it will make it, I did that with 2 of my OEBT months ago. One seemed to be missing a leg or 2, but next molt was fine. They live and are still going strong I found mine to be low GH, so I raised my TDS up a little and made sure my gh was no less than 5. never had this issue since. I also thought I might have been giving a little to high of a protien diet so I also feed calcium suppliments in spinach more often, and dose with Calcium Mont every water change. A nice size pinch.
What's your KH if you don't mind me asking? I think my issue was/is a combo of GH and KH both high. I'd like to get the GH back down to 6 since everyone was molting great then and get that KH back down to 0 or 1. I also think they just aren't too keen with my tap water so I'm going to be switching that tank over slowly to remineralized RO. I feel like I have a lot more control over that than the tap anyway.
