Bad cyano
 

After buying a few new corals my tank got cyano outbreak right away. It started as being on sand bed only to rocks on sand now n kinda covering some corals. How I get rid of it? I've been vacuuming my sand of nasty
Gunk during water changes now.

Chemiclean works really good. Just follow directions and it works just like they claim.

Can it be harmful to fish n corals? Will just water changes work?

I use it whenever I have cyano and it works great. My sps don't seem to mind at all. I know many people who also use it in a mixed reef. I have also had success fighting algae by doing very large water changes every day for about 4-5 days. And I'm talking like 80%+. Thats just my personal experiences though.

You could try the KZ cyanoclean. It seems to take 6 to 8 weeks to work but no need for oxygenation or water changes or crazy skimmer foaming.

Your lucky, thats not bad at all. I had cyano so bad(negligence) it was about 1/4" thick everywhere. I dosed chemiclean once a week for about 6 weeks and started using kz cyanoclean along with kz coral snow about 5 weeks in. It was a long road back to a clean tank but I am just seeing the last of it now. One thing I did add that seemed to help was I dosed a vial of Prodibio reef booster. Could of been coincidence. This was all done while doing twice a week water changes. Once after the chemiclean treatment and another a few days later. It was about 20-30% each time. There were other little things I added as well, sand cleaners. About 2 dozen nassarius snails both big and small. Changed my filter media(canister). I had to hit it hard and by the looks of it you wont have to go to that extent. This all took me about 3 months. Follow the instructions to the letter when it comes to chemiclean and you will be fine. Cyanoclean is a different animal as it is bacteria that out competes the cyano bacteria. Kz recommends complementing it with kz coral snow. dont know if it helped but the tank is looking waaaay better. Good luck

Another vote for ChemiClean. It just works. I've used it twice and haven't seen any adverse affects to either corals nor fish.

I've read its a killer on brittle stars and hard on pods. I wanted to try it on my tank, but was nervous for my Mandarine if it took out my pod population. Is this a myth?

That would not be good then since I have a mandarin that only eats pods. My cyano seems to stop going nuts not after a decent water change n lots of sand vacuuming

I have a bajillion pods. Chemiclean didn't seem to do anything to them in my tank.

Here are a few things to look at first.
1 how much flow - you might need to increase the flow or point a power head toward the sand.
2. what is your po4 and no3? - you might have a nutrient issue. Tap water? if so what is your TDS. Doing water changes could be adding to the issue.
3. what type of lighting? what is your photo period? Might have to change bulbs or eliminate the red spectrum.
4. Quick fix and works fantastic redcyano rx - but will come back if other points are not taken care of. It is common for setups that have been up a year or less.
5. cyano loves low PH
6. how much are you feeding?

The plate coral does not look good - IMO i would dip it (brown jelly) and place in a high flow area.

chemiclean. Just works. If the cyano comes back, then figure out why. If not, you're done. I've used it the two times I've had cyano outbreaks over the years, and nothing bad happened.

Chemiclean used here...works great. Never had it come back.

Cyano pretty much all gone now=) no chem needed. Just a 20g water change for my. 75g tank.

check out your salt, it maybe a bad batch. I used to get cyano with H2O and after switching to Reefchem reef salt I never have any problem
