I'm very new pool owner, and I just opened up my pool about 3 weeks ago. It had lots of green alge from the winter, so I dumped about 6 jugs of chlorine in it, ran the filter 24/7 cleaning it each day (cartridge), and vacc'd it each day. It got nice and clear.
So today I decided to do my 1st test of the new season (I'm very inexperienced with FASDPD) and I do my ChlorFree CombChlor test. I added 3 scoops of R870 to a 10ml sample. No color.
I then tested the CYA to see if it's really high and eating my chlorine. I used R-0013 and 7ml of pool water to fill to the 14ml mark and it's totally clear. No color.
PH measured a little above 8.0.
I'm confused. There is some algae forming in my pool now, so I'd like to add clorine tonight.
I have baking soda and borax at home along with 3 jugs of liquid clor.
It's a 6000gal bean shaped fiberglass pool with a cartridge filter.
Any advice is appreciated!!!!
