CRS for Fluval Spec
The tank is a low tech setup and I want to keep it that way since its at work and I can spend too much time on it. I'm doing 30% water changes weekly so I'm hoping that will be good enough to keep things clean enough. Should I be doing water changes twice a week? I'm also dosing a 1/4 ML of excel about 3 time a week. I've read horror stories about excel and shrimp, but I think that's a low enough dose for a 2 1/2 gallon. I want the plants to fill in a bit more.
