Thanks. The other 3gal started as just a piece of manzanita. Now it's a moss jungle. This one will grow out over the course of a few weeks. Fissidens should bush up pretty nicely and the Xmas Moss from Han is super-healthy and should grow quickly.
pH with RO and this substrate is pretty low. So it takes a good 3-4 weeks to be safe. I almost always run things longer to develop a nice environment for shrimp. The more goodies growing on surfaces, the better.
New tank is already processing half a milliliter of 10% ammonia per day. Since the cycle isn't going to take long, I'm excited. Means I'll be able to grow all kinds of goodies in the tank over the next month or so.
