Super lol. I just tried to test it and got nothing but bubbles so im gonna tweak it still no pics cant find my sd.any clue how the lift works?i assume that a vac is made from the rising air but i have 0 movement of sand.So does it suck or blow the sand
I think my sand is too heavy it is a reef sand bag and i believe it is artificial, but any way i have it out of the tank and the sand is pack in there .Im gonna give it its own pump to see if it needs more power
i would assume that the sand would sit on the air stone and when it lets off air it would disturb the sand. and consequently the bubbles rising upward would create a current that would carry the sand upward
