Tetra 77140 EasyBalance PLUS Water Conditioner, 16.9-Ounce

EasyBalance with Nitraban offers a number of benefits, including reduction of phosphate; stabilization of pH and KH; and replenishment of essential trace elements and minerals.  Nitraban adds nitrate reducing granules to the water.  The while biodegradable granules settle into the gravel where they are broken down by bacteria.  The bacteria consume nitrate, which reduces food for unsightly algae in the aquarium.Available in 16.90oz, 500ml container
