does it really reduce nitrate?

also how is it compared to K1 media?
im thinking of using both K1 and marine pure.

Dont use it personally but a lot of friends give great feedback on it.

Quite keen on responses comparing it K1, I believe K1 would be better being moving resulting in old / dead bacteria being remove but this is just a theory.
