Is there any way to make you'r own filter cartidges, cheap?
I have 3 aquariums running on cartridges and soon getting 2 more!!
2 of my aquairums use Marineland cartridges and those are expensive!!
After awhile it starts getting really annoying with the prices since i don't have a job, LOL, it's like impossible at my age.
PLUS in my 20 gallon planted i don't want the carbon i9n the aquariums as i heard it kills plants!!
So is there a cheap way and what do i buy?
Do i really need to change cartridges once a month?
