So, my 20L planted shrimp tank which is fully cycled but fairly recently occupied my shrimp (4 days!) seems to be going well so far. But I have a question about the GH
I only just started measuring these (oops) and I note that my flora base pro substrate is keeping the pH nicely at 6.5 but when I tested the KH
yesterday it was <1DH. After a water change (50% as an experiment) today the pH remains 6.5 and the KH
is now 3DH which still seems quite low (ie are my shrimpies getting pickled at night time??)
The substrate is flora base pro.
Should I be adding some sort of buffer to prevent pH spikes at night when plants respiring and if so what?
Here's a picture of one of the inmates because reasons.
