I have had my pump sat 1600 rpm and the flow has been perfect, then out of nowhere it started showing red, so I had to crank it up to 1900 rpm for it to come back on. What causes that?

How is your filter pressure? higher filter pressure could cause the flow to drop. Adjusting the pump to a higher speed would then increase the flow. What kind of filter do you have?
Something that's annoying is they didn't install a pressure gauge. I had to call them and remind them to do it.. I was like isn't that the most basic thing??. This is our second pool in a year by the same people and I'm feeling like they really dropped the ball this time. We have a pentair sand filter. I will have to go look exactly at what it is. We did backwash and clean out filter and it went back to normal. I am very disappointed in this pool install as there have been several issues since they put it in 3 weeks ago.
So you were able to reduce the speed back to 1600rpm after you cleaned (backwashed) the filter?
Get that gauge installed and then backwash when the pressure goes 25% above clean pressure.
Pressure gauges here are great and easy to install. They are much better than what your pool builder will use.

The flow will go back to green then the next day come back on. We backwashed last night and it stayed green at 1500 then came back red and stayed stable at 1600 until just now and now it’s at 1750. I don’t get it. I don’t get it.

If backwashing allows you to run at a lower RPM, then that means the filter was dirty.. The only thing that will make your filter dirty is something in the water. Could be a lot of tree droppings, but most likely an algae bloom...
You need to show us some test results..

Yes, please provide test results and filter pressure readings. We can't help much if we don't have some actual data to go along with the need to increase speeds.
What happens if you backwash and then just set it at 1750rpm. Do you have any issues? At what speed does it always run without going into Red (low flow indication)?

No, it will not stay steady at certain rpms, so I'm having to up them every few hours to keep the flow on green.
There is so much dirt since they devoured our entire yard. We ordered a new silt/sand bag to catch smaller debris. It is supposed to come today.
They replaced the ic40 with the ic60!! Yay! Posted above are the numbers. Also had the gauge installed. When it’s at 1600 rpms it is 0 pressure. It does go up when I raise the rpms. Is that normal?
80,
With VS pumps and large filters, having very low filter is normal.. My pressure is about 1 lb but I have a 30 lb gauge.. with a 60 lb gauge you would read close to zero..

We just had an IC60 installed in a new pool last week and I can't keep the flow light green. It will turn green for a while then I'll go back out a few hours later or over night and it's red. What is causing this? Pressure of filter is 10 while pump runs at 2100 psi. What can be causing this? Numbers are all in range except the chlorine has dropped to 4 from being gone and not realizing the flow was bad. It is starting to get irritating.

80,
If you can backwash and get the flow light to turn green then your filter is just getting dirty.. When it gets dirty the flow will decrease...
If this is true, then you have a chemical issue with your pool water. Whether you can see it or not algae is clogging your filter.
If you put your multiport valve in recirculate, I'll bet the IC60 will run for hours with a green light. Of course your filter will not work, but it is a good test.
Thanks,

If I run on recirculate and ic60 stays green it’s a good indicator of algae or dirty filter?
