Conner;2746306; said:I use the drip method, but that's just because the stores where I get fish from have a fairly neutral pH, whereas I have a south american setup with lots of driftwood that keeps the pH around 6.4. I would be worried a pH difference of .6-1.0 would be too much for an already stressed out ray to handle. And its not really difficult to drip acclimate, at least if they're a smaller ray. I'm sure the larger ones would be a different matter.
With my new tank, I won't have the pH difference, and the water will be fresh and not dirtied by any other fish, so I will probably just dump them in when I get them.
i can test ph in bags , to compare ?? good idea ?
