Thx again Wyld... I had to do a lot of maint. on my new Armatus tank so I didn't get a chance to get the pics yet. I will remove the Chemi Pure tomorrow. Since the stuff lasts like 6 months I can put it in the new Armaus tank since I will not have any live plants in with them. ( I don't want to throw away $50.00) lol.... How long does it normally take for them to go through that stage??
