2 year old plaster with algae adhering to pool floor

[rocks911]

So, I have an 18,000 - ish gallon pool that was plastered a couple years ago. I have a salt system that seems as though its working. Unfortunately I have a "fruitless" pear tree hanging over my pool dropping a bumper crop of tiny sugary pears that sit on my pool bottom apparently feeding whatever is growing on the floor. My Polaris crapped out when I needed it most, but hey it was 2 years old, so... but thats another story.
Im not too sure about my chlorine generator, but it sure looks like its generating away (I have a see- through plastic pipe where the elctrodes sit) and I think that because of the fruit falling into the pool and contaminating it the chlroine is being quickly dissipated.
So I got some liquid chlorine and a bottle of Pooltec Algaecide and chlorine boost but it hasnt made a dent in whatever is growing.
I have been brushing regularly and have run the pump 24 hours to circulate everything but still not much of a difference.
All other parameters are normal...ph acceptable range, chlorine level good, etc. etc.

Any suggestions?

I hope it comes across in the pic. I should have resized. But its a yellow-brown funk that just refuses to be brushed away. I super-chlorinated the pool and added 40 oz of Pooltec Algecide and ran the pool 24 hours. The pic is after. Its not budging.

What test kit do you use?

Post your water chemistry in the form…

FC
CC
pH
TA
CH
CYA
SALT
WATER TEMPERATURE

Are you familiar with our SLAM Process to get rid of algae?

Algaecide may prevent algae for a while but once it is in your water it is worthless.

Thanks for the reply,
Honestly I just went to the SLAM page and it seems to be working... duh. I remember being here years ago, it takes days of brushing and vigilance but I think Ive got it going my way.
Fingers crossed.
