Hello salty people!
I'm a long-term freshie (and have no intention of changing!); my 14 year old son, however, has fallen for marine tanks in a big way. He's been looking after a shoal of tiger barbs and some zebra loach for a year and is well acquainted with all the 'normal' fish-keeping skills of water changing and the nitrogen cycle etc.
Now, I have an empty 48x15x18 tank that I've been thinking about setting up as a tank for some angels (freshwater angels, lol) and my son is casting longing eyes in its direction
I've tried to get him to go with a FOWLR system, as that seems to be the easiest, but no; he wants corals and is not interested in having any fish at all
So, what kind of equipment would we need (bearing in mind I'm on a fairly limited budget)? Would just lights and powerheads be enough, or do we need to run some kind of phosphate remover or other chemical filtration (we have an external filter we could use for that)?
Also; do you have to add all the live rock at once, or can you build it up over a few weeks?
