www.aquaripure.com I uncycled my Aquaripure on my 29g FW tank in order to demonstrate what happens when the Aquaripure cycles. I performed 3 nitrate tests. One in the tank when it had nitrates but the Aquaripure was cycled. I also performed a nitrate test on the effluent of the Aquaripure at that time. I then performed a nitrate test in the tank 3 weeks later when the nitrates had dropped to zero in the tank.
