Hello all

So glad I found this site, there is a great wealth of knowledge on here that I have been trying to digest over the last two weeks.

Here's the scoop on my pool: bought a house last August with an above ground vinyl lined pool (33x18) approximately 18,000 gallons. Pool was not opened all summer but I through some winterizing chemicals (not sure what they were bought from pool store) in the fall. Took cover off 2 weeks ago and water was surprising clear with a bunch of leaves on the bottom. First mistake, I took cover off too soon. Didn't fill up pool until a week later and pool turned green since there were no chemicals and filter wasn't running.

A week later pool was filled (maybe 4-6000 gallons) and I got pump and filter running (hayward De) I also dumped 4 gallons of liquid shock (buckmans 12.5% sodium hypochlorite) and 1 bottle of algaecide. Pool turned from green to cloudy white basically within a few hours and was much better over night. Continued to run de filter for next 4 days backwashing and regenerating fairly frequently (algae).

Here's where I stand now: tested with Taylor 2006

Fc 0
CC .5 (maybe .5 maybe 0?)
Ph 7.6
Alkalinity 90
Cya 0

I poured about 128 ounces of bleach in tonight and have had 3 tablets (8 oz each) of trichlor in a floater for the last 2 days. Will test again tomorrow.

My thoughts are, get cya up slowly while also raising chlorine levels. I believe trichlor will raise my cya (and chlorine) but is there a quicker way? Am I on the right track? Should I be doing anything differently? I've also been vacuuming throughout this whole process, it seems the algae may have died and sank to bottom since it seems I have to vaccum almost everyday for last 3 days. Pool is generally clear little cloudy though could be better.


Also I have been having to regenerate my de filter a lot almost every hour when filter is running. I assume this will get better as algae goes down(doesn't seem to be too much left floating) but I also believe the de fingers could use a bath in muriatic acid to clean them, I don't know the last time they were cleaned and I only hosed them off before running this year.

Thanks!
