3)Since it depends on ammonia being changed to NO3 before the normal cycle can begin, I'm guessing it has to be place in the tank itself and not in sumps or IOS compartments.

Sry for so many noob questions, just like to know a bit more before I commit myself.
Hi,

1. Not all the ammonia are removed. That is the reason why we say that hydra 30 can be used for all tank system , including planted tanks where certain nutrients need to be available for the plants. At any time, there will be transient amount of ammonia in the water , as fishes all still defecating and thus,the BB will still be working.

2. It will remove all the nitrogen-based nutrients when it comes in contact with them, thus , it is fair that to state that it will completely convert the N-nutrients to nitrogen when it comes in contact with them. Like we have describe, there is still transient amount of N-nutrients always in the water. Unless, all the living organisms in the water are removed. All the graphs shows a certain concentration of N-nutrients still available in the water.

3. Hydropure technology will convert all N-nutrients to nitrogen gas when it comes in contact, it does not need ammonia to be converted to any secondary forms.

No worries bro, you are asking valid questions, pls feel free to come back to us, if you need any more info.

Cheers

So... Correct me if I am wrong. All nitrogen compounds that comesbin contact with the catalyst will be converted to N2 and other element? Does it increase affect the pH of the water when doing it's job eg. converting those common amounia, nitrite and nitrate to N2 just like anyother normal cycling process?
