Am back at work now so access to site can continue. I've been having leaking problems thru durso into sump in trying to set up my tank (900x300x600) which i've finally sorted. Luckily testing setup with fresh water first before making things permanent. I will be putting the salt water in this week-end and the arragonite in the sump as DSB. I'll also comission the skimmer and gets things curing from there. I'll be inherating a sun coral as my first addition as well as a little kenyan too. For now my lighting is basic (1 white light). Does anyone see any pro's/con's so far. Once time and money allow I'll get more, better lighting in place.
