that pic clears up alot.. i attempted a DIY FBF, but could not get the upflow to disperse evenly. It worked OK but was built small scale as an experiment. Thanks Li.
Inside of a FB900 Lifegard Fluidized Bed Filter
- Thread starter neoprodigy
- Start date
These fluidized bed filters seem like alot of hassle. What are the advantages over other filtration?
Great bio filter that can change quickly to demand, and because they are bio only they need basically no maintenance. Downside is they use up a good deal of oxygen.
I want to add one to a turtle tank where the bioload changes quickly. Then I wont have to worry as much about the biological filter when cleaning canisters often because turtles are messy.
hmmmmmm.... Im going to do my homeowrk on these FBFs. Im going to be gone for all of next year and part of this year so tank maintennance is going to be my wifes job. If these are little to no maintenance then they may be the ticket!
the key is to make a "cone" shape so the sand will suspense evenly.. since trying to make a screen bottom like the fb900 will be alot of work... if you make a cone shape.. there will be more "water pressure" on the bottom.. check these

I see.... i had a cone shape in my design, but the flaw was that it was inverted..lol. the cone was inside the cylinder (media chamber) and the logic behind it was to keep the sand from falling back thru the in-flow tube on shutdown. The result was a lot of dead spots around the cone.
Is there a sticky or a link where I can read up on the FBF concept. I want to learn more but dont want to keep plaguing the thread with questions.
Any help is appreciated.
