Hello again : )

I tested my pool with the Walmart kit. My results were:

FC 5+
CC ?
TC 5+
pH 7.6
Tot Alk 170
CYA 50
Calcium Hardness 0

I say 5+ on the chlorine readings because the kit only goes to 5 ppm but the results with the OTO were a very dark yellow and have been there for over 2 days now. It could be at exactly 5 ppm and staying there, or it could be somewhere over 5 ppm and just hasn't dropped under it yet. We even got a good rain yesterday thanks to Alberto and the FC & TC still read as high as the tester goes. This makes me onder how I shock the pool if the tester only goes to 5.

I can finally see the bottom of my pool again. The problem is I can see that the pool bottom is still covered with yellow algae. I've been stirring it up so the filter can get it, then it settles agin, then I repeat. I used a lot of copper algaecide about 5 or 6 days ago. When the water is clear like it is now I go in with the vacuum to get the nasty stuff off of the bottom and I can see yellow water shooting back in the pool from the filter. I'm wondering if the filter just isn't good enough to get it out. The algaecide said it has a clarifier in it that is supposed to make the tiny particles bigger so they will stick in the filter. I don't think that is working very well.

Can someone please tell me what to do from here? Thanks again.
