Brown algae/diatoms

I have some brown algae growing on some plants, driftwood and slightly accumulating on the surface of my substrate. No other algae issues.

It is a 10g tank appromiately 1m old. Cycle is complete, with current conditions of 6.2 pH, 0 Ammonia, 0 Nitrite, 0-5 Nitrate, KH 2-3, GH 4-6 (supplement very soft tap with baking soda and Seachem Equilibrium). The light is a 20" Fugeray elevated ~5" off water surface. Excel (1ml) dosed once daily, alternating EI macro and micro nutrients.

The tank will be stocked next weekend with CPDs, Burmese Rosy Loaches (Yunnanilus sp.) and one other nano fish native to Myanmar (D. tinwini or Microdevario nana).

Will shrimp help get rid of this algae? I picked up some small shrimp (presumably wild-type Neocardinia or similar) today in the hopes that they would. The Amano shrimp were just too big for the scale of my tank. I would prefer not to bump the Excel - as I think that my dwarf chain sword is already suffering from it.

Hi, I had shrimp and they were eating that algae, but do not count on them if you have a serious infestation. I had a serious infestation, on a newly started tank, i was removing manually what I could once a week, and doing water changes weekly.

After 4 months the diatoms disappeared.


Plants and algae grower.

IME, even Ottos + amanos cannot solve an algae infestation. They can help control it though. Diatoms will go away on their own, just keep WC. My tank is also dealing with a recent outbreak after i disturbed my substrate a ton. It really has taken its toll on all my plants. Pretty sad but i hope it will be gone soon. I also have 3 amanos and 3 ottos in my 10 gallon. the amanos although big, arent taht large of a footprint to have and its a great addition. Ottos i may need to move to another tank eventually since 3 is a lot for my tank but still they are so small and i am relatively understocked otherwise...

water changes. pretty sure all new tanks get the brown algae in the first few months. It can be gently rubbed off with your fingers or a toothbrush, then do a water change to grab whatever debris you can. Don't sweat it, its normal
