I have brown algae in my tank and cannot seem to get rid of it. Quoting from information found in one of the post
Low lighting and high silicates are often the causes of this growth. Removal is done by increase of light level but they may disappear as your tank matures
What I don't understand is how much lighting is needed? How do you check for high silicates? How do you remove silicates if levels are high?
I have a 55g cycled tank, 1 1/2 years old.
Ph 7.2; Am 0, Nitrites 0; Nitrates 10
Water changes every 2 weeks (I've been treating ich the past week so, have been performing small water changes every 3rd day primarily to vacuum gravel.)
Currently treating tank with salt
Filter: Emperor Bio-Wheel 400
Lights: 2 15w bulb. Do not know type of bulb but lighting came with the Petsmart "complete startup" package, so I'm guessing its bottom of the line. Lights are left on for 12 hrs / day.
Incurred heavy losses last week so currently tank has:
3 Bosemani Rainbows
2 Cherry Barbs
3 Black Neons
3 Emperor Tetras
