SM> I hope someone can help me on this one. I operate a 72 gal cichlid 
SM> tank. For about 3-4 months I had no problems growing an abundance of 
SM> water lettuce in my tank. Within the last few months, the plants have 
SM> become stunted, and have alge going around them. I have no direct 
SM> sunlight on the tank, and have kept the temp around 74-80 F.
I've had a simular problem but years ago.  I needed to change the water out.
Hope that helps!
