10 gallon salt tanks are for more experienced reefers. If you do a water change and your new water is not perfect. you have almost no buffer water to stabilize or help dilute mistakes. If you do want to go through with it. I recommend 25 lbs live rock, a 55 watt 50/50 PC
. since its only 10g you should purchase your life rock and live sand. (use the calculator for depth) through it in the tank and let it sit for a month to cycle with the lights off. (weekly taking out the rocks and scrubbing off any dead Organic compounds.) As far as everything else I recommend just browsing the forums. You prob will only be able to keep 1 fish in there.
Nitrogen cycle test kit
and maybe live sand.
Powerhead for water agitation
Lots of extra buckets to mix and store water.
