Hi guys, I'm really interested in starting a marine tank. However, as I already have 2 2ft FW tanks I have to go with a nano. I was considering getting a dymax iq5 as many people say that's a really good nano. Am thinking if keeping one or two clown fishes as the lfs told me that they are good for beginners due to how hardy they can be. Some have told me that a chiller is a must while others say that a nano tank just requires a fan. Any senior here can guide me along on what to do and how to start this nano tank? for example, how to cycle a marine tank? I know for fresh water the soil I use already contains ammonia but for salt water I'm not sure how to get it started. Really hope some seniors can help me with this project I'm about to start
