Like other live plants and algae in aquariums, red slime is happy when the lights are on and create lots of oxygen through photosynthesis. However, when the lights go off, algae will use oxygen dissolved in the water to survive. If there is not enough oxygen to go around, your fish could be at risk for asphyxiation. If your kH, or alkalinity, isn't high enough, you may have a pH dip during the night as more carbon dioxide is produced and not being used for photosynthesis. Check your oxygen levels and kH levels at their lowest, right before the lights come on or the sun comes up, to make sure your levels are adequate.
