This is awesome! Will you be sharing your Files? Also what PH probe is that? I've had a card time finding one to tie into HA that isn't expensive

Yes, but before I'll share, I need to fix some issues in 3D models that I found out after assembly.
When the ESP32 firmware is ready, it will all be in the GitHub repository.

About the PH probe: I'm currently using these Aliexpress "Rechargeable" PH probes.
Its refilling with KCl, so has zero harm for corals, and its and so far values have been very stable for 1+ years.

Only one thing should be considered: it should be placed somewhere where the water level is not rising.
Because the refilling hole should be opened for operation. I'm using a check valve for my return pump, and it's not an issue in my tank.

Amazing project, and very cool that you made a custom PCB for that. Maybe I also should

But for me, I like when everything is standalone and with wifi, so I'm not limited to one closed system and its more fail-safe.
