Hi there

Years ago I obtained a 36 gallon long aquarium second hand that I used for several years with African cichlids. The fish have not been in there for several years and the tank has remained derelict in my basement. Is is possible to clean out the old tank to be reused as a terrarium for my toads. If so how would I go about cleaning the tank. I also wanted to know if the gravel could also be cleaned and reused as a drainage layer if I plan on planting plants within the tank



Thanks
