| Re: Anselth's 70 Gallon Tech Tank upgrade Barb, sorry I missed your question! The sand is about 3" deep. It's deeper than what I had in the 50, and I like the change. Between the Sea Hare, Nassarius snails, and the Cucumber, I think it will be kept well stirred, although apparently we're getting a bloom of cyano along the sandbed. Shale said she's going to adjust the flow a bit more to the front to see if that helps. |
