USAGE NOTES: **DO NOT MIX: PC PURE includes an Anti-Microbial agent. Mixing of any other anti-algae or anti-microbial agents with PC PURE fluid is NOT recommended (this includes Liquid Utopia). Adding additional agents will cause a chemical reaction with the agent currently in the fluid. This will cause the fluid to perform at less than optimal levels and may cause unwanted build up.
