Description

Keep your pool water clean and clear all season long with the Set of 2 Main Access Power Ionizer Replacement Chamber for the Power Air Ionizer Hybrid Pool Water Treatment System. Designed for annual replacement, the ionizer dramatically improves the clarity and quality of your water by removing harmful materials in the water without the use of dangerous chemicals. The process is pH neutral and offers natural minerals that are safe for you, your family, and the environment. Chambers for an ionizing system usually need to be replaced every 1-3 seasons.

The ionizer reduces the amount of time you spend maintaining your pool, letting you protect your pool and enjoy the water year after year. Keep your pool water crystal clear season after season with this 2-Pack of Power Ionizer Replacement Chambers from Main Access.

  • This is the one to buy
Size: 1 Pack
Dont buy the cheaper versions of these they are B rated stock and leak. This is the original quality from the pool manufacturers and its a great part. Took about 3-5 days to get my copper back to the right level to kill algae.

  • Ionizer replacement chamber
Size: 1 Pack
After 2 weeks of trying to get my pool cleaned, I finally broke down and I took my water to be tested at Leslie Pools, the guy told me that my pool needed conditioner, tons of shock, yellow out and blue brite in order to get cleaned. He didn’t have a clue of what I was talking about when I told him that I have an ionizer ( he said that it must be some kind of gimmick) I bought into it and purchase almost $200 worth of chemicals, unfortunately, that didn’t work. Wasted money. Then I decided to order my replacement through amazon and I was pleasantly surprised that I wasn’t going to have to pay an arm and a leg for it. I ordered it and received it the next day. Installation was very easy, but I had hoped that I didn’t have to drain the water first. Anyhow, it took 2 days to get the pool looking blue again. I certainly wish that I had purchased this replacement before spending money on harsh chemicals. I will be purchasing it again when needed. ... show more

  • Make sure your Total Dissolved Solids (TDS) is between 1000 and 2000 ppm
Size: 1 Pack
These are great; I'm on my third which is a lot cheaper than chlorine. I had a Hayward sand filter tank that had a leak so I've added lots of tap water. The TDS of my city tap water is unusually low, about 100. I checked my pool TDS and it was less than 500 ppm. The ionizer needs 1000-2000 ppm to work, otherwise nothing to ionize. I've added 40 pounds of salt to bring up my TDS. Mine is a small above ground pool and 1 pound of salt adds 12 ppm to 10,000 gallons. If the ionizer doesn't work in your pool (won't make copper), check your TDS. ... show more
