Learning a lot from TFP!. Just bought a house with an 8,000 gallon above ground vinyl pool. Was pretty green when I took off the cover, but not too bad compared to what some people have to deal with on here.
So I just got the filter up and running (DE filter), and trying to SLAM the pool. I dont have one of those FAS-DPD testers, just a set of test strips.
Initial test shows:
I know I am a bit low on CYA. I did add a couple lbs of stabilizer to a sock and threw it in a couple days ago when CYA was at 0. Almost all of it has dissolved into the pool, but the CYA still seems low.
To start the SLAM process, I added the amount of bleach that PoolMath told me to in order to bring FC up to shock level. tested after 5-10 minutes, and there was no change on FC.
After about 30 minutes, added another 121 oz, and waited 10-15 minutes. Testing again is STILL showing FC around 1. It hasn't budged.
Am I doing something wrong? or is this normal, and do I need to keep dumping beach in until the FC is at Shock Level. I wanted to ask here so I dont damage the pool.
