Brush Algae

[d3tained]

Hi all.

I have a 110 liter tank with 4 WPG ( Consisisting off 4 x 14 Watt 100 Kelvin white lights and 4 x 14 watts yelow lights )

I dose recommented dose of Seachem Flourish at every water change which is about every 4 days.

I also run Yeast Co2 that gives about 1 bubble per second.

PH: 6.9
Ammonia: 0
Nitrite: 0
Nitrate: 10 ppm on avarage.

Tank was running fine for about 3 months untill now about 1 week ago brush algae started to grow on teh older leaves of my plants.Its actually killing the leaves.It staretd when i introduced Cardinal Tetras which in the end all died due to some sickness.I also removed my Ottos from the tank prior to this.

Can anybody please help me?

I know True Simenses eats this algae but in South Africa you cannot fnd it.

Please anyone?

Low NO3 can cause BBA, so if you're able to increase this to around 20ppm that might help. Also, I think your CO2 levels might be low, do you know your KH of the tank? For a tank of that size I reckon you'd need 2 bubbles per second. Low CO2 will definitely cause algae.

Thx!!

My problem is def low C02 levels so what ive done for a test is just decrease light period and WPG.

THX FOR THE ADVISE!!!
