Perfectly normal to see this during a cycle and should clear up on its own when your tank is properly cycled and everything gets back into balance and the silicates are consumed.
Are you doing a fishless or fish in cycle?
Ways of dealing with brown algae without just waiting it out.
- Simply clean it off the surfaces. It will wipe of quite easily.
- Water changes as you suggest. This will remove nitrates and therefore one of its food surfaces.
- Turn up the lights. Green algae will algae will out compete the brown algae. Green algae is easier to deal with. Many more aquarium species will eat green algae than brown, or going with real plants which can in turn out compete the green algae.
Thank you! I have a NICREW LED
light on full power about 8 hours a day. I just did a 25% water change and gently wiped off the plants, still a bit there but much improved. I am doing a fish in cycle this time. When I first set the tank up a couple of months ago I used bottom shelf products and it just didnít work out, I stocked 8 fish and 6 of them died within a month. So I started this cycle about two weeks ago with seachem stability and Iím starting to see my levels go down a small bit. Hopefully on the right track, and also havenít lost a fish in a few weeks.
