OK - thanks for all the replies. Made some good progress and thought Id update:
Filled the tank with RO
water (living in China means I get 5gallons of RO
water for $1.50 delivered straight to my door and they even help me get it all in the tank!). Then added the salt mix, turned on the heater and let sit for the night.
Bought some live rock (70lb) and base rock (70lb) from my LFS
(I paid for double that and I dont think the delivery boy expected me to get the scales out. I have yet to return to my LFS
but will be soon for a big row no doubt (there are definite disadvantages to living in Shanghai - that all shopkeepers think it is fine to rip off westerners is chief amongst them). Also got 100lb of live sand.
Added it all the next day and the tank has been running ok since then. Water's clear, surface agitation from the return pump is good sump is, after a load of messing about, almost silent. Am feeling pretty happy about it all.
One thing I am a bit worried about is that the tank doesnt seem to be following a standard cycle. I have attached my tank log and I know it is early days but does this look ok to you guys? The rock came from a huge tank at my LFS
and is clearly alive but I am getting readings that would suggest a tank a lot older than 4 days... (ie Nitrite and Amonia dropped to zero and 15-20 on the nitrates..)
Would be interested in your thoughts - even if they are for me to be patient (easier said than done - surely you all remember your first ever tank. Is a really interesting process and I just want to know everything that's going on. My wife thinks I am a weirdo - spending hours staring at a 'load of stones')
