Cyano Driving Me Crazy

[MarkoD]

Ok so id say now 70% of everything that is touched by light in my tank is covered in cyano. rock, glass, sand.

Over the past 2 weeks its gotten worse and worse.

I've been using Cyano Starver everyday for the past 6-7 days. skimmer is pulling like crazy.

I have increased flow in my refugium.

I have changed carbon

I have done a partial waterchange

I stopped using Kalk

I changed DI resin

i have all powerheads including MP40 running on full blast (i also stop them and restart them few times a day to create a huge surge that seems to blow a bunch of stuff everywhere)

I dosed Magnesium and alk because both were a little low.

Phosphates and nitrates are still testing 0

Even with all of this im still noticing coral growth and all polyps are extended (my torch coral actually started splitting for the first time and i've had it 10 months)


Nothing is helping!!!! what else can i do?
