Whether your chlorine is "good", "too much" or "too little" depends on your stabilizer level, which you haven't reported yet. If you can get us that, using the disappearing dot test rather than strips, then we can better help you.

The best algaecide you can get is chlorine--and lots of it. Whether you just have dirt/pollen or actual algae growing is sometimes hard to tell, unless you can measure how much chlorine you're losing overnight when the sun isn't out.You can't measure that accurately with an OTO kit, which is why we recommend the K-2006 kit that can be found in the link in my sig.

HOwever, at the very least, we're going to need to know your CYA level to help you with your questions...
