Aerator diffusers (2) spread 1/3 apart are on 1 ft. high pvc frame stands off of bottom at depths about 8 ft.
The concern about aerating more often (especially during direct sunlight hours) is around mixing the water and slight amount of suspended algae (greenish tint) that may reflect the sunlight and absorb the sun more, like a convection oven effect. Should I be worried about this? The water clarity is aobut 3 ft. moderately viewable and not greater than 6 ft. at all viewable.
