Red cyno bacterias

[Seasidenj]

So bought some corals and wound up getting cyno after not having it since tank new for 2 years.Now can get rid of it.Should I start all over cause this crap is driving me crazy

cyano bacteria is easy to remove with chemiclean. If the cyano is awful do two rounds of it. Its reef and invert safe so you should be all good

Cyano is a challenging problem. Antibiotic treatments like Chemiclean often kill it, but it often just comes back. Manual removal is often a good plan as it exports the nutrients in it, unlike killing it. More flow often reduces cyano as well.

can you post a picture of it. Cyano usually needs a fuel source. I had a horrible case of cyano in my tank for around 6 months. does you tank have sand? sometimes a deep clean is the only way to go. no need to start over.

worked on multiple tanks 2-3 rounds of chemiclean eradicates it for good I would say 95% of the time. manual removal is a pain imo

If I understand correctly, you recently added new coral to a reef tank that already had coral and fish (?) and after X number of days, the cyanobacteria began to grow on the new coral plugs (?) and spread to the rest of the aquarium.

In the last several months, have you started dosing coral food or changed fish food?

does changing food cause a cyno problem.ive been having a problem with my tank for like 3 months

At this point in our research into cyanobacteria mat formation, the local accumulation of organic matter is our leading suspect for the growth of cyanobacteria. Unfortunately, detecting or predicting where accumulation occurs is not yet possible unless it is so heavy you can see it.

Is it the food? Maybe, if it sinks faster or you inadvertently started to add more when you switched brands. I tend to think that the cyanobacteria was likely going to grow because of organic matter accumulation no matter what you fed it.

There is a popular narrative about nutrient levels, that when nitrate and phosphate levels are low, nuisance organisms tend to grow. Maybe bacteria that ordinarily keep organic matter accumulation in check don’t do their job when nitrogen starved.

This is a very complicated issue, one that you will have to patiently feel your way through.
