Corals having trouble with some sort of red bacteria

[gabrielquissak32]

Before I start with the problems I’ll give you guys some information that might be needed
System is 180g
Tank is 4 months old
Stocked with cuc, couple of clowns and one baby bamboo shark, corals.

Filtration with skimmer and filter socks.
Parameters
Alk 8dkh
Ph 8.2
Nitrate 25
Calc 440
Mag 1500
Phos 0.02
WC 10% weekly . Been a bit lazy last couple weeks so it was one in 14 days.

Have noticed this red thing growing around some of my corals, goni, dalas colony, toadstool and bubble.
I can almost peel it off if I get the coral out of the water but it seems to come back and stick to it.
Any idea what is it and how to deal with it?
Thanks for everyone’s time
Sorry for some of the blue photos

Looks like dinos to me. Get whatever purple non sulfur bacteria you want and dose large amounts for the next week. I like microbe lift special blend, it's cheap and you can get it at the big boxes. It looks like it's only now just starting so you may be lucky. Even if it's cyano the bacteria will help. It's photosynthetic so don't kill your lights but turn your skimmer off.

I do not see anything wrong with your water parameters.

My tank is 8 months old and is kind of stable (in my own terms).

All I can say is before the 6 month mark, all kind of issues happened to my tank and most of the time I could not find their source.

Hang in there, keep the water change routine. Your tank will soon be mature and that is when you will be able to decide if you should prolong the interval of each water change. (hope that makes sense, English is not my first language )

Happy reefing!
