Hi everyone. I have been browsing this site for months and have found a lot of great tips which have helped me so far. I purchased a home on Long Island (NY) and closed Nov 20, 2015. the previous owner closed the pool and everything seems to have been done properly, so now i'm taking over. So far, my only experience with the pool is maintaining the water level in winter and lowering it with a sump pump. The water was quite clear up until a month ago when we had a heat wave during very early spring, so i got a lovely bloom of algae. I set up the pumps, undid all the winterization plugs, connected all lines and had the system up and running pretty quicky.
Where i'm at:
I ordered the TF-100 Kit with all the extras except for the mixer, and it should arrive in the next 2-3 days.
I opened the pool Saturday afternoon. The pool looked like this:
Brought a sample to Leslies to test on Sunday, and got the following readings:
Even though i dont have the testing kit yet, i wanted to get a bit of a head start since this is what the pool looked like after i opened it. Sun 05/15/2016
I added 3 gal of Star Shock which is 12.5% sodium hypochlorite, did some brushing and have been running the pump since then. The next morning 05/15/2016, the pool looked like this. much clearer but still cloudy in the deep end. I brought in a sample of water to leslies again for testing and got all the exact same numebers. IE FC which should have been around 12 (given a 30cya and the 384oz of 12.5% sodium hypochlorite i added based on the pool math section of the site) fell back down to 1. What is more odd to me is that the CYA reading after is now 0 from 30 before "shocking." i know a low CYA (30 or so) is better for shocking, but isn't 0 bad/indicative of a problem as well? Other factors may be that i added about 1.5-2" of water (pool is 20x40) after adding the shock since the level was still to low for me to vacuum, it currently sits 2/3 up the skimmer.
I'm not sure how i should proceed. I dont want to waste chemicals but i also want to get a bit of a head start since my kit wont arrive for another several days. I figured i couldn't go wrong just getting the chlorine levels up to shock levels for a few days, but now that my CYA is lower i'm concerned. Should i just wait for my test kit and get the rest of my numbers in line or can i proceed with shocking the pool the way i have been? Also, should i wait to add salt until i SLAM?
Just to recap: Current levels 24h after adding 3gal of 12.5% sodium hypochlorite and nothing else, pool clarified a lot FC returned to same level and CYA fell to 0 (not sure if that is a false reading).
Thanks, I appreciate any help!
