Help for diy fluidized bed filter
- Thread starter hangner
- Start date
Just so I'm not confused the diffusers are what they call laterals right?
and does anybody know a good link where they have good prices

with the diffuser bowl the intake goes to the bottom of the fbf then the diffuser bowl is shaped round. there is a gap of 1inch in between th bowl and the intake. also the bowl has vents or raised parts that are shaped outwards and are bent a bit like a turbine. basically they turn the water to the sides but they are curved so once the water hits the sides and isnt guided anymore it spins and creates uneven water movement wich makes for a more efficient fluidized bed
No-one has said it yet, so I will... 10"!?!? that seems a bit on the excessive side to me. a 2.5" x 2 foot sand filter like you're building is enough bio for a decently stocked 200-300 gallon tank. Keep in mind that the amount of sand, and hence the amount of bio goes up with the square of the diameter... so you're talking about running 25X as much bio as a pretty decent sized bio filter. You'll also need to run 25x as much flow to fluidize that much sand. I'm no expert, but I think you'll need to plan on running a pump on the order of 10000 gph to properly fluidize that size of a filter.

Oh. Sorry
Well, I'm not saying it's not possible, I'm just pointing out the dimensions we are discussing here. If this is what is really required, then fine, go for it - this is after all a site dedicated to fishkeeping overkill. However, you might be better off with a 4" or 6" FBF, which will reduce the cost of building and running it pretty significantly. There is after all, no point in having biological potential you will never fill.I would use a baselayer of gravel, that would diffuse the water alot and make sure there arent any deadspots in the sand. I'm also with everyone else on the 10" diameter tubing. I think you'd save yourself alot of $ if you went with 4" or 6" and wouldn't lose all that much filtration.
Dont know if u guys completely understood:
the tank is going to be 900g but i am basing myself on this system except mine wont be as compact (system 5000 marine)http://www.tmc-ltd.co.uk/commercial/2500_5000-filtration.asp
the system is rated for 5000 liter as you can see this is a bit too much but if i decide to have another sw tank i can just add a return to the filter, as for the moment it is just extra filtration
the fluidized filter is the one that comes with the kit and the pump is something like 80-100 gpm
thanks for the info on the diffuser bowl but i dont think i'll be able to make that since it is a bit complex!
i'm wondering if 2 6" filters would cost less than 1 10"
how much water is 60 lbs of sand supposed to be enouth for? cuz i calculated that this filter holds that much(60 lbs of dry sand fill it to max 1/3)

Just so im sure i ve heard that these filters form a "block" of sand when the power is out.
is this true? if so what do u do?

Wow Great diagram. And just a suggestion for the Power you can probably make use of an Uninterrable Power Supply (UPS). I am currently using one for the canister filter in one of my tanks. It's a 700W model and with just the canister running i get about 4 hours on the battery. Happens a few time in my location already.
That should help that block of sand!! i think?
As for the extra filtration that will always come in handy when your want to add more fish as the loading would be very light on the filter initially. good luck with your DIYs. Lots of item i see..
