DIY Internal Canister Filter!!!

wow, that sucked the fun right out of this thread.

There is at least one more reason to DIY. Parts laying around from other projects/broken stuff can be recycled (with no cost for gas, amortization of the vehicle, tires, no increased taxes due to unnecessary and frivolous use of the road etc.):rofl:
 
Seems like a neat idea, maybe I'll try it someday. But its not exactly attractive to see a Jiff jar filled with biomedia in a amazon biotope :D
 
Not rain on anybody's parade. But the cost list above is incomplete. It doesnt include the cost of gas to run around to all the stores to get the stuff, nor the wear and tear cost on the car, It also doesn't include the value of the time involved. You can earn 8-10 bucks an hour flipping burgers. So if you spent 5 hours on the project- including getting everything, then there is another 40-50 bucks of cost.

My guess is the true cost of the diy filter is really over $100, Checkout what equipment you can buy online for that- even paying for shipping.

There are only two reasons i can see for doing anything DIY. The first is because exactly what you need isnt available premade. The second is because you enjoy doing it. It is very rare for anything DIY actually to cost less than premade.

correct on the gas and such part, but i combine trips when doing errands and going to the fish store is aprt of those trips. plus, it was done on my free time at not time off from work (dunno where that idea came from), so there was no work time lost in wages...

diy is great for the satisfying, primal reason that YOU did it, not a company or someone else. in fact, i hate to kill anyone's notions, but the world advances by innovation, not by buying the status quo.
 
You know, this really isn't nearly as expensive as the OP makes it out to be. You can similarly use a powerhead, a soda bottle and some media, and it shouldn't total more than $20 and a few minutes. I don't think the "value of time" should be counted in since it can be done in our free time. No one's going to take 5 hours off from work to do this. Although I guess the weakness in this is that it's virtually the same as every internal filter I've ever seen.

yes, that is true!!! i built one just like that! check it out:

there is one BIG differrence though with the other internal filters and mine- you can customize the one i made anyway you wish and there is lots of space to be used too!!!

to be honest, i had the jiff peanut butter jar, the powerhead, and the twine already. i just factored them into the cost so i would'nt leave that out...

sorry about the double post, i wanted to reply to both posters but dont know how to do that in one post, if you follow me!!!
 
I made a DIY very inexpensively. I took a travel coffee mug that had the lid that separates into two parts. Took the top part off. Then I took an air hose and shoved it down the middle of some pot scrubbers from the dollar store, attached a one inch air stone. Dropped some rocks in the bottom to give it weight. I put it in the tank, let the cup fill up with water. Attached an aerator. Walla an instant filter. Everything is forced down to the bottom of the cup and has to come up through the pot scrubbers to get out the holes in the part of the lid that is on. I wouldn't use it on a heavy bioload but it works. Water is crystal. Am 0, Ni 0, Na 25.

hey, thats pretty cool! an air-driven internal filter that uses those pot scrubbies! post pics of it plz!!!

Most internal filters can be customized just as easily, since they are basically a canister attached to a powerhead. Still, good job on coming up with a DIY project that I don't think anyone else has thought of yet.

At the bottom of every post, to the very right, there's a "" button. Clicking it will include that post in a multi-quote.
 
I stuck a rock on top to make sure the crayfish didn't knock it over. It is a 10 gallon tank. You could use a larger cup as long as you have 2 holes coming out the top. One for the air hose, the other for water and air to come out of.

I think what TTA was trying to say was that for the time you spent making this thing, you could work a few extra hours and have enough money to buy something premade. This may or may not be true..but the issue is that, with my DIY projects, I usually end up working on them an hour here, an hour there. No place is going to hire me to work an extra 2 hours a week to fund my hobbies. And at my regular job, its salary so its not like I can work a few hours of overtime. Yes, sometimes DIY ends up being more expensive than prebought. But, by doing it yourself, you are a) forced into a deeper understanding of the principles involved, b) get something that may fit a niche better than something off the shelf, and c) most importantly, have some fun building something. I know some people might not enjoy tinkering around with stuff like this, but I and many others do it just for the sake of having fun building something rather than strictly to save money.
