Has anyone tried this as filter media???

  • We are currently upgrading MFK. thanks! -neo

Amazed at the amount of people that use srubbies in their canisters. When you compare the surface area/cost of scrubbies to biomax, ehfisubstrat, matrix or bio glass. The scrubbies are far from cheap.
Bring back numbers and then we can talk :)

are you sure???? I think you would be hard pressed to fit 10 dollars worth of scrubbies in a canister since that is approx 60 scrubbies..... and with ehfisubstrat pro is running at 25 bucks a liter I think that scrubbies take the cake.;)
 



This is a specially designed sintered glass with an enormous surface area of 18,300 square feet per gallon.


Pot scrubbies 370 square feet per cubic foot.

1 gallon (US) = 0.133680556 cubic foot

pot scrubbies 49.5 square feet per gallon.


So if ya fill the biomedia baskets on a FX5 with scrubbies you'll have a whopping 75 square foot of surface area. Maybe a 100 sq. ft if ya smash them in.:eek:

Ya you could even go cheaper and fill the canister with gravel off the side of the road, but how much BB are ya gonna have.

Like I said comparing the media as surface area per cost. Not how much of either can ya stuff in you canister for a dollar.
 
Ok, so I took a new container of airsoft pellets and calculated the volume that the bb's filled, I did this by using an overflow container... You fill the container with water, until it overflows. You wait for it to stop overflowing, and then you put the object in the water and collect what overflows. I do not have any tools for measuring volume, as in graduated cylinders or flasks, so I have to do this the hard way.

I took all the water I collected and placed it on a postal scale (yes, I zeroed out the scale with just the container on it). It weighed 2 lbs 1 oz, which I have calculated to be 2.0625lbs. I know that one gallon of water weighs approx 8.35lbs, so I took the weight of my water and divided it by 8.35.

2.0625/8.35=.247005988 That is how many gallons of water I collected, hence the approx. space, in gallons, that 5000bb's takes up. We know that 1 gallon is 231 cubic inches, and 1 cubic foot is 1728 cubic inches, so there are 7.48051948 gallons in a cubic foot. Once we divide that number by the number of gallons that 5000bb's takes up, we can figure out how many bb's in one cubic foot.

7.48051948/.247005988=30.2847698 That is how many 5000s of bb's we can fit in a cubic foot. Knowing that 5000bb's has a surface area of 6.08160938 square feet, we can figure how many sq ft per cubic foot of bb's.

30.2847698*6.08160938=about 184.2 square feet per cubic foot.

Through all of this, I have come to the conclusion that, 1 cubic foot of 6mm Airsoft BB's has roughly 184.2 square feet of surface area.

This means that they have more surface area than bioballs (which clock in a 160in^2/feet^3), but are probably more expensive.

Looking at prices online, it is about $15 for 5000 pellets. So, it would cost about $450 for a cubic foot of these, ouch.

I am sorry, but either way you will have the same amount of BB. Just one way gives more potential for BB that the other.

Like chompers said in another thread, they do not know the actual surface area of the ceramic and splintered glass medias, it is purely theory.

Well thanks for crushing my dreams. can't you magically make them have more surface area!
Drill a bunch of small holes in them.;)

Yah... But it would look neat :D

I think fluidized bed filters look even cooler though... And are better/cheaper.

How about converting that to a FBF and getting an aquaclear powerhead (ac70 should work) to power it? Just change the item number at DFS to CK instead of CD and you can get one for 27.99. That would be cheaper than buying 2 containers of BBs

Or just leave them be and pay through the nose for something that looks cooler, but doesnt work as well as, pot scrubbies.
