Still green (ish)

Is your water clear? If so, it really does sound like metals from the Nature 2. Take your ph down to 7.2 add a metal out product which sequesters the metal. Such as sequasol, metal free, jacks magic or any other that says it sequesters metals. You can find it at a pool store, or anywhere that sells pool chemicals. Use at least as much as it says on the bottle for the amount of water that is in the pool. Let us know if the water changes color.

Is there any CC (combined chlorine) in the pool?

The last time I had my pool tested for metals was about a week ago and there was none indicated. I have been using the N2 sytem all season (finally took it out last Saturday). The water is definetely not clear and there in no CC in the water.

Thanks Again

If it's not metals - then you are not getting the chlorine up to a level where it will kill the algae. You need to get it to 20ppm - test 3X a day and every time raise it to 20ppm - the more you are able to keep the chlorine level high and steady - the shorter amount of time it will take to kill the algae.

I would still recommend that you have your water tested again for copper. When you shock your pool it will cause the metals to come out and stain your pool - which would not be good.

We just had the metals tested and they're fine. I have been consistent with keeping at shock level (since converting to BBB last week), but I'm getting discouraged because i'm not seeing any improvement.

Then take it to 25ppm and keep it there. When you are testing through-out the day - where are your chlorine levels?

Today my FC is 20 and has been consistently at least that high for the last week. I even had it up to the 25+ level for a few days.
