my pool is green! i had this last year i litrerly put 15 pounds at a shot 2 times a day and i would test 20 min later and there was no fc!!!help? what could it be? Last year i ended up putting in non chlorine shock in a few times and eventually i got it out of the lock, any ideas?
just opened my pool and no matter how much shock i put in when i test the water the fc is at close to 0

Are you able to hold CYA ? If that gets eaten quickly as well, it's likely to be ammonia.

The cure is a rapid dosing (of alot of chlorine), which sounds like you inadvertently did last year.

Are you testing your own water? What test kit are you using? You first need to know your CYA level and then refer to the CYA/Chlorine ratio chart for the target level of chlorine needed to SLAM (shock level and maintain) the pool water.
Please check out SLAM - Shock Level and Maintain for all the information you need to get your water back to blue!

Here are a couple of steps directly fro the article posted above
Confirm that You Have an Ammonia Problem in Your Pool Water
- Your CYA will be 0
- Add chlorine for 10 ppm and test your free chlorine after 30-minutes. You likely have ammonia in your water if you lost 80%+ of FC in 30 minutes
- Your CC tests > 0.5
- Optional: An ammonia test indicates the presence of ammonia
The link in post #2 explains it all.
Afterwards you'll need to SLAM which JodieM linked in post #4.
Good luck and keep us posted.
How are you testing ? Test strips and the pool store are notoriously wrong for CYA. They will send you down the wrong path.
Guilty as charged! I ordered a proper kit i am waiting to get it i figured if the strip and store say the same i could rely on it
But regardless I gather whether it's ammonia or not I should just continue shocking and checking levels every 30 minutes? I didn't want to waste shock if there was something else wrong and it was vanishing for no reason
So by the strips own say so, 0, 20-50, 100 and 250+........ (or whatevs the values are), really doesn't tell you anything, now does it ?
The CYA is rhe most critical aspect of what we do. Without it you will have too many or too little FC. They both end badly.
You can't test FC reliably without a kit. Count to 20 with the test strips and it's a new color. Plus, they start degrading the moment you open the seal on a new bottle. Use the bottle to verify your garbage can still makes the ker-chunk sound.
Wait for your kit. You are throwing money away if you try before then.

Just make sure to add 5ppm worth of LC every evening to keep algae somewhat at bay.
