New Tank -- Progress

A few days ago I posted the following:

We are in the process of setting up a new marine tank (about 1 week into the
process) -- for the first time.

The tank is 1220 mm long by 350 mm wide by 450mm deep.
We have an Eheim 2217 filter (about 1000 litres per hour) with ceramic rings
and sintered glass substrate, and 1 additional powerhead of 1200 litres per
hour.
Lighting is one flourescent tube 40 watt Powerglo and one 36 watt actinic --
about 50 mm from the surface of the water.
We have an air driven protein skimmer.
We have 28 kg of live rock and about 75 mm of coral sand.
We are targeting SG 1.022, pH 8.1, Temp 26 deg. C.
The NH4, NO2, NO3 seem to be doing as they should so far.

Following the replies I got, I have added another flouro. The tank is now
around 10 days old. We got things going with purchased bacteria, then live
rock, then yesterday more bacteria. Before the second dose of bacteria was
added, we had spikes in NH3/NH4, NO2 and NO3, and then all settled to very
low levels -- after the second dose, only the NO3 has spiked. The protein
skimmer is removing loads of brown "gunk" and we have algae?? (fine hairlike
green mostly) growing on the live rocks and now on the glass.

Based on what I have heard, it all seems to be happening too quickly and
easily -- or am I missing the point? How will I know when the tank will be
ready for fish? Should I clean the algae off the glass or wait for fish to
eat it?

Thanks in advance.
