bassman843 Posted February 28, 2007 Report Share Posted February 28, 2007 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.

dampeoples Posted February 28, 2007 Report Share Posted February 28, 2007 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.

bassman843 Posted February 28, 2007 Author Report Share Posted February 28, 2007 it just doesn't seem like the air is coming up through it like I've seen on other beds Quote Link to comment Share on other sites More sharing options...
dayooper Posted February 28, 2007 Report Share Posted February 28, 2007 You may want to try a bigger air pump. The air pressure and volume may not be enough. Quote Link to comment Share on other sites More sharing options...

reeves Posted February 28, 2007 Report Share Posted February 28, 2007 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.

kelly Posted February 28, 2007 Report Share Posted February 28, 2007 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.

bassman843 Posted March 4, 2007 Author Report Share Posted March 4, 2007 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 Quote Link to comment Share on other sites More sharing options...
tankar Posted March 7, 2007 Report Share Posted March 7, 2007 do you poke holes in the paper bag if so what size and how many Quote Link to comment Share on other sites More sharing options...
kelly Posted March 8, 2007 Report Share Posted March 8, 2007 No holes. if you take the bag and put it on your lips you can blow threw it. And it is the lunch sack 2"x4" and 8" tall. I also use alot less air than i did with the coffee filter. Quote Link to comment Share on other sites More sharing options...
bassman843 Posted March 13, 2007 Author Report Share Posted March 13, 2007 I looked at the one they have at janns net craft for $120 mine looks about the same work about the same they did have a bigger pump on it.I asked and they said the fabric was like $500 a sheet that they use.it wouldn't let the powder through but the air would.

akriverrat Posted March 13, 2007 Report Share Posted March 13, 2007 hate to sound like a skipping cd but im telling you guys an allergy pillow case is working great for me. i dont get any powder in my air chamber and the fabric lets the air through just fine. im using an aqua culture 20 to 60 gallon aquarium pump and had to throttle the air back on my two inch by six inch cup. this pump has two air outlets so if needed i could hook up two brass fittings one on each side of pvc coupler and run a pretty big fluid bed. i bought one 240 thread count pillow case for (5.99?) and have only used a six inch circle of it so far. you can make alot of fluid beds out of one pillow case. i have used my fluid bed probably 100 times so far and havent had a problem. just trying to help. john Quote Link to comment Share on other sites More sharing options...

LedHed Posted January 29, 2008 Report Share Posted January 29, 2008 Drich Yes, but would recommend using an in-line air drier. Quote Link to comment Share on other sites More sharing options...

davycrockett Posted January 30, 2008 Report Share Posted January 30, 2008 Speaking of materials for the membrane, has anyone used a vaccum cleaner bag? Not the whole bag of course but a piece big enough to seal the bottom of the cup. Quote Link to comment Share on other sites More sharing options...
