One more question

[superjalami30]

Is it caused by a nutrient overload?
I've done some reseach, besides what you guys gave me here and some say its a nutrient problem?
Is this so, and if so, what nutrient?

thanks guys and gals

Very low or bottomed out nitrates is usually the cause of bga also gf has a theory that it eminates from the substrate which i would tend to go along with.

You will usually start to see it between the glass and the substrate and then it will take over sometimes rapidly depending on how bad the strain is.

Your pretty sure its bga?

Well, on the front of the glass, along the bottom there is a brownish algae, I presume diatom.
It just appeared within the last few weeks.
I have done nothing but do a little pruning before this happened, no change in feeding, temp, ar decorations.

The algae I refer to as bga is completely located on my val, near the top of each one where it is closest to the light, as well as on my dwarf pygmy chain, dwarf sag, and anubius.
On the val it looks like dark green sludge, but on the anubius, dwarf chain and sag it looks like dark green spots.

On the val its much darker.
On the pygmy, sag, and anubius it's dark, but only a few spots here and there.

Again, it's very little, not much at all, but enough to make me take notice and want to reverse its spread before it gets out of control.

What is the light and fert regime for this tank are you dosing with EI N,P,K and trace etc?

With Diatom algae ottos will eat it

The Anubias sag and dwarf pygmy sword have Green spot algae this is very common particularily on slower growing species like anubias, it can be caused by lack of Phosphate (probably not in your case i think if i remember correctly you have high levels of phosphate in your tap water) or to much light on these plants particularily if they are slower growing, anubias with green spot algae will do much better if you give them shade and take them out of direct light.

Bga will usually have a very bad smell, if you suspect its bga try the blackout (which i think you are) you may be able to catch it early but in bad cases like houndours this didnt work and she is now trying maracyn the antibiotic, but i would try the blackout first, but you have to correct whatever conditions made the algae appear in the first place or it will return.

And dont be tempted to swap any plants from the affected tank to other tanks to try and save some of them if it is bga this can lead to cross contamination.

Thanks Zig.
Yeah, I'm trying the blackout first.
Again, it's such a small case of BGA, or whatever type it is so I'm not too worried as of yet.
I just really wanted to stop it before its too late.
I dose seachem comp once per week at recomended dose.
KN03 mon, wed, and fri.
K2SO4 same as above.

My Nitrate levels sit at approx 20ppm
C02 levels are approx 20-25 ppm
And I have 2.4 WPG.
I figured the anubius would get some algae on the leaves as all of mine has at one point or another, and it is situated in a darker spot in the tank, hence why it has little algae grwoth.
The sag is in a bright area of the tank, but right in front of a fairly strong current, as is the pygmy chain.

I actually dont think its diatom algae along the front of the glass, I think it may be decaying "pygmy chain sword matter"
LOL
I need to seriously prune it away from the edge of the glass.

Thanks again Zig, and everyone else.
