I would say that if water still has a haze, the conversion is not complete. A CC reading of 1 would also confirm that. Maintain chlorine level, and filter 24/7. I would not add any more additional products until your CC is ZERO.
This is what I found on 'sand helper filter aide'.
....."A molecular cellulose additive that is used to pre-coat sand bed in filter to improve filtration and water clarity."
Some pool owners here add a litte plain DE (a cup or two) to getter better filtration from their sand filters. It may be that your sand helper product is adding to haze. Try NOT using it. However, wait until your CC is ZERO and the haze is gone.
Good luck.
