Setting up my 150 gallon tank....question re: cycling and is my tank 'ready'

[newreefer_59]

Had my tank running (live rock with bacterboost initially) since Dec 1. It is a 150 gallon setup and just wondering....at waht point do I know it has definitively cucled (ie: ready for fish, etc). Still having a bit of an algae bloom as it is tough to get rid of it all at once, but have started using RO-DI water in my WC's. I have a few pieces of coral that seem to be doing ok - they are in my profile simmary. So, what tests that I run tell me it is ready to introduce a fish or two?

many thanks
