Problem algae

[Donmarco]

I'm having some problems with algae in my tank (photos attached). The phosphates test at .16 ppm, ammonia, nitrates and nitrates at 0. I also have a biodenitrator and phosphate reactor in the sump. Last week I changed the reactor media.

 

Any ideas?

They could all be that low because the algae is feeding on it making it that low.

What's the age of the setup

The tank setup is 7 years old. I did have an equipment malfunction in early May and lost all my corals and most of the fish. I cleaned everything up and maintained the tank for almost 3 months before beginning to restock - added 5 small fish and then, a couple of weeks later, 3 small coral frags. The algae appeared before restocking began.

 

You suggested that the algae could be feeding on the phosphates, giving me a false read. How do I obtain an accurate read?

There really is no way I know to get the pre consumption reading. You said you had equipment malfunction? What was this malfunction.

Also some of the equipment may be accumulating junk if not regularly cleaned and aiding nutrients

Use cheato to out compete the pest algae

Use phosphate remover and carbon.
