I just set up my new 12 gallon for my betta, I used the Oliver Knott AquaEarth - everything seems fine so far except that it dropped the pH significantly, to about 6.4. The tank my betta is currently in (which doesn't use this substrate and is cycled) has a pH of 7.4, and so does my tap water. I might be jumping the gun here but I'm worried that if I do a water change with the new tank it's going to cause the pH to fluctuate too much, and could stress/kill my betta once she's in there. I'm also worried that the tank won't cycle at a pH this low, but all the articles I've seen online give conflicting information. Any help would be appreciated!
