I am a freshwater person.. but I have been eyeballing a salt set up for a long time, but the startup cost is horrifying. The Fluval Evo is a tank with built in filtration and lighting.. I understand the challenges of a small tank- but is that EVO set up an almost ready to go set up for a basic Saltwater tank? Obviously I would need temp control, but I got that equipment already from previous tanks. If I just wanted some live sand and live rock and once cycled a few inverts.. would that EVO set up be enough. Every time I look into a Saltwater tank I get mixed messages on what is truly needed and what people believe I should have because that's what they have.. as a beginner Saltwater would I be able to set what I described up with a basic set up and minimal costs? Example- my 20 gallon long freshy cost me around 300 total and I love that thing. I just do t want to get in over my head and budget.. like to stay under $200.
