All depletion on a “new tank” with no corals

[Faulkner’s maze]

So I have a new tank up after my previous one. Running a Red Sea 350 with 63 system water. Had up to today 2 fish (now 5 today) -No corals.

anyway I had the LFS run a parameter check. Mg on the higher side (1400 but ok),, CA was in normal range, but the ALK was at 5 dkh-little surprised by this.
Only thing running is a biopellet reactor running-but I don’t think this would cause an alk drop.

Looking for other reasons why this might occur Thanks

Could be precipitation happening?
Also corals are not the only thing that can change alk...

I suppose but I don’t know enough about what would prompt it. With no corals-it does lead to other suspects-just don’t what they are

Have you tested your freshly mixed water? Could be test error, bad batch of salt, etc. Worth checking I suppose.

I got the sw from the LFS so I hope that’s not an issue -but that thought occurred to me. Unfortunately I can’t find my alk meter. I know what I am getting this weekend

Keep in mind anything that produces acids, including the cycling process and fish waste, will lower alkalinity. I doubt that would make a huge difference, but possibly that in addition to the the water you got not having very high alk to begin with. Could be their test results weren't completely accurate too.

Thanks-I need to check the water again. Just annoyed I can’t find my alk meter. It is entirely possible all those things are true…

Cycle and the entire process consumes alk. It's normal to have a drop when starting.

Never knew that. Thanks!
