| Re: Algae on substrate I would try some snails and check your phosphates. Is the algae a sort of like a sheet that you can gently remove? If so do it. It sounds like cyano except for the color. Cyano is usually kind of maroon. Could be a different type regardless. If you cannot just pull it out try vacuuming the substrate during your next water change. That can also be very helpful. One last thing. How old are your bulbs? Old bulbs can also contribute. You also have a bit of a long photo period IMO.
Hope that helps. |
