Marine salt water fish...
 

I purchased a 60 tank for marine salt water fish, already have a 105 litre tropical tank for 6 months (which unfortunately I am having problems with losing fish now), however, I just wondered in easy steps which I can follow on easy set up as I am new to all of this, but really enjoying the experience even though i am having troubles with my tropical tank right now. The 60 tank has the lighting, and internal filter and stones, that's it so far. Thank you.
