Water is green with some algae. Visibility is 12-16". Wondering if I should treat with chemicals. I don't want to be trigger happy, but also want to be proactive if things need to be addressed. 2 pictures are attached.

Brand new pond owner. Pond is 2/3 acre avg depth of 8 feet deepest is 12. Not managed for 20 years- literally nothing was done.
