Hi, I've started my conversion from baqua to cholrine and just ordered my TF100 testing kit, I have been at it since monday night after wasting money on shock. Started adding bleach 8-10 gallons aday and my OTO is reading a RED color so I know im above 10ppm. I still have mint green color water and feel as if im getting no where fast. Im brushing and backwashing my filter 1-2 times daily due to the lack of circulation in the pool. Do I need to get a new filter now and replace again after conversion?
