Co2 Noob need help, PH plummeted will this kill my cycling efforts?

I Just added co2 to my first ever planted tank. the PH was 6.5 or so, and now after about 8 hours is at the bottom of the scale 6.0 or lower. Will this killl all the bacteria? help! Should I add baking soda? I bought malawi/victoria buffer from sachem but it has not arrived yet, and won't until sunday I believe.

My ammonia was finally below .25, nitrites were still around .25-.5 but nitrates were 40 PPM before I did a water change so I thought i was at the end of the cycle.
Should I add baking soda in the mean time to save my tank? I'm planted with asian ambulia, the red "alichee" ish sounding plant whose proper name I forget, and floating salvinia. They may not appreciate the super low PH either
please help me make the decision wether or not to use the baking soda for nowThanks

pH drop from 6.5 to 6 is normal when you do CO2.

Well I know its normal, the question is should I do anything about it. Need the tank to keep it's bio filter, and now I have one danio in there I don't want the nitrites(which are very low but super acidic makes them much more toxic to hurt him) Thank you.

I got the malawi buffer salts in the mail today and could use some of them. I feel like my ideal PH for plant and pea puffer is more like 7 anyway

your fish and bio filter should be fine. Fish and bacteria generally have a much better PH tolerance than many believe.

No need to add baking soda. The pH drop associated with CO2 injection is normal and to be expected.

Your nitrates might be a bit high, so just do a water change and let the cycle finish.

It may be a good idea to consider raising the alkalinity in your aquarium water. Like other have mentioned, there will be a ph shift with CO2 injection, but you don't want to bottom out your ph into the 5's just because a pH shift exists; if you increase your pH when the CO2 injection is off, then the lowest value you dip to will be higher (i.e. 6.6 pH instead of 5.6).

If you are interested in this, you could slowly increase the KH of your water change water and over several weeks manipulate the chemistry in your aquarium. All that matters here is if you are comfortable with bottom level of your pH.

Obsessed? Maybe

You don't need to add baking soda or increase kH. That could cause more harm than good.

CO2 does not impact osmotic pressure, so there's not a need to worry.
