My chlorine has been high for three days now between shock and bleach, lots of it too.
I can see the black spots getting lighter and they are not as slippery when i step on them.
I've been brushing every day and my neighbor was nice enough to donate a bottle of
HTH Super Algea Guard to the fight, which i just put some in today. I cant tell how high the chlorine is but when I test the water it is orange instead of yellow so I guess it's pretty high but here are the numbers ph 7.8 ta 120 cya 40 tc high calcium 310


Well i think i got my problem on the ropes, but my ph is getting a little high like 7.8 or 7.9 should i lower the ph to 7.2 or 7.3 or leave it high until the black algea is gone. Also should I use some black algea killer or just stick with the bleach and free bottle of hth super algea guard.
