I'm not using Dr.tims method on my tank. I'm using the cycling method here. I plan to cycle it by using water from my main tank when I do a water change and a cycled sponge filter.Not quite following all your threads, Rocky. Been super busy. How are you going to cycle the new betta tank? I tried the Dr. Tim‘s methods you’re using on one tank & absolutely hated it. Before & after that aborted attempt, I‘ve gone with filters cycled in an established tank. Have two big Fluval AC 110s cycling in two tanks now, waiting for the 125 G to arrive. Been >3 weeks & ETA of new tank unknown. They say there’s a big nationwide glass shortage.
