warmer this season – even while you are swimming. Just snip the fin, toss the fish in the pool, and the revolutionary liquid solar blanket inside rises to the surface. This invisible layer on your pool's surface inhibits heat evaporation with about 60% the effectiveness of conventional plastic solar blankets – but its 100% trouble-free! Best of all, the liquid solar blanket works 24 hours a day; and it is completely harmless to skin contact and all pool surfaces, and will not adversely affect your water chemistry. One fish covers 350 to 400 sq. ft. of surface area and will last up to 30 days. 3 fish per pkg.
