started PMDD and CO2 today
Well, I probably won't be moving in a few weeks like I planned since GE
ended my contract this past Thursday. So, instead of waiting, I have gone ahead and mixed some PMDD solution following the directions on The Krib and started my DIY CO2 again until I can get the pressurized system. I use two large wine containers. Each one is 3 liters filled to about 2.5 liters after the ingredients are added. Last time I was using this, my PH leveled out around 6.8. Should this be enough CO2 for a 75 gallon? Also, at what point would it be ok to increase my light duration during the day now that I've started CO2 again? Currently, as I've stated in other threads, I have a Coralife 4 x 65 and run the 2 10000K's for 10 hours and the 2 6500K's for about 4 - 4.5 hours a day. Also, should I wait until my PMDD levels have leveled off and my PH is stable from the CO2 before increasing light duration? thanks a lot. |

Last time I was using this, my PH leveled
out around 6.8. Should this be enough CO2 for a 75 gallon? Depends on your KH. If you don't know your KH, what pH is your tank without CO2 injection? Also, should I wait until my PMDD levels have leveled off and my PH is stable from the CO2 before increasing light duration? IME, no. Once you increase your lighting, your plants will use a lot more PMDD and CO2. So you'll have to find the balance all over again anyway. Leigh http://www.fortunecity.com/lavender/halloween/881/ |

Without CO2, my PH stays around 7.1 - 7.2 maybe a little higher as best I
can tell with my test kit. My KH before CO2 was staying around 2. "LeighMo" wrote in message ... Last time I was using this, my PH leveled out around 6.8. Should this be enough CO2 for a 75 gallon?

And you might find it difficult to keep enough CO2 in the tank once you increase the lighting. With a 75 gallon tank and high light, DIY CO2 isn't easy.

I hear ya. Hopefully soon I'll be able to get a pressurized system and take
my tank to the next level. =) thanks. "LeighMo" wrote in message ... Without CO2, my PH stays around 7.1 - 7.2 maybe a little higher as best I can tell with my test kit.
