We're in our 3rd year of a BAQUACIL pool. It's a 32x16 (20,000 gallons) above ground pool planted into the ground (I've enclosed a picture). Our pool sits outside in New Mexico's strong sun all day long. The first year was fantastic, until late in the season when I broke out in a nasty rash from the baquacil chemical CDX. We tried to go forward without CDX, but if you can't use CDX it pretty much doesn't work. We've struggled w/ pink slime and cloudy hazy water. Now it's taking 4x the required oxidizer to come close to a normal reading, and it only lasts for a day or two. We've decided to switch over to chlorine, and have read your post called "Convert Your Bacqua Pool to Chlorine." Our first questions are how long should we expect this process to take and since we have such bright constant sun should we plan to shade the pool? Any other suggestions would be greatly appreciated.
