Old Pool to a New Owner

If you think to do so, I'd love to have you post a follow-up in a month or so.

Will do, thanks! Can you verify my account?

done.

Well it hasn't been quite a month yet but I'm getting algae growth again. It's been raining for 40 days and 40 nights it feels like. Right now my FC is 3.0 and CC is 0. I just opened the housing to see the filter since I last posted and the image below is what I found.

The psi is still at 4.

Also, I'm not sure on how often I'm supposed to add chlorine or the proper level. I've been adding a bag of that shock plus every 5 days or so until it's all gone and then I'll purchase something else.

I'll pick up 6 gallons of bleach again and put it in tonight unless I hear otherwise.

If you are getting algae, then it is because you are letting your chlorine get too low. How often are you testing the water? Run a set of tests with your K-2006 and post them along with your volume. What are the ingredients in the shock plus?

How often should I be testing the water?

Added 6 gallons of bleach Friday

Right now:
3.9 FC
0.2 CC
CYA 54
4 drops R-005 for ph 7.7
Volume 14,000

So with these results it looks like my chlorine level is ok but I need to lower my ph by adding 2qts of Muriatic Acid?

Adding 6 gallons in your pool all at one time raises the chlorine level by 35ppm!

A better plan until you get a feel for your pool's behavior, is to take 5 minutes and test every evening. Also, with a CYA of 54 (how did you get that number?), your chlorine is on the low end of acceptable. (Take a look at the Best Guess Chlorine Chart in my signature below.)

What was your actual pH (before the R-005)?
