Cyano Driving Me Crazy
 

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?

physically remove it, use filter socks on your drains(if you don't) and change daily, reduce your photo-period, your PO4 and NO3 are zero because the cyano is exporting it, reduce feeding, continue kalk and keep the PH up, alk about 10dkh(raise it slowly)

have you tried chemi clean at all?

+1 on reducing photo period, and reduce feedings if possible

i was wondering if a lawnmower blennie would help that cuz i have a bit of the same problem but in a smaller tank

cyano is actually a bacteria not algae

thanks for the lessons im always trying to learn more

Double post

Before I moved I had bad cyno as well and I got rid of it by decreasing photo period for 3-4 days also reduced feedings and increased my w/c's Also manual removal of cyno during w/c about 1 month later things were starting to look really good. never add chemicals if u don't have to I mean w/c do the same thing

chemicals work but are kind of a band-aid solution.....you need to figure out what the root of the problem is....... what size tank is it?.....how many fish?.....how much live rock?.......what do you feed?..... how often do you feed?.....if you feed a frozen food, do you melt then strain off dirty water or do you add the frozen to the tank?.....How old are your bulbs?.....all these things can be contributing factors.....
