Green algae growing

Haha didn't realize it was a fish antibiotic too

Which snails eat this brown algae (is it diatoms?) or the cyano?

For scraping off, can I do that in the tank and let the filter clean the material, or should I remove each item and clean outside the tank?

 

[howmanyds]

Which would help clean up the brown or green algae faster: bristlenose pleco or snail of some kind?

 

[Freakgecko91]

Bristlenose

Do they clean up cyano too?

Would a bnp bother my three small synos?

No and more than likely no

Cyano is a pain, had a major outbreak in one of my nanos, but I tore that tank down anyway, not sure how to get rid of it

The only way to be sure to kill all the cyano bacteria in a tank is to do a 5 day treatment of Erythromycin. First you want to vacuum or remove as much of the cyano as possible then start your 5 day treatment. On day 6 do a 50% WC. Erythromycin won't harm BB but if you have a lot of dying cyano you can have an ammonia spike which is why you want to do a large WC after treatment. Many people use Maracyn but any Erythromycin sold for fish is perfectly fine to do.

Rarely will any fish eat cyano. It actually releases toxins and is nasty stuff.

Be sure your nitrate levels are at least 10ppm as cyano low levels makes a tank easier for cyano to get established in.
