I did the test in my kit for cyaWith your CYA (did you do the dilute test as it may be higher than 100) I would really not use any more trichlor or dichlor. They will not add enough FC fast enough to keep the pool sanitary. Use at least 5 ppm FC worth of liquid chlorine each day.
Use aeration to raise your pH. It is low because you have been using trichlor and dichlor.
I would not personally get in this pool until the CYA is lowered and the FC is kept in range to keep it sanitary.
If you can point a return up so it breaks the water surface that will help. Swimming also aerates, but I would be concerned with that with your current chemistry.Also
how the heck do I use aeration to raise my ph?! My pump isn’t enough?!
