After 5 years of endless fighting with algae during the summer, I finally decided to convert baquacil into chlorine. I just started conversion yesterday. After applying bleach and letting the pump recirculate for overnight, I can see that the water turns green now.
now I have a question: I am using a sand filter. I read from somewhere that during the conversion process if I don't use filter but just recirculate through the filter, I might not need to change the sand at the end of the conversion. And this is why I am only using 'recirculate'. I am wondering if using the filter would help the conversion. Any comments?
