How do they protect fish?
By breaking down nitrates. Nitrates are dangerous in high concentrations. High enough levels can even start affecting your fish. Too much nitrate means too little oxygen, so it’s a good idea to check on your fish periodically.
If the fish are staying near the surface and they look like they’re gasping, the nitrate levels may be too high. You can find a nitrate level testing kit online. Aquatic plants can deal with some of the nitrates, but they can’t handle it alone.
