Ok:
"My pool is green because I forgot to put the winter cover on."
"I'll add 7 gallons of concentrated bleach." He poured it around the edges (looks like a vinyl pool) and threw some further in. Runs pump overnight.
The next day "That didn't do much. I'll use my test strips to see what I need."
"My pH is 6.8, TA is 40 (should be 80) so I think that's the problem." (CYA looked high but he never mentioned it)
"The chlorine kills the algae but to get rid of the green I have to use baking soda." Backwashed the filter ("which is the algae that collected in the filter")
Added 20 lbs of baking soda by dissolving in a bucket and then dumping it around the edges. Runs filter for 12 hours.
"36 hours later, pool still with tint of green." (no mention of additional bleach or baking soda added)
Backwashing every 4 hours and adding fresh water since losing water in backwash. Vacuuming debris and then cleaning skimmer basket and pump basket repeatedly. Backwashing again to get dead algae out of the filter.
"60 hours almost 3 days later, pool looks better, greenness gone but murky (turquoise) with a pile of leaves, which I couldn't see when the water was green."
His conclusion: liquid bleach and baking soda cleared the pool.
"So if you're in a bind and can't find pool shock, liquid chlorine does work."
He then shows a new view of his pool (nothing stated of what he did after the above).
"Pool is clean and clear." (looks clean but not TFP clear in my opinion)
So
@Richard320 it looks like what helped a lot was the adding new water and vacuuming then backwashing. He really does not give a detailed description of everything he does. (like what TFP wants to know) I can't believe a one time addition of chlorine and baking soda is what cleared his pool. It is misleading.
@Donaldson just summarizing the video reveals his method is either incomplete of important details to help any one, misleading or just clueless as to what is actually working.
