treating bga with maracyn?

well fertilization with flourish and flourish excel is something that only gets done when im home. As of today, the only bga left in my tank are little strips that have fallen off the walls or decorations and gotten stuck on a plant or another decoriation so it looks like random ribbons of dark green. Still kinda gross, but now its kinda pretty, in a wierd way. So maracyn works, if anyone else gets this problem and cant seem to fix it.

On another note, my fish dont seem stressed at all. if anything, they are more lively, probably because of the water changes. I am going to dose my tank for another two days before stoppign to make sure that the bga is all dead.

so the tank is clean now, save for the tiny scraps of bga i can still find. Anyone know if these bits can come back to life? i hope to stop doing water changes everyday and switch to a weekly schedule but i dont wanna give the bacteria a chance to come back

What kind of filter do you have? and what kind of filter media do you use?

its a fluval canister. I'm using all the default stuff that it came with, the foam, large cylindrical ceramic media, and 3 bags of carbon. Ive already washed the media to avoid having the bga come back from there. Does filter type promote or discourage certain types of algae?

No no .. i wasn't getting at washing .. actually .. I had major bba problem when I had no carbon just bio and mech filter.. and as soon as I added carbon to my filter + water changes.. bba went away in the matter of 2 weeks. Maybe you need to change your carbon? But keep up water changes!

that is very possible. I have not changed my carbon in almost half a year. In all likely hood it stopped working after a month or so, and i just left it as media for bacteria to grow on. I heard that carbon is generally useless so i was never really concerned ab out changing it. I'll give my carbon a change and see what happens. Also i had a bba problem before the bga problem. the SAE killed the bba and the bga appeared. go figure, im defiantly doing somthing wrong. but now it all seems ok... i think.

I am not convinced that carbon filtration will prevent bga. If you read the link you (SinCrisis) posted earlier, it is clear that bga is a biological issue prevented by regular partial water changes and suitable light (i.e., not more than required for the plants). Carbon is not going to have any affect on this.

Several members have posted in other threads recommending against regular carbon filtration in any aquarium. I second their opinion. Carbon should only be uysed as an emergency measure. It removes substances from the water. Used continually, it is removing things that should not be removed; plant hobbyists always recommend against carbon in a planted tank. A healthy aquarium is one that is well maintained and balanced biologically, without chemical intervention. Once you have this cleand it, regular proper maintenance will keep it at bay; I have had it myself.

On another note, I recently (two weeks ago) had cause to use Maracyn in a tank (to deal with columnaris, which it did). I noticed this week that the plants in there are looking less than optimum. As nothing else has changed or altered except the five-day Maracyn treatment, I am leaning to the belief that the Maracyn did something to affect the plants. The link you posted earlier does mention it can affect the biological filtration, so this is not surprising. Anything that affects biology in an aquarim is dangerous as there can be far-reaching ramifications. Another member (1077 I believe) has frequently mentioned never medicating until all else fails. I believe that is sound advice.

My plants seem fine after i medicated my tank. The kind that i got says it wont affect my biological balance. I also did tons of water changes even as i dosed the medicine so maybe that will help?

Let's hope so. We have to trust what it says on labels, but sometimes you do wonder... Anyway, I would not go the carbon route as I said. You'll get this mess cleaned up, and you'll be able to keep it so with your regular maintenance. We all hope you do for sure.

Actually carbon lowers amount of Nitrates, Nitrites in aquarium there for having direct impact on bba or bga
remember ... no food no grow! Bottom line is that carbon detoxifies your water leaving less food for your algae... any algae.

Cyanobacteria: phylum of prokaryotic aguatic bacteria that obtain their energy through photosynthesis. They are often referred to as blue-green algae, even though it is now known that they are not related to any of the other algal groups, which are all eukaryotes. Cyanobacteria may be single-celled or colonial. Depending upon the species and environmental conditions, colonies may form filaments, sheets or even hollow balls. Some filamentous colonies show the ability to differentiate into three different cell types. Despite their name, different species can be red, brown, or yellow; blooms (dense masses on the surface of a body of water) of a red species are said to have given the Red Sea its name. There are two main sorts of pigmentation. Most cyanobacteria contain chlorophyll a, together with various proteins called phycobilins, which give the cells a typical blue-green to grayish-brown colour. A few genera, however, lack phycobilins and have chlorophyll b as well as a, giving them a bright green colour.
Unlike bacteria, which are heterotrophic decomposers of the wastes and bodies of other organisms, cyanobacteria contain the green pigment chlorophyll (as well as other pigments), which traps the energy of sunlight and enables these organisms to carry on photosynthesis. Cyanobacteria are thus autotrophic producers of their own food from simple raw materials. Nitrogen-fixing cyanobacteria need only nitrogen and carbon dioxide to live: they are able to fix nitrogen gas, which cannot be absorbed by plants, into ammonia (NH3), nitrites (NO2) or nitrates (NO3), which can be absorbed by plants and converted to protein and nucleic acids.
