I think I may have killed the algae and can begin the removal process. Here is my next problem. I do not have the cya reagant and it doesnt look like i will have until next week. We are going out of town this weekend and would like to shock it so that it will be at a safe level for us to leave for the weekend. Can I go ahead and add some stabilizer. I am assuming I dont have any due to the fact that I can now maintain a level overnight but not after a day of full sun. Is this correct assumption? Any suggestions??
