Is it normal for a tank to drop like this? I test before I do the drop of Bio S each night once lights are off. I also noticed that my dKH has been dropping quite quickly for the last three days since I bought a dKH test. Below is my tank details and log for reference, if needed. Planning to get a chunk of live rock next week.
Tank:
20G water box cube
9kg dry rock
live sand
bag of ceramic balls
dosing bio S nightly
ATO from bucket of RO DI water
Log:
26/08/2022
AF Bio sand + two liquid bottles of bacteria cultured as per instructions for 24 hours @ 26C.
25/08/2022
Late evening the live AF Bio Sand sand was added to the tank and the tank was brought to temp (raised from 23C to 25C), lights off, circulation on, only filter media are ceramic rings in the back and 9kg of dry rock.

One drop of Bio S in the evening to feed bacteria.
AI light off, but ambient light present.

Went in to the fish expert today, he was very impressed with the rock work Richard and I made. He said to turn the light on full for 6 hours each day to speed up the ugly phase. He said don't try and skip the ugly phase because the bacteria and small critters will need to eat the matter it produces and it will be better to just speed it up by blasting it and letting it happen. He said come and get a zoa in one week on live rock, to add variety to the bacteria while it's still fighting for dominance. He sold me a dKH test.
