Soft Scrub In-Tank Toilet Cleaner Duo-Cubes, Alpine Fresh, 2 Count

i bough this less than 1 month ago. i put in toilet and it wasn't turning blue, eventually after approx. 1 doz flushes, there was very very pale blue water in toilet bowl. yet on my 2nd toilet in the home the cube activated after the first flush. not impressed with this product, too inconsistent .

I bought two packages of the Duo scrub since I have hard water and see some aspects of rust in my newly built home. After using only 2 each per bathroom over the course of 2 months, I started to notice a dark colored strips of film and black flecks in my toilet when flushing. Upon further investigation I found both tanks covered in a thin gel like film throughout both tanks. If you disturbed the film in any matter it pulled away from the tank walls and ended up in your toilet. After seeing this, I took a toilet brush throughout the whole tank and then added about a cup of bleach to each tank and let set for almost 1 hr to get everything to dissolve. If I have to look at the lesser of two evils, I prefer to have to clean my toilet bowl more frequently rather than add a gelatin slime to my septic system as that would most likely cause me significant issues downstream. Very disappointed to see something like this from Soft Scrub.
