Cyano battle with GFO?

[Master Kyle 297]

I have been battling cyano on some parts of my rocks which I believe was due to high phosphates about 2ppm. My sandbed is clean from my cleanup crew members and the tank is over 2 years old. My nitrates are zero and my skimmer is working well so I don't think it is a nitrates or dissolved organics issue. I upgraded the flow in the tank and that has reduced the overall amount but it is still present. I have 300 gallon reef and water changes every 2 weeks isn't practical for me so I decided to add a GFO reactor two days ago and I have covered the tank to do three days of darkness to hit the cyano from different angles. Has anyone had experience with using GFO to get rid of cyano? I'm hoping the GFO and 3 days of darkness does the trick. I have also cut back on feeding a lot. I feed the fish a frozen mysis or brine shrimp cube 2-3 times a week with feeding nori and pellets twice a week and was wondering if that is good for less nutrient importation in the tank? Also should I run carbon on the system enough though I have a skimmer?

cyano is usually knocked out by increasing flow. more pumps, you can set one to blast directly where you are getting cyano. As last resort I'd use red slime remover - it is reef safe.

here is a video on it..

gfo removes phosphate. Cyano is not related that much to phosphate, but to LIGHT quality and good skimming. Turn the lights out for 3 days, and acclimate them back up again. Do this once monthly.

I currently have 2 Jebao wavemakers on each side of the tank. I seem to get a lot of flow almost as if it was setup for an SPS tank. My LPS and soft corals seem happy except for the zoa colony that has some cyano growing on it. Surprisingly I forgot to mention I was given a small adult koran angel as a gift and it have eaten a considerable amount of cyano on the rocks but it's such a big tank it can't eat it all. Have had the tank covered for almost 2 days now but I don't want to rush and turn the lights back on. I want to make sure it is all gone for another 24 hours. If it comes back I will consider a chemical treatment but is there one that won't make the skimmer go crazy?

I normally have my LEDs at 50% power for both whites and actinics for 8 hours a day

i was fighting a losing battle. That was until i adopted some of these methods.

I had an outbreak when my tank was new (2 or 3 months old). I used chemiclean and haven't seen any signs of it since (5 months).

Follow the directions exactly and you wont have a problem.

Research and you will find lots of info.

Hey guys I actually finally solved my issue with cyano! What I did was run my refugium lights for 18 hours a day on the calerupa and increase the flow in my tank. I then took a turkey baster and blasted all the rocks and the skimmer skimmed out all the organics and now I have no issues! I think having a GFO reactor helps as well but I can only using about half the recommend amount
