I am confused now. The Saechem constant reader indicates that the pH is very low, and an API tester indicates that it is very high.
One Otocinclus was dead yesterday in the morning, maybe by tannic acid from the wood, so I changed 50% of the water and tomorrow on friday I will do it again.
Everything looks normal now, except for the pH reading. We may have to get a new tester.
