Amit, CO2 concentration is more important than bubble rate. Look at http://www.thekrib.com/Plants/CO2/kh-ph-co2-chart.html<http://www.thekrib.com/Plants/CO2/kh-ph-co2-chart.html> to see what your CO2 levels are. Some people recommend them as high as 25-30 ppm. ----- Original Message ----- From: Amit Brucker<mailto:amitb@gtek.co.il> To: aga-member@thekrib.com<mailto:aga-member@thekrib.com> Sent: Friday, October 24, 2003 1:53 PM Subject: [AGA Member] CO2 second round.... Well.... I've replaced the bottle today... this time one bubble per 5 seconds. See how it goes. If it will run 10 weeks constant = I am happy 10x for all the tips.
