Cyano Problem - Close to giving up

CanayYella · Aug 8, 2019

Hi

I posted some on another forum about my cyano issue and I am sorely running out of ideas and getting to a point of giving up on the fight.

My tank is a 6ft by 2ft tank running two GR 30 G3 Pros and one Gr30 G4 Pro running the triton method and has been running for nearly 3 years. ‘I have run a marine tank for nearly 8 years.

Phosphates 0.04

Nitrates 5 (has been as low as 0 and as high as 20 when trying to solve this).

KH 8

PH between 8 and 8.3

Dosing Triton.

Running Rowaphos

RO water running at about 0ppmI

Started running Siporax 6 weeks go as removed the Nopox. (Started dosing Nopox to try and lower Nitrate to stop the Cyano)

I have tried

1. Changing water every two weeks (not supposed to under Triton)

2. Increasing flow (3 MP40s running)

3. Filtering water through filter sock.

4. I have removed red from the light spectrum

5. Reducing nitrates to close to 0 by dosing Nopox since removed Nopox hence Nitrates back to between 5 and 10

6. I have tried the “miracle cures” “chemiclean” (made no impact)

7. Raised KH

8. Blast with turkey baster

Anyone else got any help or suggestions I could try.

People have suggested a constitution test or buying a microscope. Happy to do so if it would give me a clue as to what else to try.

Have you tried using it against itself as a nutrient sink? Reduce feeding and siphon it directly out of the tank each day, eventually whatever it's feeding on is bound to be used up. Last time I had a stubborn patch of it, I used some 3/8 vinyl hose and sucked it all out as well as an 8" round patch of sand where it tended to grow.

to my knowledge cyano forms when nutrients are low, so stopping the nopox was a good idea... although 5/.04 aren't really low...chemiclean has always worked for me, but you have to have good oxidation...

I agree to continue with manual removal, discontinue the nopox (that and vibrant are known for cyano aftermaths), hopefully you can catch up to it without the use of chemicals

I used refresh from Dr TIM and it nocked mine out. Greatly reduced it in my fowlr tank as well. At one point in that tank the rocks and walls where all red. That one was a nutrient rick tank too

23 pages where sand bed causes your issue:

Official Sand Rinse and Tank Transfer thread

If you are reading this thread to cure a tank invasion from a link I sent you, we do not need to identify your type of invasion here we do not need you to test anything at anytime regarding nitrate, phosphate etc Above all, we do not need to see a microscope slide picture of your invasion at...

www.reef2reef.com

we should evaluate the role your sand, whats in between the grains, is playing if any

its neat you didn't list it in trial. Its the single most likely cause.

There's always my R2R highly acclaimed PLAN B

PLAN A is to get in the habit of BLOWING OFF your LR every other day with a strong 1200gph powerhead to loosen up the junk that hopefully gets skimmed out.

A turkeybaster just doesn't penetrate the LR enough

Sometimes LR just doesnt give up the absorbed organics easily. You gotta use some p o w e r

how many rounds of chemiclean did you do?

double

If no shrimp in the tank, try dosing 1ml of 3% hydrogen peroxide per 10gal of water every 12hrs. It takes about a week but I got rid of cyano in 2 tanks (one unintentionally). You can safely increase the dose to 3-5ml. Shrimp don’t do well unfortunately.

I fought cyano for nearly six months, doing weekly water changes and tank cleaning only to see it pop back up over night. Always had 0 nitrate and 0 phosphate. Finally bought a algae turf scrubber and BAM, no more cyano. I've since changed to chaeto in my sump with same results. I get a small spot of it every now and then, only when I make some kind of change to the tank. I think it has a lot to do with an imbalance in the tank. I stopped using the ATS only because I couldn't stand the smell when I was cleaning it, so that's why I switched to chaeto.
