    Hi Guys,
    I need some help from the old thread. I started my tank with ADA Amazonia (first time with ADA product), my PH before CO2 injection is about 6.7, KH = 4. If I push for 1.7 drop, it would PH = 5. Wouldn't it be too low? Should I raise the KH which or should I stop at PH 6.2 as described in the above posts. Comments are welcomed.
    Cheerio,

    Ph is not toxic, where as co2 is does. Meaning if you pull the ph till 5, but your fish is fine i suggest you keep that way. More co2 is better for plants, don't limit your co2.

    The only limitation is your fauna, since it's considered toxic for them

    Hi Milk_Vanilla,
    Thanks for the update.

    I have another question, I took a sample of the water out of the tank and shake it up and left it outside for 1 hour, then I tested the PH = 7.8. Should I use this value 7.8 and compare it to when the co2 was injected into the tank or Should I stick to my above where it was 6.7 before co2 injection within the tank and compare it to when the co2 was injected? I found it a little strange since I understand that ADA will buffer the PH but I don't expect the buffering be gone after I shake the water up. Isn't the disparity too great? Any kind soul able to explain this to me?
