Long story short, if you are looking to find copper-free zinc sacrificial anodes you want “Pool Tool Anti Electrolysis” and, as of today, you want to get them from GetPoolParts.com.
To protect my Endless Pool Fastlane I use Zinc Sacrificial Anodes.
The purest source for these I had for these was from Endless Pools themselves. These used to cost a little over $15 each from them which was pretty pricey for something I would need to replace 2-4 times a year.
Similar anodes are used for maritime part protection (inboard motors, hulls, etc.) for a fraction of this cost. However, the maritime anodes that I have found are typically not so pure as I hoped. There is enough copper in them to cause blackening of stainless steel which quickly becomes unattractive.
This…
becomes this…
So I bought a healthy supply of the anodes that lasted me until this year.
When I went looking I saw that the price has now increased to about $24 for these, which is patently absurd.
What I want specifically is a product called “Pool Tool Anti Electrolysis”.
So I came across a site called “Get Pool Parts” that had them available for less then half of where I was seeing them anywhere else ($12.16 per anode). Ordinarily this would be a red flag as deals that are too good to be true are there to suck you in on the internet.
Their BBB record was just OK (B+ as of this writing) but I couldn’t find anything really bad about them in searching for scams or problems. Another vote of confidence for them was a few postings on Troublefreepool.com which has been a great source of pool information for me in the past.
I ordered these really late Tuesday night (2 am) and they arrived on Saturday morning. Everything was exactly as specified. I couldn’t be more pleased. I just wanted to give them a shout out and also let people know about this option and my good experience should you wish to avoid the extortionist pricing for this basic part.
