(2-Pack) Zinc Anode Weight - Anti-Electrolysis Sacrificial Anode - Galvanic Anode for Passive Cathodic Protection - Bolts Inside or Outside Skimmer Baskets - Salt System Swimming Pool Must-Have

  • ...isk, but it’s probably the most effective weight for your skimmer baskets. It’s cheap, effective, and will save you from headaches later on.
  • ANTI-ELECTROLYSIS SACRIFICIAL ANODE - Aside from weighing down your skimmer basket, this zinc anode weight neutralizes the salt in pools with salt systems, protecting metal components of the ladders, screws, rails, lighting frames, and other metal components that are in constant contact with the saltwater.
  • GALVANIC ANODE FOR PASSIVE CATHODIC PROTECTION - The way the sacrificial anode works is that it corrodes first before other metal components in the pool - the zinc (anode) basically protecting more “noble” metals (cathode). Together with equipotential and pool water bonding, this galvanic anode will aid in preventing corrosion.
  • INCLUDE 2 CABLE TIES - Whether you bolt it inside or outside your skimmer, the sacrificial anode will work its magic. It will secure the skimmer basket in place. There are 4 mounting holes, the center hole is 5/16 inch in diameter and the 3 outer holes are 1/4 inch in diameter.
  • SALT SYSTEM SWIMMING POOL MUST- HAVE - Prolong the lifespan of your salt system pool’s metal components. This is imperative even if you haven’t yet noticed signs of corrosion. Don’t wait for corrosion t....
