Help me get my pool back! Green with algae or ?

[Josh_U]

I've maintained my cl at 25-30 and added a full dose of the no mor problems algaecide suggested by Ben. Still not seeing any difference in water quality and wondering what my next step should be. Filter cartridges are 10+ years old and this is the worst our pool has ever been. Should I replace them or play with partially draining to lower my cya next? We've been fighting this for more than 2 months now.

Arg-gh! I may have missed something.

=> Do you have a heater, or have you been using chlorine that has copper in it?
=> Is your water clear, but green?
=> If you pour bleach on the steps -- slowly -- so it contacts the green dust, does it bleach it out?
=> When you clean your filters, what color is the 'goo'?
=> How have you been adding chlorine to your pool?

Pool is just about all cleared up now. Chlorine, a little algaecide and a lot patience is all it took! Just one more question though. When/ how do I know it's ok to get in the pool and when can I let the cl come down from shock level? Thanks!

As long as there is some stabilizer in the water, high chlorine doesn't hurt people -- might make your eyes sting a bit, but that's about all. But, you should were old / no swim suits!
