Why is the dissolved oxygen (DO) so low in my tank? Is that bad?

Ideally, you’d like to have about ppm oxygen in your tank for healthy fish and plants. If your dissolved oxygen is less than that, it may be due to the high temperature of your water (as temperature and dissolved oxygen have an inverse relationship) or an algal bloom. One way to increase your dissolved oxygen is by adding aeration pumps.
