    Wondering how easy it would be to convert an established freshwater aquarium to saltwater. Would any of the bacteria survive?

    Everything has to be gutted and sanitized (tapwater and distilled white vinegar). Freshwater bacteria don't survive in saltwater and that's not how the biofilter works in a saltwater tank anyways (Biofilter is held in the rockwork aka live rock as opposed to filter media).

    There are more differences than similarities with saltwater and there are a number of bad habits you will need to unlearn from freshwater when switching over.

    I'm just trying to venture into the other side of the hobby. I've got 6 freshwater tanks at the moment and just looking to do something simple like a couple clownfish.

    Don't fall for it. They offer cookies. Looks like chocolate chip but there raisin. Ok. Forget everything you know about freshwater. Other then a cycle they are totally different creatures. Once you pass low brackish its a whole new world. Freshwater only teaches us bad habits.

    As mentioned by David, I would strongly encourage you to spend a while researching first as it will teach you far more than any freshwater experience. Saltwater isn't necessarily hard (especially just for a couple of clowns) but it is good to take your time to learn how things are different between salt and fresh. RODI water vs treated Tapwater, use of a refractometer, How Evaporation is a bigger factor with saltwater since water evaporates but salt doesn't, API is generally inadequate for salt water testing, the differences between things like Live Rock, Dry Rock and Carribsea Life Rock and the Pros and Cons of each, Differences between Bubblers/Air Stones and Powerheads/Wavemakers, Frequency of Water and Filter Changes, Established Filter Media vs Established Live Rock, Can't pack saltwater fish in like freshwater fish.

    Just started
    Clean the tank add live sand between 10-20lbs and live rock around 15lb wether you want to start with live or base. then how do you get your saltwater such a small tank a lot Just choose to buy it from lfs with a tank this size around $1 a gallon with around 4-5 gallon weekly change then get a descent hob a heater and some wave makers with your desired flow. Put it all together and cycle it. You still got lights and maintenance Stuff test kits lighting etc but this will put you in the ballpark.

    Do some reading up on it first. There is a TON of literature out there on salt water aquariums. 80% of it is opinion and useless ****. Depending on what freshwater fish you keep, saltwater is really not diffrent. Some slight chemistry diffrences and potential learning curve with corals. In the grand scheme of things it is just a chemistry equation just like freshwater.
