Surelife pH Raise - Quickly and easily increases the pH level of water when it is too low. The pH of water may change from the presence or foreign material such as fish waste, heavy aeration, decaying foods, or dead vegetation. The pH may also be low due to the use of soft water. A low pH can cause fish to go into shock causing them to gasp for oxygen. Water which consistently turns yellow over time may be an indication of acidic water.
