Well going on the levels of my PH & KH, i have only around 1 ppm of CO2
in my aquarium so i will be making a DIY CO2 system.
Is such a compressed system expensive?



what size tank and how much light do you have?. Compressed systems vary in
cost. I bought my regulator for about $90.00 (Cdn) , clippard needle valve
for $25.00 and a few bucks for miscellaneous parts. The tank is a 20lb which
I rent, a one time deposit of $50.00 and $30. to fill it. I simply take the
tank back and they will give me a filled one. I installed this system 10
months ago and have not use up the tank yet. I expect it will likely last me
about 18 months. Depending on your tank size you will need 1 + bottles.
Every charge will be 2 cups of sugar, yeast and baking soda. I run two
bottles in my 33g (one bottle does nothing) so over the course of a year I'm
likely going to spend quite a bit on sugar and yeast. I will be replacing
that system with a smaller compressed system and running separate values to
several tanks. Much more convenient. What size tank and how much light do
you have?. Adding CO2 to a tank without sufficient light for the plants to
use it really will do nothing.
