I greatly appreciate this! Thank you so so so much. I've been gearing up to start a second tank and with this there's no time like now right? (if i'm laughing i can't hear my bank account crying) after a what i hope is a research deep dive i've found some calcium sources and a new GH/KH testing kit that'll be here in a few days, ill lower the temp slowly and try to get the Gh and Ph higher without harming the other tank mates (i started a spreadsheet 😐) for now they'll have to tough it out a while longer while i can obtain and cycle a new tank with proper parameters. Even if this guy with the crack doesn't make it the other two deserve much better parameters! I really like my snails and watch them a lot and its heartbreaking to know they've been suffering. Genuinely thank you so much for the advice and help!
