    it’s having your eye in to do those sort of things, ive got it with fish but not with planted setups, i have tried a few times over the years but they never look like yours do.

    can’t do that Karlos, after JD any tank will look great, it’s next morning i’d have to look at it.

    lets go back to topic….about CO2, how do you calculate the right dose? in a diy

    Usually measured in bubbles per second isnĀ“t it?

    I think it’s bubbles per minute.

    Fairly certain that the calculation of how much CO2 is present in the water depends on pH and kh before and after adding the CO2. The rate of bubbles is then adjusted to achieve the desired CO2 level.

    This link looks helpful.

    Lol this is why I was scared of setting up this forum!

    well i had a diy co2 before, and it came out of a small 1/2 inch airstone…can’t really calculate the flow

    People usually measure in seconds per bublle or bubbles per second – for example I add 1 bubble every three seconds in my trigon. This is irrelevant though really cause every diffuser will add a different sized buble etc.

    Eyrie is right. The amount of CO2 you need to add to your water is dictated by the amount of plants. Generally though, 30 ppm is taken as the optimum for plant growth in heavily planted tanks. The affect on your pH of adding CO2 is also determined by your KH, tanks with a high KH require an awful amount of CO2 to affect the pH where as a tank with a low KH will require a very small amount of CO2 to affect it’s pH. Adding 30 ppm of CO2 to a tank with a KH of 2 and a pH of 7 will have the affect of dropping the pH to about 6.3, whereas adding 30ppm to a tank with a KH of 10 and a pH of 7 will only have the affect of dropping the pH to about 6.8/6.9. This is why you need to be careful adding CO2 to tanks with a low KH as they may well crash (pH drops significantly to less than 6) wiping out your fish!

    There is a great article on UKAPS about this that I will try and link later – i’m at work at the minute. (also didn’t have a chance to look at the link from Eyrie – so that my cover everything!!!).

    To answer malti’s question – if you get a drop checker with a fuid of known KH (usually 5 i think) the colour the lquid turns induicates the amount of CO2 present in the tank (usually blue – too little, yellow too much – green just right) can’t remeber what the colours indicate in ppm (although green is 30ppm) but i can look when i get home tonight.

    Cracking little tank that Dave <img src="style_emoticons//smile.gif” style=”vertical-align:middle” emoid=”:)” border=”0″ alt=”smile.gif” />

    I will definitely have a bash at a proper planted tank, at some point, but tbh I’m as creative as a dead dog.. it’s a limiting factor.. <img src="style_emoticons//smile.gif” style=”vertical-align:middle” emoid=”:)” border=”0″ alt=”smile.gif” />
