How old is the tank and what are the parameters. Alk salinity cal nitrate phosphate etc

 

[Adsy541]

Tank is about 4 weeks old
Alk is around 10
Salinaty is 1.026
Cal is 400
Nitrite is 0
Phosphate is also 0

Welcome to the addiction. I saw your three posted threads. Without algae and bacteria, nothing would live in our glass tanks.

You have started up your tank without establishing sufficient competitors and predators (clean up crew) of algae.

Your alga doesn’t look serious to me. Just the new tank uglies for a 4 week mature tank.

Yeah, looks like diatoms. They pop up during a tank's first few weeks and should disappear eventually

Okay is there anything I should it is also turning green

why i have the algae its all over the rock and green film on the glass

So, do you have two different colors: brown on substrate and green film on glass? Did you look at nuisance algae guide link to reef cleaners?

From Reefcleaners link:
Diatoms
Almost sure to appear in a new system, diatoms are some of the most abundant organisms on earth. They usually surface in the aquarium as a brown powdery like substance, within a week or so after a tank finishes its cycle. Diatoms feed on available silicates in your system and will run their course in time. Similarly, because they feed on silicates, anytime you add new sand, rock or something plastic they can pop up.

Manual Removal: Diatoms are easily wiped from the glass with a mag float, a turkey baster or a toothbrush can access other areas of the tank. Be prepared for them to re-establish themselves quickly, they are likely to be able to resettle and have exponential growth rates.

Clean Up Crew: Ceriths, Nerites and Trochus and Astraea snails are effective at removing diatoms, as well as the algae species that usually replace them as the silicates in your system are depleted.



Green Film Algae, Film Algae
filmalgae 300x400
This green powdery film, or cloudiness is caused by a variety of species of microalgae. It is fairly common in tanks of all ages, and tends to be present in some degree at all times. It is only when a bloom occurs that the microalgae becomes so dense as to become noticeable.

Clean Up Crew: Ceriths, Nerites, Astraea spp., most limpets and chitons. Many different species of copepods, amphipods and isopods will feed on film algae as well. Hermit crabs pick at it but are rarely effective against film algae.

@Ads541
Zero nitrate and zero phosphate are not desirable. As a generalization, with low nutrients undesirables thrive and desirables suffer.

The blue coral looks potentially like Devils Hand.

At 4 weeks you should focus on keeping it simple and not worrying about all the different ugly stages you will go through over the next 12 months. You are going to see brown stuff, then green stuff then brown again, maybe some red stuff, then green stringy stuff etc etc.

Just keep temperate and salinity stable stable stable. Feed enough to keep your fish healthy. They will feed the corals for you. Let your biome do its thing.

The corals you've chosen look very nice. Don't beat yourself up if they don't make it through the first weeks and months. Your biome will be going through so many changes and some (maybe many) won't like the change. But it is just a natural thing.
