My turbo snail is driving me crazy! He keeps blocking the weirs in the middle of the night to my AIO tank. The water level in the back drops because it is being pushed out faster than it is coming in since he is blocking it. So then my ATO dumps a whole bunch of water in my tank that I don’t need. Messes up salinity and fills the tank higher than I want. Anyone have recommendations on something I can put over the weirs so that he doesn’t block as much flow?
