Green pool, good chemistry please help!

[mjnorman]

Hi all. I've been using the tfp method for a couple years. Everything's been great. However, the past week or two my pool has been cloudy. We had a bunch of rain come in, and I actually had a leak at my pump as well so had to top off with water.

So I fixed the leak, and topped off my cya back to 80, and topped off my salt since it was low due to all the rain and added water. I also cleaned out my filter, it was definitely dirty and needed it badly.

I've had the pump running 24 hours a day and it doesn't seem to be getting any better. My stats are below, except for TA which for some reason my kit isn't registering, maybe the TA chemicals are bad? I bought the kit and end of last season so probably right at the year mark.

FC 4
CC 0
CH 75
PH 7.2
CYA 80
TA ?
Salt 3200


Does anyone have any idea what might be going on?

Sounds to me like at some point your FC had fallen below minimum which is a welcome invitation for algae to take hold. Once in your pool, you won't win the battle by keeping FC at the minimum for you CYA number. You'll want to read up on following the SLAM process to clear it.

Take a look at the link and post questions here if you have them.

for a cya of 80 your minimum fc is 4ppm your target is 6ppm
you are not leaving yourself any wriggle room

I was hoping since I have no CC and FC is staying up that it isn't algae. Is that really the only thing it could be?

Cloudy is algae unless you have suspended dirt (which your filter should take care of quickly) or you added a bunch of calcium chloride today.

You have algae. Follow the SLAM Process process. Do it soon, or you may have a full on algae bloom on your hands.

Thanks for the replies all!
