Cyanobacteria in the brackish shrimp tank

**Rob in Puyallup** · 01-22-2013, 07:00 AM

Lol! Link is opening to something called Ultra life Reef Blue Green algae remover.

Do see in that link the name of Mardel. Will find my way to it.

I bought some API Erythromycin Saturday, basically the same product.

I've read conflicting data on the safety of antibiotics such as this when used with live rock.

the only true non chemical way to actively kill cyano that i know of is UVC, as in a germicidal bulb(since uv sterilizer wont actually shine on it). other than that, its the usual methods of decreasing light, trying to eliminate phosphates, raising nitrates(but i dont think that will work in your case...), etc.
it wouldnt fix the underlying issue though...

removing it physically helps. if it is running on a low amount of nutrients, removing it keeps whatever is locked up in it out of the column.

im not sure how antibiotics will affect the live rock. it would worry me, but i have never tried it, so i cant say if there is any danger.

Maracyn-Two is safe. It's a product I've used myself - both fresh and marine versions - with invertebrates.

Erythromycin is OK for shrimps. I test it with Neos, CRS, tigers. I don't know how TB's will be. Cardinal Sulawesi has been wiped out on second day -at least on me.

One of the sources of my concern:

somewhatshocked · 01-22-2013, 02:59 PM

Maracyn-Two will not harm the beneficial bacteria within your tank.

**Rob in Puyallup** · 01-22-2013, 03:02 PM

Working in that direction, Jake.

Seems API EM erythromycin is the same med, isn't it? I have some of that.

somewhatshocked · 01-22-2013, 03:38 PM

No, not the same.

Maracyn-Two is Minocycline.

somewhatshocked · 01-23-2013, 11:18 PM

End up trying anything to eradicate it?

**Rob in Puyallup** · 01-23-2013, 11:35 PM

I returned the erythromycin and got the Maracyn 2 on my way to work last night. Will throw some in the tank tonight.

Carefully.

I could only find the freshwater version. I've read that to use it in salt water it takes twice the dose: 20 mg per 10 gallons vs 10 mg per 10 gallon.

I think I need to wake up.

Okay... I've added the recommended 10 gallon freshwater dose, two packets.

Fingers crossed!

Just added the second dose. No obvious difference to the cyanobacteria at this point.

somewhatshocked · 01-25-2013, 02:06 AM

Hopefully it'll do the trick after the five day course.

Usually does the trick for me in freshwater.
