I have had a 23l Edge set up for about 2-3 months now, I have 6 crs (was told 4 are SS and 2 are SSS) and 4 Horned Nerite Snails, they are all doing very well apart from the tank itself. I have Seiryu stones, 'cuba' and hairgrass the only issue is hair algae, normal algae and brown algae, it just will not go away.
I dont want to use treatments because of the shrimps and snails, any ideas?
