DYI CO2 for 36 Gallon Tank
Need advice, sort of new to CO2 systems, I am planning on making my DYI C02 system this weekend. After reading few articles I am still unclear about following:
1. Is one 2 liter bottle enough to supply sufficient C02 levels for rich growth in 36 gallon tank?
2. What happens once a mixture runs out and no replacement bottle has been used, does the Ph drop dangerously low possibly killing fish? Any way to avoid this?
3. Where can I find tubing specific for CO2 gas, I cannot find any in my LPS?
