DaPlantMan, I recall when you set up your classroom tank. I think it was about a year and a half ago, right?
Well, enough with niceties, the tank is almost cycled. We did our final check on it yesterday. We dropped two cap fulls of ammonium sulfate into the filter, and by the time we pick our son up from school this afternoon, there should be zero ammo, and zero nitrites.
Our ph is stable, but it's stable at 8.1! I'm considering burrying a little coffee and peat moss in the soil to bring the pH down a bit, as eventually I would like to breed something more difficult in the tank for the kids. The little ones will get a kick out of guppies breeding, but the older children I think would really like watching the spawning rituals of bush nosed plecos, or german blue rams.
Either way, all the children are getting very excited about putting some fish in the tank. I'm going to start with some inverts, and if the light ever gets here from Amazon, I'll put some plants and mosses in the bottom so the critters can hide from the predators. So, since folks like to see plenty of pictures on here, here you go.
Also, they charts we have on the aquarium are difficult to see in the photograph, so I will upload a dated chart which shows how long the cycle took, which days the water was checked, which days it wasn't checked, and why.
Names for plants and fish will also be up soon!

Edit: Any other recommendations for fish? I'd like to get away from the standard types you find in big box pet stores.
