The best way to inhibit the effect of galvanic corrosion is to use a zinc anode
Zinc is a metal that gives up its metal ions faster than other metals in the pool
Pool Tool 2" In-Line Anti Electrolysis Zinc Anode | 104-C2
The inline zinc anode is attached to the bonding wire thereby protecting all metal parts against the effects of galvanic corrosion. Available in 1-1/2” and 2”. The see through housing allows the anode to be easily replaced when depleted. No replumbing required. A must for salt water pools
