Please consider changing to some appropriately sized pellets/wafers like Hikari products which say they do not cloud the water.
Try getting some stem plants like Hornwort in m experience not great in low pH water or Anacharis/Elodia sometimes referred to as water weed, or other fast growing plant, it can lay loosely on top of the tank and float. Rinse in treated water at least over night after bringing home, make the water conditioner extra quantity to treat it, and rinse the plants well before putting in and soaking.
With mine, just one day the water was mostly clear, and the next day it looked like nothing ever happened!
