Algae issues in a 'sterile' tank

[synaclef]

Hello everyone.I am having some algae issues in a 7 month old tank and would appreciate your opinion on this.I am seeing small patches of green hair algae on the rocks.
I started the tank 7 months ago using only dead rock.
Parameters are
Ca 420
Alk 8
Mg 1400
No3 5
Po4 0.04

The only life source introduced so far other than fishes are a couple small pieces of live rock(really small)for introducing corralline and a soft coral.Pest introduction was a huge concern.
I took my time on this tank and did not get more corals so I can do blackouts until the tank establishes.

Coming back in the hobby after 10 years I see a lot of debates on how different strains of bacterial populations can play a key role in keeping algae at bay in new tanks.Could it be that I have not introduced enough life into the tank? I have never faced similar algae issues for so long in previous tanks.

Please let me know if you need more information on the tank.

Reef systems are pretty complex ecosystems but to oversimplify it the equilibrium will promote algae or it will promote corals and corals are competing with algae for nutrients. SPonges play a huge role also and along with micrbial stuff htat can't be stuck in a bottle and are the reasons I always use a fair amount of quality maricultured liverock in setting up a system, roughly 1/3 lb to 1/2 lb per gallon. (FWIW most of the pests I've gotten have come from other aquarists, not maricultured live rock and the pest that's killed the most corals and fish are BTAs.) Here's some videos you may find informtaive:

"Coral Reefs in the Microbial Seas" This video compliments Rohwer's book of the same title (Paper back is ~$20, Kindle is ~$10), both deal with the conflicting roles of the different types of DOC in reef ecosystems. While there is overlap bewteen his book and the video both have information not covered by the other and together give a broader view of the complex relationships found in reef ecosystems

Thank you very much for the links,I will go through them.

I do not have access to maricultured live rock right now,what would be the next best thing?

Would adding corals be enough in establishing these conditions?
