I would suggest soaking it in a 5 gallon buckets of water with a cup or so of bleach added. This will kill all the algae and release most of it from the pump. Follow with a through rinse with water and you should be good to go.

My Little giant wgp-65-pw has tripped my gfi repeatedly. any idea why? No shorts in the cord are apparent

if a pump connected to a gfci outlet trips , then the gfci has detected a high resistance "shortage" inside pump and has disconnected power , this "shortage" can be nearly in detectable from human standards(shock) , but gfci picks it up
most likely pump seal has failed and water has gotten inside pump !! it only takes one drop to do this !!

Problems priming little giant pw-95 pump

since this is a waterfall pump , id try using a short piece of dish hose and see how it flows water then , if it works there then id say your demand to lift is too great and a larger pump will be needed to lift that high ,

also note on waterfalls id leave out the ck valve on dish pipe , i know it takes longer to reprime itself each time , but that reverse flow action cleans your intake screen each time it shuts off

I cleaned the screen, and the impeller is working however the little giant pump WGP is still not pumping water.

You may need to take the bottom of the pump apart and check to see if any thing has gotten through the screen and clogged the impeller.

Little Giant pump WGP-90-PW trips GFI circuit

You might have 2 problems. The GFIC might be wired wrong or the pump wirng might be compromised with moisture. The noise issue? Are you running this unit without submersing it? They will burn out if you do. To get a more accurate running sound, submerse it with a flexible pipe so you can run it in a 5 gal bucket without losing the water.
It's possible a bearing is burned out.

Pump plugged in to grounded receptacle trips the

If by "trips the breaker" you mean the GFI then you are leaking current to ground, GFI's trip when there is an imbalance between the current going to the motor on the HOT side and returning from the motor on the NEUTRAL side, if it is tripping the GFI it is likely the sign of a failing motor.

Anthony filter system faulters after short while of running

If you have alge in your water it builds up in the filter and stopps it up rite away. You will need to take the filter apart again and hand clean it out again. but you will need to super chlorinate the water and kill all the alge before you start the pump or it will plug again. If you run it like this for any amount of time it will crush the grids, so be sure you kill all the alge.
