So, I've decided to make a homemade canister filter.  I've dont
some research to take the best and worst from other projects...
These are some of the fundamentals-  1. Make sure it is easily
servicable, and yet watertight. Solution- Make it out of a large
plastic jar (like a peanut butter jar.)  2. Many builds end up
costing the same as an off the shelf canister. Solution- reuse
materials I have already and buy online... Peanutbutter jar,
cheap pump...Fittings will be pricey though.  3. Pump can break
prematurely if dirty water passes through it. Solution- put it
behind the filter material.  4. They are often ugly. solution-
who cares? I could always paint it, but I like the idea of it
being transparent (So I can monitor the media.)  5. Don't want
to have to 'prime' it eve
