Good afternoon.
1 thing deserves your attention
Alkalinity has been gradually declining this week.
MyReefClub brings it all together
Everything happening in your aquarium, together in one place — creating a living history that becomes more useful the longer you keep it.
Tank Memory
MyReefClub remembers it — every parameter logged, every livestock addition, every water change, every milestone.
A year of history tells a story no spreadsheet can. The longer it grows, the more MyReefClub understands your tank.

Everything logged. Intelligence growing.
Tank Intelligence
Logging tells you what happened. MyReefClub helps you understand what's changing — and what that might mean for your tank.

MyReefClub noticed
Alkalinity · Last 8 days
Alkalinity declining over 8 days
Your alkalinity has decreased from 8.7 to 8.0 dKH. At this rate it may fall outside the safe range within a few days — worth retesting before making adjustments.
Based on your last 4 readings
The same intelligence is available to ask directly.
Why are my zoas closed?
I noticed one change worth investigating. Your salinity dropped from 1.025 to 1.023 around the time your zoas began closing. I can't confirm that's the cause, but it's the most notable recent change in your history.
Your NO₃ also moved from 5 to 7 ppm — a relatively small change. I'd retest salinity first before looking further.

MyReefClub does.
Because MyReefClub holds your full tank history, every answer is informed by your actual data — not just the question you asked.
Point your camera at any test kit or digital meter. MyReefClub reads the result, identifies the parameter, and pre-fills the log.
You confirm. One tap. Done.
And if the reading is unusually different from your last — MyReefClub flags it before you log.
