Cyanobacteria in the brackish shrimp tank

**Rob in Puyallup** · 01-31-2013, 02:31 AM

Now not entirely sure that all of the cyanobacteria went away with the Maracyn 2 treatment. Have had the HOT filter running full blast for two days, the water still a bit cloudy, nothing like it was, though. The Opae Ula still swimming, not hiding like I expected.

Not really pleased with the new cyano growth...

Yup, the cyano is coming back with a vengeance, even with the reduced lighting, the increased water movement and the Maracyn 2.

Found on another thread, http://www.plantedtank.net/forums/sh...d.php?t=232338 , that according to the "Redfield Ratio", http://buddendo.home.xs4all.nl/aquar...dfield_eng.htm , the cause of cyanobacteria is combination of nitrates and phosphates. They're out of the correct balance.

In my tank Nitrates measured 0 and Phosphates the same.

I'd post a picture of the increased nastiness but I've reached my photo max...

I think you will have more success with Maracyn 1 or the other stuff I discussed earlier. I am not entirely sure but I think that Cyano is a bit more susceptible to Maracyn 1. Granted I would wait a while because you have probably been stressing the shrimp out.

Gonna try Maracyn tomorrow. Erythromycin. Maybe. If I can drum up the courage!

Just turn off the filter when you dose it and let the Maracyn sink to the bottom. After it all dissolved then turn the filter on. That way there is no way for you filter to get a concentrated dose.

Ugly red carpet.

**Rob in Puyallup** · 02-03-2013, 05:02 PM

Yup. It's moved onto some of the live rock as well. Is why I want to get rid of it

**Rob in Puyallup** · 02-04-2013, 11:58 PM

Today. Delaying the erythromycin.

**plamski** · 02-05-2013, 12:03 AM

I saw result after 4th-5th day in my freshwater tank.

KenP · 02-09-2013, 07:29 PM

Rob any updates on removing the Cyanobacteria.

**Rob in Puyallup** · 02-09-2013, 08:14 PM

Hi Ken,

For the time being I'm trying a more natural route, adding a bacteria supplement hoping it'll out compete the cyanobacteria. I'm still being a bit of an over protective dad to my kids, I'm afraid, and would rather not subject them to antibiotics unless nothing else works.

hydrophyte · 02-09-2013, 08:26 PM

Have you tried dosing nitrates? If there are some plants in the tank to use the nitrates this can knock down cyanobacteria.

Pugman · 02-11-2013, 04:13 PM

I know this is a little late but "Chemi-Clean" works every time. It will disappear overnight. I've been using it for nearly 20 years.

pugman, is that safe with inverts?
