I have a 50,000 litre pool and I'm finding I am using around 600ml to 800ml each week to keep the PH down.
Just wondering if this seems about right or if Im using too much. The Alkalinity has been sitting around 100-120 ppm all summer, but have let it drop to 80ppm in the last month to see if that helps but I've found its made no difference.
Pool is salt water chlorinated.
I have the opposite problem in that I need PH buffer once every few weeks so can't help you mate. What chlorine are you using? Is it salt pool?
While on the topic of pools, mine is leaving green stains on clothes. I thought it might be copper so I have treated the water several times with a stain remover and the copper levels are not very high now (tested) but it still leaves green stains. I don't over chlorinate so it cant be the chlorine.
Any suggestions?
