DIY Canister Thread #2

Okay so the basic design of my DIY canister filter has changed. I have decided to go with a 5 gallon bucket as my Canister instead of PVC pipe. It just seems alot cheaper and better for the job.

Questions:
If I want to use ADA tubing in and intake/outtakes. what is the best type to use?
what size can I use?
Where and what size barbs should I get to connect the tubing to the bottem of the canister?
How can I seal the tube in good?
Will two intakes and one out take going to an eheim universal pump be good? are those pumps quite?


will water work like this?

1 is one of 2 intakes
2 is would be some sort of hig surface area medium
3 is sponge
4 is filter floss
5 is pump intake.

I tried this once, fail miserablely but it was fun (I can't believe I am saying that!) I couldn't keep the lid to get an air tight seal enough.The cap poped and water spill. But if you are crafty with tools and knows hardware stores like the back of your hand you will be successful. DIY cannister is possible, but the price you are looking at between a retail one is about the same, cheaper if you are well planned out.

BTW... ADA tubing, aqua design amano tubing, is that what you mean? Howabout $6 clear tubing at home depot and get the same stuff?

From your drawings it will work. I don't remember the size of barbs I use, but a good size barb to let more water in so water outakes will be faster. I think one intake will do the job. Use the other one for easy water changes.

Get a male barb on the outside, and a female adapter in the inside, silicone the female outer ring in the inside of the bucket and that will be a 100% no-leak seal.

I have never use an eheim pump, but any magnetic drive pump is very very quiet.

I would just put both the in- and out-flows on the top of the filter. that way, you can use bulkheads to get a good watertight connection. For the lid, if you haven't thought of it already, I'd try a "gamma seal" lid. you hammer a ring on the top of the bucket, and then screw the lid on and off...supposed to be watertight.

Gamma Seals™ - US Plastic Corporation

If you really want to have the inflow at the bottom with hose barbs, I would try to "build up" the thickness of the bucket a bit using pieces cut from the side of another bucket...epoxy them in place or something.

Just my $0.02

(on a side note I have to add that as I was typing this I heard the sound of water dripping and noticed that my 10gal just started leaking at the seams )

Buy a good pump since youre saving money, hopefully, on your filter. In the future the extra GPH may aid you any diy inline gadget you decide later to try.

Good luck!

I like that thing.. wil it fit any 5 gallon? I would use silicone on the ring.. and how could I unscrew it if the out went tothe bottem? would bulk heads work? it would seem they cause extra pressure.

I am currently thinking this..

I think it would be easier to put the pump inside the bucket.

Didn't have much luck with Gamma Seals

I too attempted a 5-gal bucket canister project. I had a real problem with leaking through lids. Basically, the incoming water pressure was too great and it became too tight of a balancing act to match output with the input.

Lids:
As you may have guessed, the $3 lid from Lowes/HD leaked around the seal. I had even put airline tubing from the lid back up to the tank to help relieve inner air pressure. No go, I needed some sort of mechanical lock-down to help keep it sealed.

Enter Gamma-Seal Lid:
Originally thought to test it's sealing by filling the 5-gallon bucket with water, sealing it up with the Gamma Seal Lid and hold it up over my head for a bit. No leaks after 5 mins of jostling it trying to create inner turbulence. Set it on the ground upside down on the pavement for an hour; still no leaks.
But upon hooking up the of the incoming water lines and outgoing pump-line, once the bucket filled with water, it began leaking through the screw in cap of the Gamma Seal.

I gave up on my endeavor after the 350gph Cascade dropped down to $100. You may be able to apply additional sealer to the inside lip of the screw-in portion of the gamma seal, but I didn't get around to it.


Hope some of this info aids your cause.

You will never get a correct seal with this type of bucket.
The design is not made for.

I'm trying this one this week:



The lid is completely different:
