Looking good i love juwel marine tanks . Looking good what pumps u got running? in my 240 ive got a 50x turnover lol but 2 used to blow the water surface so they cant count as much but still. Yer put all ur lR and start aquascaping make it looks good while its cycling.
Looking like a good start! Just a quick note, you wont be able to have a Yellow tang in there. It will be way to small, and even more so when your 20kgss of LR come.
