Mag a tad high but more associated likely with alk, water flow and salinity. Verify your readings, taking a sample of your water to a trusted LFS and have them test water and verify your readings and to compare with your readings

I will try tested with DSR reference all my salifert tests. Thanks

My readings are fine. Any other thoughts? sal 1025.

Alk hasn't risen lately, has it?

I'm not a monti cap expert but I have two friends who have massive caps and both have seem the same issue when either nutrients were allowed to fall too fast or they let dKH climb. Both dont allow dKH over 8 because they get plate rot.

Thats right. My Kh was 8- 8,5 but for a reason in two weeks for my mistake( Trying to race ca ,i race Kh and get to 9,5). I hope this is the reason. Thanks guys

I think its both. Raised kh and i was trying to raise redox putting second catalist to oxydator.
