I am glad that this worked for you, but I can say from experience that this is not the case in the section of Citrus Grove I am in, built in 2021.

The developer supplied 30 low flow oscillating heads. Opening them up full throttle did not fix the problem, fits because they allow so little water through, but also because what was on the screen was an amalgam of green slime and sand.

The developer contractor did not entirely think through the overlap situation on my lawn, so I tinkered around with replacing some oscillators with sprays. Again, opening them all the way up did not work, for the same reason. The sand reinforces the slime and it becomes a tenacious substance.

I have 2 out of 30 heads high capacity high flow sprays, maybe those would work as flushers, but installing them is very tricky to balance with the other heads, they would have to be at the bottom of the loop, and could only at best help unclog the zone they are installed on ( I have four zones ).

So I am not a paid shill, just saying, that irrigation filter is worth every penny.

Citrus Grove? That would be one of the southern areas that I mentioned in the paragraph that you did not include.

Filters can’t hurt but some do not need them. Location matters.
