PICK YOUR OWN
I been using a pump like this one, I added 5ft of hose tape the last couple feet of the hose to a length of bamboo so I don't have to bend over and can reach planters in back of the room I can stir the 5gal bucket of nutes with the suction end only real downside it runs on D size batteries pump lasts a year or two depending on the on and off switch pays to add a little dielectric grease to the switch
