Hi bat_billy,I am thinking about starting to use Purigen in my planted aquarium. Will this absorb my aquarium fertilizer?
Purigen will specifically remove excess organic waste before it is converted to ammonia. Purigen will not impact your dosing of nitrogen sources. The only effective way of really removing nitrate is through biological means. Purigen's characteristics allow for it to be discriminate in what it will remove on the basis of size and charge of the molecules.
until you use purigen and as clear and sparkly you thought your water was, it is that much clearer with purigen, beyond what you thought.Just clean dead leaves and do water change more/often. Vacuum (when there are no plants) save your $.
