    I just got back from college to find my parents 55 gallon tank covered in brown algae. What is the cause of this? And what should I do to take care of it? Should i consider ottos? Thanks for the help!

    First step is checking the ammonia, nitrite and nitrate readings, most notably nitrate.
    Is this FW or SW? That will have a bearing on which algae you're dealing with.
    What is their water change and cleaning schedule like? Lighting? Plants?

    Ill get those readings tomorrow. Its a freshwater tank. They really dont do water changes, im working on them to get it more consistent. The last one was a month ago. There are no plants and im not sure on the lighting yet but i think its a t8 bulb.

    That could be the problem right there. A buildup of nitrates and other matter from a lack of water changes will cause algae growth.

    Now that weve figured out the cause what should i do to get rid of it? Just scrub it, ottos, or something else?

    Scrub it and then for it to stay away do more consistent water changes Otto's won' t help it their specialty is green algae. Also I would recommend small plecos Otto's will clean all the algae rapidly and then will starve to death. Mine died a month ago I had him for 3 to 4 months.

    Basically your formula. :)
    Give it a run-over with one of those mag-cleaners, maybe rub it off plant leaves...and do more water changes. Live plants would also help use the nutrients currently feeding the algae.

    Now, there is a chance it could be diatoms. These will pass in time and are common in newly-cycled tanks for whatever reason. Basically the same treatment, though an increase in light may help. For some reason diatoms seem to like low-light conditions.

    Before considering adding to the population, knowing that the tank is not given much in the way of maintenance, is a formula for disaster.

    Is this a light dusting of brown that is easily removed by swishing your hand near a covered object or with a light rubbing? If so that is definitely diatoms. If this is a newer tank, then it can be expected. However, it sounds like the tank has been running for some time now. With that in mind I would:

    *Replace the light bulbs if T8 or T12 and it has been longer than 6 months. Do not use actinic or 50/50 type bulbs. Actinic phosphors are used to grow algae on purpose. Also, purchase a timer and set it so that the lights are not left on all day and night.

    *While you are at home do partial daily water changes, with a deep gravel cleaning to lift all the built up debris.

    *If tank has any measurable ammonia or nitrite, consider purchasing another filter to help create additional areas for bacterial colonization.

    Good luck helping your parents gain control over their tank.

    I was able to test the water. The results were 8.2 ph, 0 amm, 0 nitrite, 80ish nitrate. I havent tried to clean it yet but i will soon.

    Yeah, that level of nitrate will feed algae growth and eventually make fish sick.
