I know that much has been written on this subject and I've read the instructions on this site as well. I have an 18x4 pool currently using Bacqua. Water is blueish green and cloudy. Been fighting the pink slime for two years. I decided this year " no more". I have a 1hp pump and an old Hayward filter model # 142-K. The filter is so old that all information that may have been on it is no more. I was lucky to find the model number. If you have any info on this model I would appreciate it. Not sure about flow rate, etc. I live in coastal southeast North Carolina so it gets pretty hot in the summer with lots of sun. I have a swg on order and want to change over while I wait for it. I read on another forum that instead of adding the chlorine that you could add two pounds/ 10,000 gal. of dichlor and that the bacqua goo would form on the surface and sink to the bottom overnight to be vacuumed to waste. Repeat if Bacqua still present. This seems a lot easier than dumping all that bleach in the pool and faster. Any idea if this would work? What would the dangers be in doing this instead? I figure after the Bacqua is gone it will be easier to stabilize and get the numbers in order. I have no test kit, only Bacqua test strips. The reading are, Low Bacqua oxidizer, 50 Bacqua sanitizer and algistat, ph 6.8, and total alkalinity around 90-100 ppm. Hope this is enough info. If you need something else I'll try to get it . Thank you.
