I realize that various sp. of Crypts tolerate/thrive in a variety of hardness ranges, but is there a recommended range or can someone point me to a resource that lists a variety of Crypts and their recommended hardness ranges? Preferably whatever degree GH as the same unit the API test kit is in. Thanks!

My PH is around 6.4 and my GH is around 2-3 on the api test kits. If I add a GH booster, will that also raise the PH due to the same minerals hardening the water? I pump a good bit of CO2 into the water and I'm pretty sure this is the reason my PH is so low. My substrate is an even mix of fluorite and flora max.
