and also does this product remove algae growth? since it also reduces phosphates and nitrates into nitrogen gas..

And also also means technically, we do not need to change water anymore cos ammonia, nitrites and nitrates will be removed in the process. Just need to get the suitable sized filter for my bioload and replaced the Cata pure filter medium when it is due for replacement? That is technically speaking.

The other thing i'd like to check is, your old Hydra 30 can treat 100 ~ 300l, however, the new Hydra 30 state that it can only treat 100 - 200l, does that mean that there's an efficiency drop for both types? If yes, I will change back to the old one instead.
