+mcallahan Posted July 7, 2011 Share Posted July 7, 2011 Polyp Lab's liquid carbon dosing agent. I ran my tank on this for 2 years and got my tank down to 0 PPB phosphates, 0 nitrates. 190mL left/6.4 oz left. My 100G tank took 2mL a day at a full dose, this is 3 months supply worth if you have a 100G tank (recommended dose is .25mL/25 gallons) $20 Link to comment Share on other sites More sharing options...
