...And walked out empty handed. I finally get enough money, bring down my ph to a stable 7.3 and the guy (who I do trust btw) tells me that past 7.2 a ray just curls up, goes into shock, and dies. Which I would completely accept (it's an expensive leap of faith unless proven otherwise), aside from the fact that a month or so before he said 7.6 is an acceptable ph. My real worry here is acclimating the ray from 6.0 (current tank at lfs) and my 7.3 of my 150, so any suggestions on how to help with that would be great as well (not a newbie to fishkeeping, just rays). My main question is, is that entirely true in your experiences *looks at tnc and aikidoguy*? Any experience or pics would be great, I trust you guys entirely but backup evidence would help convince my family members who haven't had as much time here as I have. Thanks in advance, sorry for the long post.
