EM treatment,

[Moby]

Where can I find more info about EM aquarium algae treatment?
Not that I need it, just curious.
How effective, against what kind of algae is it? What kind of antibiotics, how is it performed etc...
Thanks.

EM is Erythromycin, an antibiotic that is sold for bacterial deseases in fish, although it is also used for human application. That said, it works also against BGA, since these are also bacteria. It only kills Gram positive bacteria, so it won't hurt the nitrifying bacteria in the tank.

Application is 200 mg per 10 gallons, and after that another 2 days 200 mg per 20 gallons. That should be enough.

Thanks dutchy,
Does it have any negative side effects on plants?
Does it also kill a green algaes like GSA, GDA?

Doesn't seem to work on anything other than BGA. No effect on plants.

Hi Moby,try that link http://fishsupplie-s.com/index.php/Bluegreen-algae.html

About 1/4 of the article is not valid, most is however.

I have a ratio of 3:1 for NO3: PO4.
Never have issues with BGA.
Plenty have had much much higher ratios, say 20: 0.2ppm, or 100:1 NO3O4, no issues as well.
The ratio stuff is manure and has been falsified for algae control issues.

Algae do not care, the plants do however. As long as those levels are not allowed to bottom out or become to overwhelming limiting........then you are okay, I dose about 15 ppm NO3 during/after treatment at least 2x a week.
And of course make sure good cleaning, trimming, dosing is followed up.

Algae is a sign you are doing something wrong for the plants.
It's extremely difficult to add too many nutrients.
CO2? Yes, pretty easy to kill the fish, but not the plants, light/ Easy to add too much for many folks.

Hi Tom,can u tell me what do u use for PO4 measurement?Thank's.

Standard reference then a Hanna multimeter, old days: Lamott and the Hach(mostly).
I do not think I've measured PO4 for a good 8 years now.
