Thanks I'll test again. Suppose I'm getting the same readings consistently; would this be of concern to the state of the plaster?

Hardness reagent was replaced this week, the other 2 bottles were left from last year.

After our first winter with the pool, and successfully running/using the attached spa (which worked great, I can discuss this more if interested), I opened the pool this past weekend and got it up and running. After refilling with about 1,200 gallons using rain water collected in a cistern, I...

I’d imagine so. For the replacement board I’m going to give it a good coating with this: 419E - Premium Acrylic Conformal Coating Really feels like something that could be improved on before it leaves the factory…

Good morning! After 3 months of using our new Raypak propane heater, I went to fire up the spa and noticed that it wasn’t heating with a “no pilot sensed” error. On opening the cabinet, I noticed the pilot was indeed lighting so i popped off the control and checked the flame sensor test points...

Good morning! It appears the recommendation for a plaster pool and SWCG is to keep CSI ‘slightly negative’ to prevent SWCG scaling. Just curious…what does everyone here aim for to consider their CSI ‘slightly negative’?

Just to follow up on this, I am now seeing a .5 PPM reading of CC...but also a drop in CYA (70 to 55). Don’t suppose these calcium contaminants could cause a CYA drop too? I cleaned bottles and re-ran the test twice, and I feel OK with my methods it’s a simple enough test.

7.4. App has my ideal range at 7.6 - 7.8. Maybe not the end of the world, but trying to commit to the process as much as possible 🙂. I’ve been out of that range before, just never towards the low end.

I didn’t notice it during the last test, no. As a side note, the need for acid has dropped dramatically since this started. I was using about 14oz or more daily (since the plaster was done mid April) to keep it in range and haven’t needed any since this started 3 days ago. Had to add soda...

Just wondered— did anyone ever get to the bottom of this? New plaster pool, have been maintaining with liquid chlorine since mid April until they turn on the salt generator in 11 days. I’ve been maintaining levels at: FC- 4.5 CC- 0 ph- 7.6-7.8 TA- 80 CYA- 70 CH- 170 Tem-...
