Wow, so when I thought I was 50% over, I was more than 130% stronger than Excel. I haven't seen any harmful effects, though. Thanks for the info- that's a lot of reading to do.

ErioLover- Cidex works great without the activator. Like you said, the algae that I still have was resistant to Excel also. And we are saving a LOT of money. I didn't use the activator because I thought that anything that is added to make a test work would be too strong, like I would never put the chemicals in my water test kits in the tank. I honestly have no idea if that is logical, but I didn't want to add what I couldn't identify.
