I’ve been thinking of building my own concept with a drain at the bottom feeding into a successive set of tighter filters, starting with chunk filter you can get at PetCo (looks almost like captain crunch) to grab the big chunks, then a stage or two ending in a layer of sand and finally a canister of activated charcoal packed between open-cell foam for chemical filtration.
Although I’ve also been thinking of using a household sediment trap instead of the rest of the first stages and then activated charcoal after that. And I’ve been considering using big rubbermaid tubs for the tanks.
I’m not going for “fancy” so much as “cheap and easy to build”, and having the series filters means they can be changed or cleaned separately. Using the sediment filter means just changing the filter cartridge. Problem is baitfish put out so much pollution I don’t know how long a folded paper filter would last.
Then again I suppose it could be washed…
So does anyone have their own bait tanks? If so, how did you acquire or build them?
