Would the type of lighting be a factor? I am thinking of changing the
halogen lights for fluorescents anyway as the halogens produce too much
heat. Would this help the algae problem?

My halogen spots don't cause a problem. They are on for about 16 hours
a day. I don't use fluorescent lights. Maybe they are your problem.

Dunno, fluorescents are the standard for fish tanks, they aren't
generally known for causing algae problems.

Maybe I'll have to add a Plec and see if that helps. They are supposed
to be good algae eaters.

I've got the same problem as you in my Malawi tank...it's a bit like a green
carpet on the rocks and substrate. It's not slimy or anything so does seem a
little bit like hair algae - it's a very bright green. The front of the tank
needs doing a couple of times a week. Ammonia is 0, nitrite 0 and nitrate
around 10. Of course there are only a couple of plants. Do a 10-20% water
change each week.

I've got a Pl*co but although he is working on the back of the tank the job
seems to be beyond him.....

I'm wondering if it is Phosphate level after reading Tim's posting (thanks
Tim)

I'll continue following this thread. Please let me know how you get on
