Well I've done salt tanks for the past oh 5-6 years. My last cichlid tank was a 125 that I cycles for 2 weeks. My current set up is a 55g with aragonite sand I had in my reef set up 6 months ago. A new wet/dry sump, various rocks that I pulled from the river(cleaned and cycled) and 220w cfl lights. I'm looking to build a nice cichlid tank and don't want to risk killing my first tenants lol
