Need help with ID

[Memoreefs]

This is new tank that's about 4 months old now. I am new to reef and I have been battling this thing for over a month with no luck. I did a 3 day black out with hydrogen peroxide dosing, tried chemiclean.

I think it's dino but not sure.
Please someone help!

It is dinos, all tanks get them and yes they will go away on their own as long as you have good water parameters.

But my corals are getting covers and many have died.
Anything i can do to prevent corals from dying?

Well,
the biggest drawback with reefing is that we all want to put a lot of corals on the rock work before it is really time. Then when the dinos come they choke and kill them.
I know I will catch heat for this but there is a product that will knock dinos out really quickly called Vibrant.
I personally love this stuff and always had it around when I was freshly cycling all of the tanks that I set up.
There are other methods that work but the key is patience before adding corals to your rock work.
Hope this helps.

And i shouldn't do water changes right?

Well,
I forgot to ask what your parameters are first...
