Need advice on salt and substrate

[spit.fire]

Coarse gravel, thin layer. Don't buy the live stuff, its a rip off


As far as salt goes it depends on a lot of factors ;
What kind of corals you want to keep
How often are you going to do water changes (not how often you plan to)
Are you willing to dose
What size of tank and what kind of budget do you have
Are you premixing the day or week before or mixing before you do the water change (I don't reccomend this)
