For best results, use 1 kg of ROWAphos for every 1000 liters of aquarium water. Gradually increase the amount of ROWAphos in your system to avoid shocking your aquarium inhabitants. Phosphate levels should be tested regularly to ensure proper removal. Do not reuse… |

A: Either one will clump if not used properly but Rowaphos is a great product!

**Q: Does this need to rinsed?  I saw some people rinse it and others don't..what are your suggestions?  i will use it within a reactor on 120 Reef.**
