Brown Algae?

My tank has been set up for a few weeks, and now there is like an outbreak of brown or goldish algae. Not sure what it is where it came from. My water tests all come out ok, so not sure if this is normal or not. What can i do to get this under control?

Thanks
TC
 
dealing with the same issue. inverts from the group buy will be delivered on Feb 26th. not sure if i have so much in me to stomach 25 days of it. i havent had any fish in the tank, no feeding, no nothing and the brown diatoms appeared. i bought a few snails and they made some progress. but i will need an army to clean it completely not a few brave soldiers. Cerith snails --- if you find a good deal on them - please let me know.
 
So if i add some snails and hermit crabs, they will help to control this? Its annoying that i've spent 4k and my tank looks disgusting.

To simply answer your question; yes, there are some snails (Trochus and Astraea are two that come to mind), that eat diatoms. I know some crabs do as well, but not sure about hermits though.

The other things to consider, if the tank has just finished its cycle, and there are no corals in the tank, reduce the lights, or better yet, turn them off all together.

You didn’t mention your water source, but diatoms thrive on silicates, nitrates and phosphates. If you are not using RO/DI water, consider doing this as well. If you are using tap water, that will continue to “feed” them.

Otherwise, it is a normal thing new tanks go through after cycling….to be followed by other micro and macro algae.

A tank of only a few weeks old is still going through a cycle. So brown algae/diatoms is a normal part of a new tank process. Even though it drives you crazy, resist the urge to checmical it away. It will go away all by itself as your water chemistry comes together on its own.
 
pgordemer is right, if your tank is only a few weeks old its most likely still cycling and it will go away, but in the future as a preventative measure you can dose algaefix once a week to help keep the algae under control. good luck with the new tank.
 
I have a new 55 tank a couple weeks old and I have the same thing.. It happened to my first tank and went away after about 2 weeks .
 
Most new tanks go through several "cycles". The algae cycle can be one of them. If it's on the glass, scrape it off. If it's HA (hair algae), and you can easily reach it, yank as much out as you can. Reduce feeding and lighting, keep the water as clean as possible, several small water changes may help (with RO/DI water), but most importantly, BE PATIENT. Do not go super crazy and totally overstock on a cleanup crew, because once the algae bloom is over, you may risk losing some since there won't be anything left for them to eat.

Like I said in the beginning, it can happen to anyone. Look how my (old) 75 looked even after it was completely "cycled". ;D

Can you say "Welcome to my jungle?" It all went away....overtime...with patience. ;)
 
If I would see something like that in my tank now, I would need a mental help. i have put too much heart and $$$ to go through something like this. I am winning my battle with brown diatoms right now, but not sure if I am ready for any HA yet :)
 
My hair algae started popping up AFTER I had won the battle with the diatoms. ;D That doesn't mean you'll get this, Rafal, so don't start ripping your hair out - yet. I did go kind of fast with my 75. I was SO lucky not to have lost any lifestock due to the green stuff.
 
I am on my 4th week of the hair algae bloom and its slowly going away. I can take out a rock now and easily scrub off the algae... it will go away with good maintenance.
 
RO water and monitoring the hours which your daytime lights are on each day... Keep the phosphates and nitrates down and the algae will have nothing to feed off of and it'll starve...
