Ok so the frustration starts...I have been reading and tweaking chems and nerding out and have successfully gotten all of my levels perfect. Once my levels all held consistent for multiple months, I added boric acid to get my borates at around 45ppm. All is well, water is crystal clear (although I cannot say that I 'feel' any difference after adding the borates) and maintenance is super easy. However, my daughter's blonde hair is turning a little green. After researching, I found out that my Fusion Soft Nature2 SWG cartridge adds a trace amount of copper to my pool as an algaecide, which also causes green hair. I am not ok with having perfect levels only to still get green hair! It is a very slight green, but I don't want any.
I have looked around and do not see any copper-free cartridges and I cannot figure out how to open this cartridge to remove anything. Anyone have any ideas or experience with this?
