    As long as my fish do not go to the surface at anytime of the day, and my plants are bubbling then I'm ok with the CO2 injection.

    Current settings: 1 bubble per 2-3 sec

    I do not measure PH or CO2 level. Save the cash for nicer plants, fert., and fish []

    the dennerle handbook has some interesting values

    neon tetras show no sign of discomfort at 100mg/l of co2
    black mollies still feel very comfortable at 500mg/l
    guppies breed happily at 800 mg/l

    quoted verbatim

    1mg/l = 1ppm

    Nope, I don't buff my water. I dun have coral chips or add any KH power to my tank.

    But I trying out something, placing calcium tablets in my tank. See if got any good / ill effects. Else I have been running like tt for the past 3 yrs of my aqurium life.

    I only have a NO2 test kit, which i use only when i come back from camps.

    My fishes/prawns/pelcos are not affected so... I'm NOT going to fiddle ard with anything. They happy, I happier []

    Tank size 35" X 16" X 18" abt the standard 3 feet tank size

    1 bubble / 2-3 sec is controlled by Dulpa regulator. Can control down to 1 bubble / 15sec [suppose, but too little]

    Different tank has diff bubble rate, but i find tt my 1 bubble/2-3 sec is good enough for my tank,

    min CO2 injection = less CO2 use + bubbling Riccias, and plants

    And more importantly, if I forget to turn off at night, I wouldn't risk killing my fish, prawns and plecos []

    I'm saving for a soleniod valve, and get it just before I go in NS. []

    Bubble depends on yr plants requirements, fish load [more fish, produce more CO2], and type of plants.
