Hello, the tank is 108 liters, I built it an algae scrubber with refuge lighting, salinity 1.025 nitrate 24 PPM and phosphate 0.09 red sea tests.During the lighting, the air bubbles do not appear until after a few hours of lighting.There are 4 turbo snails. I feed 3 times a day even with frozen, how do I handle the problem?Thanks
