Okay, so a few weeks ago, I went bare. I took all of the rocks out of Gregory's tank. However, after I did this, I remembered that bacteria lives in the substrate. So his ammonia levels spiked, and I'm back a few steps in cycling the tank.
And then I found that I hated the look of it, despite how easy it had become to clean, so I want to put substrate back in and purchase a substrate vacuum.
Right about now, I'm considering sand as a substrate, since it is so fine that pretty much anything will sit on the surface of it, instead of sinking through to the bottom. Has anyone gone this route? If so, can you tell me how its worked out for you?
