Hey there!
Just wanted to update my status! I've ordered the plants and i'm expecting the delivery by this thursday or friday. Pretty darn excited bout it now!!

By the time i get the plants i wanted to build my own Co2 setup...so i was reading alot on the subject.

After various comments on the venturi reactori came up with these observations which other ppl have experienced:
1. Burp hole usually doesnt serve any purpose as Co2 escapes from the powerhead itself when the powerhead is shut.

2. Some amount of Co2 escapes from the container due to the force of the Co2 diffused water from the powerhead to the container.

Also, i do not plan to use the powerhead for more than 10-11hrs a day (equivalent to the photo-period i provide)

So i've come up with a slight modification to the design and i hope i recieve a few comments/changes to make sure i do it right the first time itself!!

Also regarding the Co2 generator setup, i've come up with a representational diagram and need to know if i need to add any other component to it to make sure its safe! I'll be using a 200ml mineral water bottle for a bubble counter/gas seperator in the generator setup.
