Anyones' successful BGA treatment methods please

[frannyscho]

I found this on another site...

"Treatment with 200 mg of erythromycin phosphate per 10 gallons of water will usually eliminate blue-green algae but some experts feel it may also have adverse effects on the biological filter bed. If erythromycin is used for treatment, ammonia and nitrite levels should be carefully monitored"

Can anyone tell us about this stuff and how does it affect the filter hence needing the readings?
The other method I read about was 5-7 days of darkness with water changes (how? in the dark?), are you supposed to feed them in this time? Does it work? Is it kind to fish?

coz I've got BGA too.

What are your water parameters or stats.

I will do some in the morning and post them. I think they were Am 0, Nit 0, Nat 15ish last time.

Extratct from pinned algae article - Relevant for nipping it in the bud if it reappears after eliminating it.

"I have had good results with Maracyn using another method. I recently witnessed a little BGA build-up between my substrate and front glass. I split a 400mg Maracyn tablet in half, then one half I broke into 8 small pieces. I placed each piece in the infected areas using tweezers. A couple of days later the BGA had completely disappeared. Now I slide a credit card between the glass and substrate every week just to ensure it doesn’t reappear. So far so good (8 weeks on) and I still have 99 ½ tablets left!"
