PH level suggestions?

[logan5]

I've got me a brand new (at least to me) automated Co2 setup.  So, I guess the question is now .. what PH level should I set the PH controller to?  I've got a well planted 37 gallon cube with 6 Angels, 7 Ottos, 10 Cardinal Tetras and a couple Platties.  Now that I can pretty much "Dial In" a PH, what should I be setting it to?  From what I've read the Angels like it somewhere in the low - mid 7's while th cardinal tetras like it in the mid 6's ... so maybe around 6.8-7.0?

Any thoughts?

thanks

Sounds like a plan!

I would do the same as you and I think the cardinals adapt better than the angels so either in between or what the angels like.

AIM for 30ppm co2 to keep the plants happy.

Depending on the water parameters getting to 30ppm could cause a major ph swing/drop.
