This is a commercial pool and we use trichlor. 40k gallons.
The pool doesn't get any sunlight during winter. How crucial is UV to trichlor? Pool turns green many times during the cold season even when tje free chlorine is usually at around 5-7 ppm with CYA at 30-40, pH at around 7.6-7.8 and TA at around 110. Pump runs 24/7 and is a heated pool. Around 120 GPM flow rate.
In order to combat this, I added 10 oz of phosphate remover every week and that helped a lot.
I'm thinking of using liquid chlorine this winter to try and see if it works better.
We're also thinking of switching over to cal hypo feeders as we have ORP controllers tied to our trichlor feeders and it doesn't work too well due to CYA.
