How do you know when to or how often do you clean an AGP cartridge filter (not intex)? Brand new to this type of filter, we had a sand one last time. Pool was just put in and filling now, but I want to get ahead of the game on maintenance and know when to do things.

We recommend cleaning any type of filter when the pressure rises 20 to 25% above the clean pressure.
Have you already invested in one of the recommended test kits?

Order the tf-100 from tftestkits.net ... it is the best value. SpeedStir is a nice addition.

I have a cartridge filter. The filter gauge has two arrows. One points to the clean pressure and the other points to the pressure when I need to clean it. Also, if you have a spa or other water features, you’ll notice the flow decrease significantly when it is time to clean the filter.
Are the lines 10psi apart? Because that is waiting way too long and not what we recommend.

Your pressure is below the green line 
You know the idea was to turn the knob so the green is on the clean pressure, right? But waiting for the red line is too long.

I saw that too. I just cleaned it about 2 weeks ago and set the dial to where the green line is. Not sure why the pressure would’ve dropped, unless one of the kids was playing with it.
