Penn-Plax Aquarium Cascade 1000 Canister Filter for aquariums up to 100 gallons $49.35 at Amazon after the $15.59 coupon on the product page.
This is quite a good price for a decent canister filter and would be a great upgrade for anyone with a hang-on-back filter.
Some canister filter tips from the experts:
- For additional filtration power, fill the media baskets with good biological media like biomax, bio rings or sponges. (or for a cheap DIY alternative, try those cheap nylon pot scrubbers you can find at the dollar stores!) Activated carbon is an alternative for chemical filtration, though some hobbyists debate it’s efficacy. Save money by buying it loose and bagging it yourself.
- Also, add a prefilter sponge for extra filtration and to keep small debris out of your filter, allowing you to clean the media inside less often. It also can keep smaller fish, shrimp and babies from being sucked in to the filter!
- You might want to put some floss or a pad on the sides of the baskets, since some water can make its way around the baskets and avoid being filtered. Floss will block that easy flow and add filtration.
- ignore the manufacturer’s advice to change your sponge pads often. They only say that to keep making money off of you, and you’re just throwing away all that beneficial bacteria you built up! If you clean the sponges in tap water, they should last for years, if not decades. You’ll probably want to clean and change the floss pads though.
- Also, NEVER clean your media in tap water, because the chlorine and chloramine in tap water will kill the beneficial bacteria that does most of the filtration. Rinse the media with tank water.
- Always take filter manufacturers’ aquarium size recommendations with a grain of salt. Those numbers are based on absolutely idea conditions which won’t exist in your tank. Always get a filter for a bigger tank than you have. There’s no such thing as too much filtration in an aquarium.
- Google "pimp my filter" or search on YouTube for good ideas.
