Best trick is hillbilly, you ready for this.
I got a 26g sand tank, beautiful white sand.
I take a chopstick or a solid wood ruler no metal or paint on it and rubber band that to my vacuum end.. you stir the sand while only getting the crap off the top. I did mine yesterday half butted so its not spotless but I got atleast 85% of the crud out.
I add sand by tupperware, do the rinse then while I am doing a PWC and the water level is down I then ad the sand but lowering the tupperware to the top of the sand and slowly tilting it till the sand pours out. Then after anything/everything settles( less then 30 seconds) I move it around with a hair pick to give it a combed look. It looks nice till the kuhlis figure out what I did and use the comb rows as drag strips.
Also if there is any crap left-over, I take a brine shrimp net to it and sift it that way, the weight of the wet sand is enough to pull it thru with a little jigging help( jig= up and down in fish world) I get the crap but not the sand, the holes are big enough to let the fine sand thru yet small enough to trap the debris( kinda like how gore-tex works but different in our case)
I find solutions to problems, I improvise and make things simpler as my wife( not a sexist comment) is lacking alot of these skills, im lucky she knows how to pump gas. Im not being mean to her or women she just doesnt understand this stuff yet she can make ugly girls hot in no time.
It just takes patience. I got white sand because I like the clean look and like the challenge of keeping it clean.
