I have had the tank about 6 weeks and all is doing fine until a break out of brown. I have heard this could be not enough light but the tank is brand new with 2x 20W bulbs and is a 90L Tank. It is also close to a window but the green algae is minimal.
I have 5 Zebra Danios, 3 Neons, 3 Glowlights, 1 Bristlenose Pleco, 1 Cory Catfish and 1 Blue Gourami.
Filtration is good. Underwater in a Jebo R326 Tank.
PH etc is normal and temp about 26-27C.
Does anyone have any ideas what is wrong and if it is brown algae or what? It's starting to apear on my ornaments and the leaves of the plants.
Thanks heaps.
