Algae bloom?
This is my 16 yr old RES, Squirtle. I built her this basking platform in her tank a time ago, so I fill her tank about halfway, she has a canister filter and just recently her water has been green like this after a few days!
I’ve been changing the water/rinsing the filter media twice a week and adding algae fix so idk what gives.
