So, my long-awaited Mbuna build (I started messing with this project 5 years ago!) has finally got water in! And rocks! And sand and a Universal Rocks background wall and a light. I retooled the overflow from Durso (thanks to y'all who helped me sort out what my plumbing bits were!) to Herbie, and added a Continuous Automatic Water Change (CAWC) a la fmueller. I got the outflow and the inflow drip running tonight and built myself some rockscape today. And as an added bonus, I got my first 0 ammonia and non-zero nitrite reading on my fishless cycle tonight. :dancing: This is about as cool as things can get without fish. :fish: Here's a FTS, all empty so you can see my shiny new rocks. The tank is a 110 tall, but rotated 90 degrees so it's deep instead of tall. The footprint is 48" x 30".
