How to Choose

  1. Consider whether you use Neptune Apex hardware - if so, Apex Fusion is a natural fit alongside a manual tracker.
  2. Evaluate how many tanks you maintain - free tiers often limit you to one.
  3. Decide if you need desktop access or if mobile-only works for your routine.
  4. Check whether CSV export matters for your record-keeping workflow.

Frequently Asked Questions

Why should I track reef tank water parameters digitally?

Digital tracking gives you trend charts over weeks and months, making it easier to spot slow drifts in alkalinity or calcium before they harm corals. Paper logs are hard to analyze retroactively.

Does My Reef Log work with automated test equipment?

Currently My Reef Log focuses on manual test entry from any device. Integration with automated testing hardware is on the roadmap.

Can I share my tank data with other hobbyists?

Yes, all plans include public sharing links so you can share your tank's parameters and livestock with the reef community.
