Brown Algea (maybe) on tank and ornaments
In the last couple days I have all of a sudden got this brown (rust colored) stuff on the front of my tank, on 2 of the ornaments, and on the filter overflows. I got a light that has been on the tank for like 2 weeks and I try to keep in on 10-11 hrs a day give or take. I did notice a little bit on the ornaments a couple days ago but the glass and other ornament has just REALLY got it since that. I did a water test today and NitRATE was 30, NitRITE 0, Ammonia 0-.25 (hard to tell) and my Ph is like 8. From my last test the only thing that has changed is the NitRate went up 10-20 and the trace of ammonia.
Does anyone know anything about this and/or what to do about it and should I be worried?! THANKS!

How long has the tank been set up? Is the algae just sort of blotchy stuff on the glass? Or is it thicker and furry? If it's the kind that's just sort of splotchy on the glass - I get that a lot on brand new tanks. I think it gets out of control from the ammonia in the water. I've always just scraped it off the glass with a razorblade. After the tank is established and the ammonia is steadily at zero and you're keeping the nitrate in check with water changes, it should keep the algae at bay. Also, do you have the tank in direct sunlight? That will definitely cause the algae to get a little crazy.

Tank has been set-up like 5-6 months now. It is kinda blotchy on the glass and on the orniments it kinda stained them. I just took my glass magnet and one swipe and it was gone off glass. I wouldn't say tank is in direct sunlight. The window is a good ten feet away and is westward facing so it only gets sun now about 5 hrs a day and we haven't had the greatest of sun round here lately anyway

This is the discusting {colorful metafor} that I am dealing with! That Cave used to be a nice color blue. The second pic is of the gravel just below the surface, there are about 7-8 spots around the tank that are the same way. Anyone have any more ideas as to what it is and what to do?!

Yeah that's brown algae. Scrub the glass to get rid of it there. Then during your next water change pull the ornaments out and them a scrub too.

ok, any special way to clean them!? That cave as you can see is a little jaged, I tried to use a tooth brush b4 but it just wouldnt come off. Any ideas as to why now I am getting this and how to control it/rid it? Is it harmful for my fish? They don't seem to be effected! Thanks Tyyrlym

Go to your local lake or river, see how much algae is growing there and don't worry about it. The little bit that is unsightly in your tank is of no concern to fish. Why are you getting it, again others know more than I but from what I understand its a normal part of a new tank and will dissipate with time. There's no real special way to clean it, just get it off however you can. I use an algae brush for my glass, a wash cloth for the plants and such and scrub my caves with a scrub brush, that's all.

How new is this tank? Brown algae is very common in new tanks and tends to dissapear as the tank becomes established.

I set my tank up April 4th I believe. So about 6 months

I have the same problem. It started off just on the glass. I was told it would disappear on its own. After a week its all over my ornaments , gravel, some on the filter,

No direct light either. But my tank hasn't finished cycling so maybe that's the problem . Nitrite is very high right now.
