I have a theory that the irrigation heads that recess too far into the soil (vs those placed slightly above) have a tendency to collect sediment (when not in use) thus clogging filters and getting sediment trapped in the lines.
Can you comment ?

The algae has little to no impact - it’s the sediment - see photo. There’s an incredible amount of bits, pieces and live things that are captured by the filter.
If u have filter screens in your irrigation heads - depending where u are located - you’ll be getting the same junk shown in the photo.
The average homeowner is not going out every few weeks to clean a bunch of filters. Not cleaning means reduced water flow.
My opinion - the above ground filter system is a must have.
I can only speak to hunter spray heads. Let’s start with a closed head. The spray head is kept closed with a spring. The seal between head and body is snug.
If a bunch of dirt cakes over the closed spray head - there will be no interference.
Water pressure causes the internal body sleeve (what the spray head is connected to) to raise up. At the same time water pressure is spraying out of the head holes as it pops up. If dirt is present the water force will blow it out.
When the watering cycle ends - the sleeve is pulled down with force along with remaining water spurting out of the head. In essence - it will close clean.
I don’t view that scenario as a problem.
