Swimming pool experts required

I have a swimming pool that is contaminated with algae and various microbes.
Yes the pool water is completely green and hasn’t been maintained.
Any suggestions on what to do, I have 10 kilograms of Chlorine in the form of granules.

I found this helpful with mine…
Answer #2
also do a wiki search on “swimming pool contamination” it states the methods as well as the pumping methods for removing these kinds of organisms growing inside the pool.
Answer #3
i would try shocking it. pool supply stores have a ton of stuff for turning green water into clear water.
Answer #4
Just did that, dumped 5 kilograms of the gunk into the pool.
Hopefully will see results tomorrow.
