Carbon Dosing (vodka) Vs Cyno outbreak

This is the second time I have tried carbon dosing to lower my po4 levels (0.5). I have been following the regimen in RK magazine but I keep getting Cyno outbreaks. I do run a skimmer (tunze 9005) It has been skimming good dark smelly skimmate so I assumed it was being effective. I have cut my lighting and feeding. The only correlation I can come to is that the dosing is causing the out break. Has anyone heard of this or is my skimmer just not keeping up?
 
I have read to get rid of it you need to stop dosing vodka and add bacteria to the tank. After a week start dosing again.
 
I strongly reccommend Phosphate Control made by blue life. I started using it about a week ago and my PO4 went from .19 to 0!!!! My corals are just popping out with color now and im loving it. Its also reef safe. So instead of the $60 reactor and maintanance with it. A $20 bottle does the same thing, if not better.
 
Not to say that Phosphate Control by blue life doesnt work (I really dont know) but I have used other products that are similar and they just change the PO4 into another form that is undetectable to phosphate tests. Again I have never used that product but I am always skeptical of something that you can just add a couple of drops into a tank and a problem is solved. With products like ROWAphos and other phosphate media you are actually trapping the PO4 in the media and removing it when you take it out. If you dont want to spend the $60 you can make a reactor with a piece of PVC and a small pump.
 
I have restarted dosing vodka and ramped up my vodka dosage fairly quickly. Although I didn't see a bacterial bloom, I did notice a fairly significant diatom bloom... Not sure if this is related or not.

I bought some microbacter7 from BA, and dosed a cap and a half of it yesterday and will cease dosing vodka to see if the diatoms subside. I will continue dosing a cap and a half of microbacter until the diatoms are gone and resume with the vodka.

FWIW, I also run pelletized GFO in a reactor, changed monthly +/-

Yes it works...
But it is not reef safe.

It is lanthanum chloride and it is needed mechanical filtration with water floss (skimmer is not enough good catching lanthanum-calcium-phosphate precipitation) and it is needed diluited dosage with peristaltics to avoid lanthanum withiut reaction or to avoid reaction in the display tank...
It is needed make the lanthanum dosage in a special chamber or reactor...

I thought you werent suppose to run GFO while dosing? Dont know why, Just what I read. Would like to know.
 
JK5,

I have put it in my tank 3 times in the last 2 weeks and have not seen any effect at all on anything in my tank. Ive only seen some of my sps get more color... Nothing bad at all and on the bottle itself says reef safe.

Polyp extension didnt even change.
 
I know with Zeovit there are alot of reported cases of cyano, take a look at their forum. I assumed this was mainly because of overdosing of AA but it could have something do to do with carbon sources as well.
 
Cyano outbreadks when dosing a carbon source (vodka ,sugar, vinegar, etc) are reported with some frequency. Wether the cyano feeds off the carbon or results from some related microbial activity such as bacteria that die or produce by products is unclear at least to me.

In my experience any cyano associated with dosing vodka, vinegar and sugar has been minor and not long lasting.

I use gfo and dose vodka vinegar and sugar simultaneously. There is no reason not too except perhaps that the phosphate removed by the gfo will not be available to bacteria if you reach 0.00ppm.

The commercial liquid phosphate removers are undoubtedly lanthanum chloride which precipitates phosphate and leaves it in the tank in precipitated form. The lanthanum will build up to exceed nsw levels with unknown effects on a reef tank. The cloud of precipitant produced has been know to damage fish by clogging their gills and irritating gill tissue. Lanthanum chloride works but does require care and fitration of the precipitant.
 
having the same issue, nitrates went down after 2 weeks but PO4 reduction been slow....algae growin in some areas in the tank on t rocks

I´m agree with tmz at one hundred per cent.

Lanthanum chloride tested six months...

no problem if you make little po4 removals (0.01 po4 each day, until you reach your desired values).
Very important... no dosing in the tank...
lanthanum must be dilluited and dosed in 24 hours in the lanthanum reactor filtering with water floss...
Water floss is good enough catching precipitation.

Ya hace prácticamente seis meses desde que empecé con el ensayo de adición del Cloruro de Lantano.
Hasta el dia de hoy mi experiencia ha sido de lo más positiva, ningún animal ha mostrado sintomas negativos achacables al Lantano, y la reducción de fosfatos es totalmente efectiva. En mi opinión, estamos frente a un producto "reef safe" en condiciones de contención.

Os presento una idea de un diseño muy sencillo que funcionaría bastante bien, y que lo haría de forma óptima si metemos una pequeña bomba de recirculación dentro de la cámara de reacción.

El aditivo que estoy usando es le siguiente:
10 gramos de Cloruro de lantano heptahidrato (LaCl3 7H2O)
1000 ml de agua de osmósis

En función del litraje de nuestro acuario, y de la cantidad de fosfato que necesitemos exportar, añadiremos más o menos cantidad de LaCl3 7H2O
Actualmente y para mi sistema de 1000 ltrs brutos, estoy aditando 100 ml repartidas en un total de 24 dosificaciones.
Recomiendo empezar con adiciones bajas (10 ml), y controlar los fosfatos a la salida del reactor y la columna de agua. La presencia de fosfato en el agua del acuario nos dirá si vamos bien o no.
No es recomendable que el fosfato baje de 0,003 ppm en la columna de agua. La presencia de fosfato, nos indicará que estamos agotando totalmente la reaccion LaCl3 7H2O / P.

La mejor opción para aditar el aditivo de LaCl3 7H2O es mediante una peristáltica y en dosis lo mas frecuentes y pequeñas posible.
