SLAM help & super high phosphates

[caitym]

I’ve got a 14,500 gallon fiberglass pool that is typically salt, but we’ve let to put the generator back on. We just took off the mesh safety cover two days ago and the pool was completely green as expected. I have the recommended testing kit recommended here and found the ph high, so I put muriatic acid in to lower it enough to SLAM. I added 8 gallons of liquid chlorine and the pool cleared up within hours. It’s still cloudy, but clear. The CYA level is not even 10. My husband went to buy stabilizer today and wanted to check my numbers with the local mom and pop pool store. They said cya was 15, but phosphates are 1200. They said use Orenda PS-10000 before doing anything else. I’ve been adhering to advice on TFP and I know phosphates aren’t really important. However, I wanted to touch base with you all to see if you would treat for phosphates and also if you would adjust the cya first? Chlorine is still where it should be. Thank you!

Always adjust CYA to 30 before SLAMMING. I'd suggest you print this out and keep it with you and follow them...Link-->SLAM Process
I would not treat the phosphates. Not necessary.

Thank you!! Pool looks great today! I don’t know how I missed the cya being so low. That test drives me crazy. I’m now at 40 cya and total chlorine with the dpg test was 14 with no combined chlorine. Is it safe to swim? My kids are dying to get in before it gets cold for the next week!

Go swim. If you can see the bottom of the deep end and FC > Min and FC <= SLAM level FC, it is safe to swim.
40 CYA, your SLAM level FC is 16.
Did you print out the instructions?
