I am new to the forum. We have a 30,000 gallon in-ground pool and have been using Baquacil for approx. 10 years. (We have well water, if that makes a difference.) As I've read in other posts, the Baquacil worked great for quite a few years. We had no problems maintaining it for the first 7 years or so, but for the past 3 or 4 years, we have struggled to keep it right. Main problem is with what I think is mustard algae; had sand changed last year, and can usually clear up any other problems like cloudy water, etc. After a lot of thought, talking with others and reading posts in this forum, we've decided to covert to chlorine and purchase a SWG.
I have read and printed the 'Convert Your Baqua Pool to Chlorine' information in the Pool School section and ordered one of the recommended test kits, which came in today. I called the company where we get our pool supplies and told them that we would like to convert; they were also the ones who installed the pool. She sent a one page instruction sheet that has several steps after the pH adjustment but prior to adding the Chlorine. The sheet that they sent says:
1. Adjust the pH to 6.8 - 7.0 (in highly buffered pools, try to get pH as close to 7 as possible, avoiding excessive acid addition).
2. Add four pounds of Pool Breeze Non-Chlorine Shock per 10,000 gallon of pool water.
3. Add a chlorine compatible chelating agent.
4. Filter continuously for 48 hours.
5. After 48 hours, readjust pH to 7.2 - 7.8.
Then it starts directions for 'shock-chlorinating' the pool daily, preferably in the evening.
My question is whether it's necessary to do these steps after the pH adjustment prior to starting what the Pool School recommends? If they are not necessary, I don't want to do them, and your directions seem very clear and achieve what appears to be great results. Any comments or suggestions will be much appreciated. Thank you.
