Yah, I actually want it to grow fast enough to partially feed my mystery snails. I switched the snails to a different tank today and moved my loaches to the tank they were in. The loaches were moved to eat all the pond snails infesting the snail tank. Well the tank I moved them into has a lot of algae in it and guess what. The snails have not stopped grazing on it like a heard of cows for over an hour. They love it and are cleaning the glass beter than it has been for quite a while.
The question is, is there any real way to grow algae, the soft stuff, fast enough to actually feed them or would they keep the glass too clean for it to really grow very well?
If they are going to eat it too fast, what is the best way to grow it on rocks or something else without putting it out in the sun?
Would a glass jar in the window grow any kind of actual algae or only make green water? ( I know, algae bloom/green water but I can't feed green water to the snails. )
