I have a summer waves 18 by 48 pool. I recently purchased a intex sandfilter 3000. The pump is pumping but it's pulsating like there's air somewhere in there. My pool water now is starting to get green and I don't know what to do.
Yes I didDid you bleed the air from the system before turning the pump on by unscrewing this little knob until water comes out?

Welcome to TFP!Can you post a pic or two of your pool and the equipment pad so we can see the filter and any lines, connections, and valves?
Refresh my memory on the purpose of that valve just before the pump. Is it a shut off valve or something else? Is there any way you can connect the hose to the pump without that valve to see if it's the problem?
I remember fighting with that skimmer- mine was round & the “basket” was weird. If I recall I had remove the weir door for it to do right without sucking air unless the water level was just perfect. That skimmer was designed to only have a little fish tank pump pulling water through it.When I first started before I hard piped and valved things, I would have to manually fill the basket to the brim before turning the pump on. There was not enough pressure for the water to naturally flow and fill it.
I'll give it another try I . thanks for helping I'll let you know what happened.Have you backwashed & rinsed the new sand well? At least a couple times. This will not only clean the dust from the sand but also help get the system full of water. *before moving the mpv handle be certain to always turn the pump off.
You can try pressing down on the handle with the pump off to help let air escape the filter & help get it full of water (i have to do this a few times upon the first startup of the year since the filter is dry)
along with undoing the grey release on the pump basket to ensure the pump basket is filled with water.
Basically do these things then turn the filter on a minute, turn it off & repeat
Other important things to try: lubricate all orings on all connections including the pump basket lid.
