Is it possible to "farm" algae for supplementing the diet of algae eating fish?
I was thinking of using my old 2.5 gallon tank to set up a farm of sorts like this:
1) Acquire several sheets of slate, my LFS has some that's quite thin
2) Add enough substrate so that the slate can be stood up on edge, and then just rack them in with a little space between them
3) Fill with tank water, or at least dechlorinated water, put the lid on, and set it in the window.
I'm thinking that the plates of slate can be removed as needed and added to my existing planted tank to make sure that my BN Pleco gets enough algae to supplement his wafers and veggies.
Would I need to add the filter for water circulation, or is standing water better?
Would I be likely to grow anything useful, or am I going to grow a tank full of inedible scum?
Would I be better off to just run my tank light 12 hours a day?
Opinions and ideas wanted and welcomed!!
