I will be going to alasaka for a cruise, and wont have anyone to add bleach while im gone. Now I still have a big bucket of pucks, and my floater. Would adding like 3 pucks floating around for the week in the floater raise my cya tremendously? Any suggs on how many I should use? My current cya is at 50, and that's where I want it to stay, since I live in dallas....Thanks
