Guest Posted August 27, 2009 Report Share Posted August 27, 2009 I just wanted to know a few things about DIY CO2. I'm going to use a 60ltr tank and I'm going to make a bubble counter but I just wanted to know how many bubbles per minute there should be? Also would one 1.25ltr bottle be enough for a tank this size or should I have two? Quote Link to comment Share on other sites More sharing options...
SamH Posted August 27, 2009 Report Share Posted August 27, 2009 Also would one 1.25ltr bottle be enough for a tank this size or should I have two? I'm running one 1.25L bottle on my 54L and it's flying along. Got four 18w tubes over it (no special plant growth tubes) and I have a serious algae problem. I don't have a bubble counter but they seem to be popping out very frequently, the pH dropped from above 7.5 to below 6 in under a week and has stayed at that level. But my plants have produced visible O2 bubbles for the first time ever so I'm stoked. So unless you're running decent lighting, don't CO2.

Guest Posted August 27, 2009 Report Share Posted August 27, 2009 Thanks Sam. So you think 1 bottle will be enough. I'll be running about 80Ws of light so that should be enough light. I'll also be dosing with flourish as well as using CO2 so should hopefully have good plant growth. Does anyone know how many bubbles per minute there should be?

SamH Posted August 27, 2009 Report Share Posted August 27, 2009 Excel AND CO2? I think that just one is enough. What type of light may I ask? Quote Link to comment Share on other sites More sharing options...
whetu Posted August 27, 2009 Report Share Posted August 27, 2009 Dosing with Flourish (a fertiliser) will be fine. Dosing with Flourish Excel (a source of bio-available carbon) is not necessary as the CO2 will do that job. Quote Link to comment Share on other sites More sharing options...
Guest Posted August 27, 2009 Report Share Posted August 27, 2009 Oh OK. I just thought that having both flourish (it's just the normal flourish not flourish exel) and CO2 will give lots of different types of nutrients as on the back of the bottleof flourish it doesn't say it has any carbon in it. Not totally sure at this point what lights I'll use. Will 2 normal desk lamps shining down from the top into the tank work or does it need to be a proper full length tank light?

Vinnie Posted August 28, 2009 Report Share Posted August 28, 2009 As far as i'm aware, you want 1 - 2 bubbles per second, but if any one else knows a better rate please say so Quote Link to comment Share on other sites More sharing options...
Zev Posted August 28, 2009 Report Share Posted August 28, 2009 How are you planning on regulating the Co2? If you restrict the flow, it may blow your DIY bottle connections. There is a table here that shows how you measure the rate using Ph and Kh. http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm Quote Link to comment Share on other sites More sharing options...
Guest Posted August 28, 2009 Report Share Posted August 28, 2009 As far as i'm aware, you want 1 - 2 bubbles per second, but if any one else knows a better rate please say so Really. Thats alot of bubbles. I was just going to try and get the mixture of yeast, sugar and water right so it's a good amount of CO2 being produced. In the beggining I won't have any fish in the tank for a while until the plants grow and the fish are ready to go in there so I should have a few months to get the right mixture.

SamH Posted August 28, 2009 Report Share Posted August 28, 2009 Haha, this all seems so technical! I just sealed up the lid of a soda bottle with some airline in it, checked it, chucked it on the filter outlet and let it bubble away. Platy doesn't seem to mind and the Rams 'n' Ottos seem unaffected. Quote Link to comment Share on other sites More sharing options...
Vinnie Posted August 28, 2009 Report Share Posted August 28, 2009 Sorry missed the DIY part of the title, as for how many bubbles i said- thats what I was told to use.

I'm just using a normal 1.25ltr bottle that has a lid that I was using for hatching BBS with a bit of airline tubing that goes into a little clear container that has some water filled to about 3/4s of the way up so I can see the bubbles going into the water. The another bit of airline goes from that little container onto a diffuser that will go into the tank. It sounds more complicated than it really is.

Vinnie Posted August 28, 2009 Report Share Posted August 28, 2009 No need to say sorry, just pointing out thats wat some one told me to use... it could be wrong, thats why i'm also keen to hear wat others have to say Quote Link to comment Share on other sites More sharing options...
