Hi Guys,

I am 2 and a bit weeks into the cycle of my tank...

tank is 450L with a 100l sump, with a Reeftek TS2 and DSB.

temperature is constant at just under 25 deg, trying to get this up to 2 exactly.

i am running 2 x T5's for about 10 hrs a day, and run a light in the sump at night.

I have about 60kg "live" bio rock from someone els's system, and about 15kg of live rock, (mix of kenyan, figi and Mal).... plan to up the live rock KG as the budget allows.

At the moment the tank does not have any sustrate although i will be adding reggies play sand when i get a chance later this week, but this will be for asthetics alone !

so after all that, the question....

last night i noticed what appears to be dark brownish green spots of algea, between 5 and 8mm in diameter.... mostly on the glass bottom, and on a few of the rocks? Is this cyano bacteria? is this a normal part of the cycle? is this good or bad?
