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.
