Welcome to our forum.
PH and alkalinity can go hand in hand but don't have to.Low PH has more killing power than high PH. This might be the reason but 4 teaspoons is a lot of chlorine and should last a long time. My tub at 400 gallons, chlorine would be at 6 PPM and 24 hours later I certainly will have a residue. I put in 3 teaspoons of dichlor 2 nights ago after soaking and I had slight pink (I estimate about 0.1 PPM) this morning.Stabilizer is in dichlor and trichlor. It is used mostly for pools for UV protection of the chlorine. In a tub it serves no purpose but after a few months depending on how much dichlor is used will build up.
Correct me if I'm wrong but won't a 4ppm chlorine level skew all other readings?
I had the same problem last week.Use Soda ash to bring alk down then bring ph and alk back up together w/ baking soda or spa up.Btw, you might want to consider getting a taylor k-2005 kit. It will give you some more accurate readings. It has done wonders for me.

High levels will bleach test results. 4ppm is not that high. Thats what we shower in and drink out of the tap.
