Chlorine

I see that a lot of on line pool sites offer a lot of different prices for chlorine. One company offers a 3'' tablet for almost double there normal 3'' tablet, but they claim it has algae and clearifier in it. Is this a scam or is this legit? I thought all chlorine did the same thing

If you maintain a Free Chlorine (FC) level that is at least 7.5% of the Cyanuric Acid (CYA) level, then chlorine alone will prevent algae growth and there will be no need for algaecides, phosphate removers, clarifiers, flocculants, enzymes, etc. Just keep in mind that for every 10 ppm Free Chlorine (FC) added by Trichlor, it also increases Cyanuric Acid (CYA) by 6 ppm.
