Dymax Bact Up 500ml

This has a high pH Nitrosation beneficial bacteria formulated specifically to establish biofiltration for alkaline cichlid water. It enhances the rate of nitrification, where ammonia is converted to nitrites (NO2-) and then nitrates (NO3-); denitrification in which nitrates are being removed; and organic waste degradation, in the aquaria through complete nutrient remineralisation.

This can be used weekly after every water change. This will not harm your cichlids for double dosage.
