Hey all,
I recently grew mysid shrimp in a plastic tank. The only things in the tanks were pumps, pipes, a few nets, and heaters (no sand or other substrates), and uneaten artemia food. On the second day of the experiment, the pH suddenly dropped: from 8.2 to 7.4, then returned to 8.0 the next day. On this day, the dissolved solids were also at their lowest level of 20.92ppt (usually they were closer to 24ppt).
Is there any reason the pH could have dropped so suddenly? I think the CaCO3 precipitated out somehow (since both pH and TDS dived simultaneously), but cannot for the life of me work out how. I haven't used aquariums very often, but didn't alter anything on the day when everything crashed. I would be grateful of any help.
Thanks
