Hi MPurcell, thank you for your feedback on the matter. My water is actually clear unless I have my air and pump on then it gets cloudy but it's only from oxygen from what I can tell. Once the air and pump are off, I'm back to crystal clear water. I am such an amateur I have no idea what you mean by bank, I have heard others use this term as well. I typically use the strips and try to keep my bromine etc within the colors as close as possible.
I bought the tub used 2 years old, when I got it it was sitting in dirty water, they are possibly suggesting I put in a cleaner run it 2 hours drain and refill. They are thinking possibly a pipe fungus or growth. p.s. this is the company here, https://dazzlewatercare.com/
I use ta = to increase ph, than little ph to bring up to perfect level, bromine granules to start the bromine high enough and a floater to try and keep it at a proper ppm.
I have added pictures on my chemical products into the shared google drive.
I will also try to get a hold of a better test kit I agree these strips are very hard to tel where you are.. the first picture is all my chemicals, the seccond is what I do in the specific order to get to my desired levels for ta, ph, bromine and hardness
