the water its not crystal clear, but I think is normal during this stage , yes I have 3 turbo snail plus other 3 snails smaller than the turbo snail, but I don't remember their namesThe tank looks clean , and is just going through its stages of getting mature .
A sea hare is an algae eating machine, and will need nori or some kind of extra food in that tank !!
Get lots of snails they will keep it under control.
