My aquarium consumes indeed lot of alk so, ... this could explain the test kit situation, indeed.
the first time I tested the calcium hydroxide, my alk was indeed low, I was scared it would raise up a lot.
but on my second test my alk was where it was supposed to be. but didn't notice alk increasing with Kalk (which could be the consumption rate like you mentioned)
It's a AIO aquarium, no hood (mesh net), old habit to have all my tank in contact with air (exchange).
it's on autopilot, I don't touch it much honestly.
(let's not talk about hair algae ... ph ahem, atchoum.)
