<p>API pH Up 118ml<br /><br />pH Up is a liquid pH raising product for freshwater aquariums. By neutralizing acidic substances in the aquarium, pH Up effectively makes the water more alkaline.<br /><br />The pH may rebound down to the original pH depending on the level acid in the aquarium. Several consecutive treatments with pH Up may be necessary to adjust pH to the desired level, but if there are fish present in the aquarium, the pH should not be changed more than .2 in a 24 hour period.<br /><br />Aquarium Pharmaceuticals pH Up contains no phosphates and may be used with live plants<br />DIRECTIONS:<br />Determine the pH of aquarium water with an API pH Test Kit.<br />To raise pH, add &frac12; teaspoon (2.5 ml) for each 25 U.S. gallons of aquarium water.<br />For larger aquariums, add 1 teaspoon (5 ml) for each 50 U.S. gallons of aquarium water.<br />Take another pH reading before adding another dose of pH Up.<br /><br />Some fish may be sensitive to pH adjustments greater than 0.2 in a 24 hour period, so changes of this magnitude should be done with extreme care.<br /><br /><br /></p>
