I started to use copper ionizer last season. I totally ignored directions to periodically track copper levels. When I opened pool this year it had algae so I balanced the water and shocked it with liquid chlorine. Water remained green. Well, I shocked it gain. Chemistry was balanced, everything seemed to be good but water though seemed transparent it was still green ... this is when I finally dug deeper and found out my copper .4 ppm (twice the ideal limit). So what happened when I shocked the pool it oxidized the copper making it green. I bought the culator ultra 4.0 as I wasn't sure if smaller pack for take longer to work and might not take all the cooper out. And I tell you you can see water clearing me next day with continuous pump running with culator in the skimmer basket and in two days it was totally clear. So if your pool water is transparent green and you know it's not algae .... test your metals and if they high this product definitely work at getting metals out of the water. I highly recommend it if it is what you need. Review: **Excellent Partner to Orenda SC-1000 for Keeping Pool Water Metal-Free** - I added the CuLator Ultra 4.0 to my pool setup along with Orenda SC-1000 during a fresh pool fill and startup, and the combination worked extremely well. Since I had just invested heavily in a pool refinish, I wanted to do everything possible to prevent metal staining, discoloration, or scaling issues from the beginning. Using these two products together gave me a lot of confidence in the water quality. What I like about the CuLator is that it is incredibly simple to use. I placed it in the skimmer basket and basically let it do its job while the circulation system ran normally. Unlike some products that only suspend metals in the water temporarily, the CuLator is designed to actually remove metals from the system over time, which I think is a huge advantage. My fill water was a concern because metals can quickly ruin a fresh plaster or pebble finish if they are not controlled properly. After startup, the water stayed crystal clear with no staining, discoloration, or strange tinting. Combined with the Orenda SC-1000, the pool water looked polished and stable almost immediately. Another thing I appreciate is that it works in both saltwater and traditional chlorine pools, so it is versatile for different setups. It also requires almost no maintenance once installed. If you are filling a new pool, doing a plaster startup, dealing with well water, or simply trying to avoid costly metal stains, I strongly recommend using this alongside a good chelating product like Orenda SC-1000. For me, the combination has been an excellent preventative approach and well worth the investment to protect the pool finish and equipment long term. ## Features - Removes Stain-Causing Metals — Eliminates Copper, Iron, Manganese & Lead from Pool Water CuLator Ultra 4.0 is engineered to remove up to 4.0 ppm of total dissolved metals from pool water, helping prevent staining and discoloration before it starts.
