So I just had a new liner put in today and currently filling it up with the hose. I assume the cya will be zero. I know that I should have around 35-45 ppm to protect my FC. I have some trichlor tablets, and 3 one lb bags of dichlor shock. Could I just use my tablets and shock to bring my cya level up, then change over to Clorox,or just buy some stabilizer? Thanks in advance for replies.
