I haven't been over to my Mother in Law's house in a couple months, but she lives within a couple miles and my wife went over there this week and reported back to me that her pool was lime green. She knows how "particular" I am about our pool, so I have been voluntold to help out.
She has an in-ground plaster salt water pool.
Apparently the pool guy wants to replace her pump tomorrow so I guess there could be a pump problem. She has a salt pool and when I went over there tonight the panel had a warning light and the readout said the salt cell wasn't working and the salt level was extremely low. I don't have a salt pool so I don't have any salt tests. Are there any salt tests I can buy locally that would be TFP approved?
Here is what I did find using my TF-100:
PH - off the charts high - never seen that shade of purple before
FC - 0
CC - 0
ALK - 60
CH - 675
CYA - I'm guessing 0. I could still easily see the dot when the tube was completely full
I'm trying to find out the pool capacity from my mother in law, she wasn't home when I got the water sample.
The water is definitely green, and my wife mentioned that the pool guy apparently wants to do a full drain to clear it up. That seemed a little extreme to me.
Seems to me she obviously needs a SLAM, and potentially has some equipment issues. I've personally been following TFP methods since early in my pool's life so I've never had the pleasure of going through a SLAM before. I'm wondering, do I need to adjust ALK first before I try to get the PH down? I know getting the PH correct is important for starting a SLAM so I want to make sure I get that right. What would you all recommend for ALK target to get started? 80? Higher? I'm not as familiar with salt pool best practices.
When I was there I could see the pump was running and I could see the water was moving, so I wonder if along the way between my mother in law to my wife to me if the word pump could have been substituted for filter. I believe she has a canister filter.
I also noticed her equipment pad was pretty wet when i was there, not sure if the pool guy was there earlier and got everything wet or if the sprinkler system ran recently, but I'm hoping there isn't a leak. We are in Texas and it hasn't rained in a while, so any other sources of water would have been long gone by now in this heat.
I know that's a lot of information in one post, and it will probably be a couple days before I get the full story on what is going on.
Hopefully together we can get this thing sparkling again.
