built my fluid bed tonight doesn't seeem to be working right.I took a 3" pvc coupling glued a flat cap at one end and put a coffe filter and a piece of 3" pvc on the other hooked up the air and it just doesn't seem to work right.the air pump is for 5-10 gallon tank .I used a screw value to hook up the air would that make a difference.

Define 'not working right'

Also - who's powder are you using? Does it have flake? Try removing some of the powder from the cup, I've found that some powders are lighter than others, white and black (from CSI) tend to be the most finicky for me personally, try a different color, see if you get the same results.

it just doesn't seem like the air is coming up through it like I've seen on other beds

You may want to try a bigger air pump. The air pressure and volume may not be enough.

There you go man, Mr. fluid bed has spoken

I've had that happen on mine from time to time. Problem was the cup wasn't seated deep enough and some air was bleeding around it rather than through it. Try pushing the cup in a little deeper, it may help.

use a brown paper bag for the filter the one you get from the store. less boiling, less air and less mess. i have tried the coffee filter and made a big mess. had to plug the filter before it wound work right.

I'm going to try later and I'll let you know what worked

when I first started I tried the black it worked but not liked I hoped I switched colors and worked alot better.The paper bag thing worked but I think it would be better for bigger pumps.thanks for the help

do you poke holes in the paper bag if so what size and how many
