Have you ever wondered what causes algae to grow in your fish tank? According to PetMD, algae grow in environments rich in light, water, and nutrients, making your fish tank the perfect breeding ground.

To be clear, algae isn’t necessarily a bad thing; in fact, many fish like to eat algae. However, too much algae can block your view of your fish, and certain types of algae such as blue-green algae can be harmful to your fish.

While you can take steps to prevent the overgrowth of algae, some algae is likely inevitable in your fish tank.

If you spend hours cleaning your fish tank, this product could be for you. Twinstar is a trusted brand known for creating different types of accessories for fish owners. The Twinstar Nano is a device for freshwater tanks that is meant to inhibit the growth of algae in your aquarium while promoting the growth of other aquarium plants.

How does it work? This product sterilizes your tank water in order to destroy spores from the early stages, preventing them from growing in your tank. With this product, you should not have to spend time manually cleaning your fish tank.
