I can’t seem to get rid of cyan bacteria ahhhahahahahhhh

[carlos413]

I am using R.O. water, no phosphates or nitrates. It’s only on the sand bed but it looks awful. I am feeding once a day. The lights are on a timer for 10 hours each day. I have a HOB refugeum 4 gallon with some micro algae. The lights on the fuge are on opposite of DT. My ph is at 8.2 temp 78 ammonia zero and zero on the trates. I did have a hair algae problem in the past, switching from tap to RO water maid a huge difference. I did use a powder my lfs recommended it worked temporarily but the stuff came back. I do weekly water changes of 12 gallons. Is there anything else I can do to get rid of this cancer alga? Any other info I can provide to help with this problem? Oh I forgot my tank is a 55 gallon and I am using pc lights. My stock list is two clowns, one royal gamma, a purple fire fish and a green mandarin.

What are you feeding????
You can try lessening the light time to 8 hours also...do you siphon the cyano out?

How old (new) is your set up? Is the refugium your only filtration?

No, I scoop it up with a plastic spoon.

 

[mantisman51]

Your set up may be lacking in the filtration. I don't know for sure, but it seems like there should be some more water filtration to remove the organics in the water. FWIW, I had cyano for the first 3-4 months after I set my 125 gal up as SW.

I don't think that's a very good idea....you need to remove it ...not spread it
Would you have a full tank shot?
I am wondering how much flow you have .... how many powerheads??

BTW, PR is the bomb! I love Culebra and the area between Cabo Rojo and Ponce. Absolutely gorgeous.

I had a HOB filter but had to take it down because I could not fit the skimmer and feuge. I had the problem when I had the filter and skimmer installed.
I also have two Koralia 2 and a penguin 300 gph power heads.

 

[meowzer]

Are there any dead spots???? (That the Powerheads are not moving?)
Full tank shot!!! please??

3 power heads 300 gph each

 

[meowzer]

Do any of those powerheads move the bottom??? You may need some flow on the sand...NOT moving the sand exactly....just blowing over it.. you may be having too much nutrients settling.
what is your clean up crew (CUC)? And what are you feeding?

I have eight nasarus snails, eight turbos, two emerald crabs. Two red legs hermits. I have some beneficial hitch hikers’ slugs and starfish.
I feed a combination of mysis, brine with spirulena, chopped krill. I get some flake food mix in there for variety. I had been feeding two times a day down to one time a day. I got my lights down to 8 hours from 10.

how old are your bulbs?
cyano bacteria is an excess of nutrients in your water...
yes, it is a bacteria, not an algae. this means that it will spread more with warmer temps as any bacteria. so if yoru tank gets any high temp swings, expect to see a little more than last time.
have you tried good size water change?
i would take a net and get out as much as you can to try and stop if from spreading.
check your RO water for a double check.. it is ro, but the membrane in the unit could of been bad. resulting in nothing more but filtered water. (no nutrients removed..)
if this water is from a lfs, see if they knwo anyone else having problems using it. if its yours... welll im not sure what to say. lol

 

[bill109]

i see you feed 2x a day. down to 1x a day. i feed every other day.

has anyone heard of chemiclean? my lfs has told me they have had good luck with it. one thing is though figuring out what your actual number of gallons being you have to take off for live rock and sand but add for filtration. anyone have any advice on this?

Chemicals are not a solution just a bandaid, The problem needs to be fixed.
