I recently started having a brown algae problem. My tank has been established for over a year and while some brown algae used to appear occassionally it was never that bad. Now within two weeks of wiping down my tank brown algae is covering all of my plants and rocks. I assume the outbreak is because I recently switched from live plants back to artificial. Anybody have any ideas to get rid of the algae other than going back to live plants?

Your algae problem likely extends from having too many nitrates in your water. You can try water changes, feeding less, less light, and some nitrate reducing filter media. These may help, but there is no guarantee. I have battle the stuff before and it seemed to just go away on its own though I am sure there was actually a reason for it.

My Nitrates never get above 10 ppm. My tank is understocked and over filtered and I do frequent water changes so nitrates are almost always non-existant. I do leave my light on for about 15 hrs a day, but a lot of what I read says brown algae occurs in low light conditions. The stuff I am talking about appears as a brown slime that covers everything, rocks, artificial plants, glass etc.

The fact that you took out the live plants means the aquarium now has more nutrients for the algae to thrive on. You may want to try feeding less and leaving the light on for 12 or fewer hours a day.

I recently have been attacked by this stuff in both of my tanks. Its growing on my live plants and sand in my 10 gal, pretty vigorously too. In my 55gal its only showing up in spots. So would your last reply go for me too John? This 10 gallon tank is rediculousy to clean. It seems almost every day when I get home from work there are tons of little black specs all over the white sand. Maybe the tank is over stocked?

Is is black or brown? If it's brown, it could just be diatoms, which happens in new tanks, and should go away. The MTS also eat it.

Yeah its definitely brown. Very unsightly The MTS in my 55 seem to keep the sand very clean (thanks DK) I'll have to capture some of them and put them in the 10.

It sounds like the same problem I had when this post was started. My problem was definatley a light issue. I reduced the time my ligth is on to about 4-5 hours a day, and my problem went away instantly.

Hi, One of the things that plague many aquarists is algae. There are many types and great advise from other aquariumites on how to deal with the problem.

Many test kits are sold to help you maintain a stable aquarium. However one kit that many aquarists do not use is a silicate test kit.

In a freshwater tropical aquarium if the silicate levels are to high it can sometimes lead to unwanted algae growth.

Where we live I am lucky as the tap water is near perfect. Mid pure, mid range to hardness with a neutral PH of 7.0.

There are several fish that will clean and keep your aquarium free of algae naturally. Just like if your aquarium is infested with snails just add a clown loach (Botia macracanthus) within a week the snail problem will be gone for good.

Regards

Peter

Hi, one of the problems with aquarium flourescent tubes is they should be replaced once each year. As they get older they loose spectrum along with long hours switched on will in most cases lead to algae problems.

Cleaning off algae in the aquarium can further compound the problem as dead algae raises phosphate and nitrate levels.

Some friends have even remarked "we had an algae problem, now it is gone" after looking at their credit card statement a week or two before the algae started to recede they had paid a visit to an aquarium shop to purchase new flourescent lighting.

Over my large aquarium fitted a small skylight. This gives subdued light all day, spectrum never changes, On moonlight nights aquarium is illuminated with moonlight.

So apart from the aquarium lights being on for just a few hours each day you could say the aquarium receives subdued light (including moonlight) for a period 17 hours each day. Something that is not advisable with normal lighting.

Regards

Peter

Fwiw, using Nerite or Mystery snails can do wonders for diatoms. They love the stuff and eat it voraciously. Neither one can reproduce in your tank. Nerite eggs are not viable in fresh water, they need marine conditions to hatch. Mystery snails lay eggs out of water, where you have control over whether or not they hatch.

I find snails the most useful of clean up crews in any tank.

Otos would eat it too, but then you'd have Otos who need algae to eat.
