Thank you!
Growing ground cover plant look easy... until now...UG is a difficult plant. I hope to succeed...
For CO2 I use 4 bottles, (apox 0,6 G each):
2 bottles connected to the external reactor. A bottle from these is changed once a week with a fresh one.
2 bottles for a CO2 diffuser. A bottle from this is changed once a week with the bottle come for external reactor, (the replaced one). So I make a new bottle every week. The reaction takes about 3-4 weeks (it depends on the temperature) , but in a first 2 weeks are stronger, so I put freshest bottles to external reactor, and oldest to CO2 diffuzer. I have about 2 bps in reactor and 1 bps in diffuser all the time...
