Help new guy understand Ph adjustment
About to set up a 60 gallon tank with heavy plant growth and driftwood. I plan on CO2 injection and lots of guppies, which require harder water. I'm shooting for a Ph of 7-7.3, hardness of 8- 9 and alk of 4.
My outdoor faucet water, after 36 hours sitting has a Ph of 8.2, hardness of 7, and alk of 4.1. So I need to lower my PH by 1, which seems like a lot.
After some research I have come to the preliminary conclusion that I need to go ahead and get the tank planted, start the CO2 injection and THEN see what my Ph level is after the CO2 and driftwood has had their affect. Am I correct? Or should I adjust the water with chemicals or a natural method beforehand, which unfortunately will also lower my hardness, which I need for guppies.
I have RO water in the house but also a water softener, so using this water to lower Ph will also lower alk and hardness, so that adjustment method will cause more issues.
I'm hoping that the CO2 and driftwood in the tank will lower the PH by 1. Is that possible? Is there a way to predict the CO2 affect on the Ph of water?
