View Full Version : Help me with lighting

Hey everyone, first post here.

I have a 50g long that I build into a Malawi tank just recently. I used to keep Tropicals in it until I decided to change it over.

Anyway, my problem is with lighting. I had a dual 48" light bar with the tropicals that worked great. When I tired to use the same bar with the Malawis (sans plants), an algae bloom occured. I now swapped to my other light bar, which is a 24" dual. Only problem is that it doesn't light the tank or show color half as well as the 48" bar (duh). I am assuming I am going to need a single 48" bar... or is there something I can do to prevent the alage bloom with the dual? I would prefer to not have to buy another bar if I can help it. Thanks :)

Algae comes mostly from too many excess nutrients and somewhat from too much light.

Did you have live plants in the older version of the tank? They could have been out-competing the algae for the excess nutrients.
