Wow, how refreshing to hear someone say this!! :)
When even Diana Walstad said in an article a while ago that she was using CO2
on some tanks.... and yet, using her approach re the fertile substrate etc and
NO CO2, works! Its just slower, which has some advantages.....maybe I'll
delay getting that Carbo-Plus unit after all! I'm having fun getting some
more light into the picture, so I'll play with that for a while!
and about CO2 and the algae wars - I too have had several different types
visiting; as Tom Barr says, its a matter of working out what is out of balance
- not always fun, but so far, the plants are winning.
Here's to lots of different ways to grow plants!!
