Following the crazy frozen weather in Texas I lost my entire freshwater system. We had been talking about moving to saltwater but we weren't ready for two tanks and making lemonade out of lemons we moved to saltwater. To get started, we used what we had. We are currently using a API cannister for filtration and some Discovery Channel LED lights (FOWLR tank until we buy new lights). We purchased Caribsea live rock and integrated some natural limestone. We have the Caribsea Hawaiian black sand and have almost finished our cycle. We followed the brstv 5 minute guide on how to cycle and have two teeny tiny clownfish "Sushi and Mochi" eventually we will upgrade a whole slew of things but this is our start!
