Default Maracyn (erythromycin) and Blue-Green Algae

Maracyn Update: Today is day 5.

I've been dosing with 1-200 mg tablet daily. I expected to see the B-G
algae "flaking" off, but that doesn't seem to be happening unless the fish
are gobbling it all up (unlikely). But at least half the mass of

nastiness
has somehow disappeared. There are still strongholds and redoubts in

amongst
the shadows of the plants and rocks, particularly webbed between the

strands
of monofilament where I have riccia tied to stones.

The tank is an unfiltered 20-gallon long with a water pump and CO2

injector
embedded under the gravel in the center of the tank, and 55-watt compact
fluorescent lighting. It's planted primarily with sag. subulata and

riccia,
and is inhabited by two botias, six zebra danios, and the seven largest
tiger barbs in all christendom.

Because there is no filter, the tank has become very cloudy with some very
funky "swirling mists" effects around the water pump. I did a 50% water
change yesterday which cleared things up for a few hours. I tried to put

a
few red ramshorn snails in to blitz the B-G but, as usual, the botias had
eaten them before I'd even left the room. I planted some hygro. corymbosa

I
had pruned out of another tank but, as usual, the botias had dug them out
and they were floating at the top of the tank before I'd even left the

room.
Perhaps the botias are my REAL problem.

So, all in all, I'm disappointed that things aren't moving along faster

but
also hopeful as some improvement is visible.

Hi, Robin. I just started using it in my 20-gallon yesterday, so if you

can
wait a few days, I'll let you know how it went. I'm using 1

tablet@200mg/20
gallon, or half the recommended dosage.

Hello Everyone:

I have read the details posted at the Krib regarding the use of

erythromycin
to eradicate B-G Algae. There are differing opinions regarding the

dose
required to do the job. Some say use the dosage as per the Maracyn

package
while others suggest one half the recommended dose. The Maracyn

package
I
bought recommends 1 tablet(200mg)/10gallons of water to treat "Body

Fungus"
infections.

Has anyone on the list used Maracyn to eliminate B-G Algae and if so

what
dosage did you use?

Thanks in advance.

Robin P.






I have just completed treating the b/g algae in my daughter's 10 gallon with
Maracyn. The B/G algae looks like it's entirely gone, and there are minute
white flecks lingering which I suspect might be dead b/g algae - as you say,
it seems to have otherwise disappeared.

I got the swirling cloudy stuff as well - I figured it was a bacteria
bloom. I tested the water - ammonia and nitrites at 0. Today, I did a 50%
water change and added some carbon to the filter to remove the remainder of
the maracyn.. Later on I tested the water - Ammonia 0.12 ppm, nitrites 0,
nitrates at around 3ppm. I expected there to be some die-iff of the bio
filter, and additional ammonia from dying b/g algae, so I'm not too worried
about the elevated ammonia yet. We'll see if it settles back to zero after a
couple of days. Meanwhile I added a bunch of limnophila, which will
hopefully soak up nutrients so as to prevent the b/g algae from returning.
I'll keep you posted.
