Hey guys...I'm thinking about sticking a tub outside with water and some slate just to get algae growing on it then stick it in my tank for my pleco to nom on. Anyone see anything bad that could happen with this? I got the idea when I was letting a bunch of rocks soak outside in a tube just to make sure they didn't have soap residue on them and I forgot about them for a couple days and they were pretty well covered in algae. Washed it off without thinking about it, but I could be letting my pleco's eat that stuff haha
On another note...my brown bristlenose pair layed eggs again a couple weeks ago or something and now I got a bunch of pleco fry again haha...gotta love it.
