Skims dissolved proteins to curb nutrient and film build up. This will improve water quality, oxygen exchange, and light penetration. Includes a 5W, 450Litres pump. Works with freshwater and saltwater aquariums. No additional part needed.
I have this hanging in a 80 litre all in one nano tank and it works fantastically no micro bubbles at all only thing that you have to do is clean the sponge once a week I added this in to my weekly water change routine 6 months and going strong
