Question about Co2 and PH
 
2 Attachment(s)
I have just added a pressurized Co2 system with a PH controller. The chart states that to have a concentration of Co2 of 25 PPM that I must set my controller to 6.8. My question is that can my Loaches and other live bearers adjust to the lower PH. My KH is 6 degrees. This is my first planted aquarium started about 9 months ago.

Loaches are soft water fish, so no issues there, they should be better with a slightly acidic pH. But your livebearers will not appreciate it. You don't mention GH (a KH of 6d would suggest soft but not necessarily), and this is critical for livebearers as it is the mineral (calcium mainly, magnesium) that they need to maintain a healthy system.

Thanks Byron. My GH is generally moderate soft between 5-6 Degress or about 100-120 PPM.

Byron :

I just read part two of your write up. You are very knowledgeable.

Byron:

Since you are pretty knowledgeable, you seeing my tank, Is there anything I need to do differently or should I just maintain what I am doing.

Your aquarium is very beautiful. I would not change your system, since it clearly is working. However, I would remove any livebearers (if they are in this tank), as they will not be at their best. The other fish are soft water and should be very healthy, colourful and lively--as they appear to be from the photos (colourful and healthy anyway, can't tell about lively from a photo:lol:).
