GIGGETY-GIGGETY!!
i use the blue tint in summer because the blue tinted water helps reflect the heat of the sun and keep my ponds water cooler because i am in full sun 10+ hours a day. in the peak of summer longer still and my pond is not even 30" deep because its over my utilities trench. but you gotta add it a drop or 2 at a time..its unreal how much difference a couple drops can make... it helps till the plants fill in.
