Hello I am new to this forum I was just wondering what it takes to convert from a freshwater to a saltwater tank I currently have a 100 gallon bow front tank that has 2 Ehim pro 3 canister filters I already have lighting that had actinic lights mixed with regular ones I have chiclids in it right now I only have 2 parrot fish left after a equipment malfunction and was thinking of switching to saltwater and was wondering if I could run canister filters instead of a sump and I was also wondering what other equipment I would need to make the change I am on the lookout for a uv filter and didn't know what else I needed any advice would be great thanks
