Bullsbug Posted March 10, 2008 Report Share Posted March 10, 2008 I've built a fluid bed and I am having a few problems. I used the lunch bags as my membrane for my cups and it seemed to do fair with the black paint but the brown would not fluff up right. Also how do you attach the membrane to the cup, be it the paper, pillow case or coffee filter. My air source is the aquarium bump with the two outlets.

Gloomisman Posted March 10, 2008 Report Share Posted March 10, 2008 Make sure your paint doesnt have moisture in it. THis is the #1 problem I've found. Quote Link to comment Share on other sites More sharing options...
Sixgun Posted March 10, 2008 Report Share Posted March 10, 2008 I attach using Elmers Glue-All. Another way I read about on here is to take a test cap and remove the "inner part" leaving only the flange. Cut your circle of paper, position over your cup, put "flange cap" on and press in, cut off excess paper. Ray Quote Link to comment Share on other sites More sharing options...
mickalo Posted March 10, 2008 Report Share Posted March 10, 2008 I've heard from other fluid bed users, that a coffee filter works good too, like using the paper. Mike I attach using Elmers Glue-All.

pikeman1 Posted March 12, 2008 Report Share Posted March 12, 2008 I use a filter paper from work for media and it works great even with white. I just put a little silicon on bottom of cup, put paper on lay on flat surface with a weight on it and let dry, cut excess off. Quote Link to comment Share on other sites More sharing options...
Spike-A-Pike Posted March 12, 2008 Report Share Posted March 12, 2008 I think I did the same as pikeman1; used a paper bag with silicon RTV to keep it in place. Quote Link to comment Share on other sites More sharing options...
mikel7@mac.com Posted March 12, 2008 Report Share Posted March 12, 2008 I don't use any glue. I used a cap end for my bed and then the pipe fits inside holding the filter. You have to smooth and round off the edge with fine sand paper or it will tear the filter. Quote Link to comment Share on other sites More sharing options...
Hawgwild Posted March 13, 2008 Report Share Posted March 13, 2008 I use 3" PVC couplings and glued the base to a light piece of particle board with my air connection drilled into the bottom of that below the center.... Then just cup a coffee filter over a piece of 3" PVC and push down into the coupling....add powder and your good to go... I've got 5 made up and all work with no problems...if it has set up a while I just turn my air on and stir a little to get it flowing better...
