No new information, just to update that pool is looking a bit better, may be halfway through. Already backwashed the filter couple of times (pressure increased overnight to +6) and the skimmer (fine sieve) is catching lot of live algae(green). But loosing 5+ppm of Cl overnight. I guess it might be a better to add a bit more conditioner since I have below 30ppm CYA and the sun is brutal in Phoenix. And need to order more Taylor DPD-Titrant reagent as well before it gets finished. Thats all.
I am really interested to know how people remove algae without a wire brush. Big difference for me.
