New plaster

[carpenteroasis]

Hi, We're located in Maryland and have been pool owners for 15 years but still feel like we haven't figured it out. We just had our old Sylvan pool replastered. It's Day 8 and the calcium hardness is 350. The app says to remove half the water. I just spent $2k on that water. Any other options? thank you

First, ensure that when you defined your pool you chose plaster for Pool Type. Next, check to see what your Target CH is set to - should be around 350. Regardless of whether you set it up with liquid chlorine or SWG, the recommended hardness levels are the same;

CALCIUM​

ACCEPTABLE MINIMUM:​

250-350

IDEAL:​

350-550

ACCEPTABLE MAXIMUM:​

550-650

So 350 is at the lower end of the Ideal range. If the pool is setup correctly in the TFP app, then it shouldn't be asking to remove any water. If everything is setup correctly, then something is wrong with the app install. I would try uninstalling and reinstalling.

Regardless - if your CH is 350 you don't need to replace any water. I didn't replace mine until I hit 800 several years ago, about two years after the pool was built. Since then, my pool has cured enough that it's remained fairly constant in the 350 range.

Ok thank you very much! The pool company said 200 CH at the highest for the first month, so that's what I put in the app. I'm glad 350 is ok!

See the NPC startup guideline - you are fine with any CH over 150ppm.
