Hi,

kimco, hahaha.. I never thought that way..one good point...

Yes, I agree with you, RuslanJamil. The only thing is as I said before the aquarium must be in top conditions, enough remaining plants to do that, IMHO. As removing plants, less uptake of ammonia (ammonium). As a matter of fact, aquatic plants remove ammonia from water quite quickly, within hours. They also prefer ammonia (ammonium) over nitrates and also prefer leaf uptake of ammonium as opposed to root uptake, actually.
