Nice info mam, I'm your channel follower, and forwarded your channel link to my friends and relatives. Your explanation and demo always informative and nice. Only suggestion about this video is pronunciation is Beyond blue (ಬಿಯಾಂಡ್) and you pronounced behond (ಬಿಹಾಂಡ್) which sounds different. Its just my small suggestion madam. And you had to inform that this Beyond blue is not a chemical and also it will not kill bio creatures inside the sanitary PIT and hence sanitary PIT will never load fully. So its cost effective too.
