So i have started getting cyano bloom in my aquarium from last month or so.. the aquarium is 10 months old... i initially thought it is because the tank is maturing.. but its been there for over a month.. i syphon out the red algae regularly.. been diligent with the water changes.. dont feed too much at a time... i also increased the flow by adding a mp10 in my 34 gallon tank... nothing is seem to be working... do I just need to be more patient and continue doing these things? i dont want to go via the chemical route..
 
Get some Chemi clean it works great make sure to read the directions and run a air stone to put oxygen into tank.
 
I have chemi clean.. havent used it yet.. i heard although it is safe for fish, corals and invertebrates it kills the useful bacteria as well... thats my last option if everything else fails..
 
10 months is still a fairly new tank and is still going thru changes. I would keep at siphoning it and water changes. Are you using RO(DI) for your water? What do you have for livestock in the tank and what and how much do you feed?
 
i use rodi.. and the TDS meter is still showing 0 for output.. i have 2 green chromis, 1 royal gramma and 1 six line.. i usually feed a pea sized chunk of larry's reef food.. i thaw it, strain the water out and then put it inside the aquarium
 
I would just do water change every day for the next 10 days. just do around 1g -1.5g each time and just siphon out the skunk.
If you do that, they will not be able to keep up with that pace and will eventually die out
 
Do you have a skimmer on this system?
 
Aren't there cyano eating snails?

Look at reef cleaners. I believe I saw that in one of the descriptions.
 
It sounds like you have a pretty good process and equipment. I'd say to do frequent WC's like mentioned above and you can also cut the light period. Larry's food is great and really clean so I do t think you're feeding is the problem. As mentioned, tank is still young (I'm in the same boat) so power through this, it should pass
 
I use Dr Tims Waste away. Its all natural, and works great. They have a bunch of different products, but the waste away is what I used for my outbreak.

Good Luck

I'm in the same boat also. New tank- Bought used 3 weeks ago with LR and sand and filter media... mini cycle. All params have been good since about a week after I got it..
But cyano bloom. I'm guessing my water (not ro/di) has phosphates since the bloom started BEFORE adding fish. I added a powerhead, and it seems to be dying off, but it is still in the sand, and ugly. I tried syphoning, but the sand is fine and it picks up more sand than cyano..
 
Honestly,the only thing I've ever seen a powerhead do to cyano (once it's formed)is roll it neatly on the sand bed.
I think the reason most people mention PHs is that it helps keep food from settling on the sand bed and causing the cyano outbreak.
I've seen cyano on PHs before and it had no effect in it growing.

I have a few patches of cyano here and there.But,I know what caused it.
I fed some reef chili a few nights and I'm sure some settled here and there and became nitrates to fuel the bloom.
 
The best way to solve food issues is with plenty of serpent and brittle stars. I have two brittle and two serpent stars in a 40b. The fish eat like pigs and the stars finish the rest.
 
Honestly, I'm sure the other methods work--but a long term solution so it doesn't just come back would be get a good balance on your nutrients and keep you system clean (skimmer cup, power heads, etc). That's my view anyway.
