Every change we make to a published page is logged here, with the date and what changed. If you spot an error we haven't fixed, email corrections@reefcalcs.com.

  1. Link

    Fixed three broken internal links to /guides/vinegar-carbon-dosing, /guides/icp-testing-for-reef-tanks, and /calculators/aquarium-sand after those pages were renamed. Updated every reference across the site.

  2. SEO

    Added descriptive og:image:alt text to 4,636 pages so the social-share image is announced to screen readers and link-preview crawlers.

  3. SEO

    Tightened meta titles and descriptions across the site so they render fully in search results instead of being truncated mid-phrase.

  4. Clarity

    Reworded the inch-per-gallon stocking guidance to state plainly, up front, that it is a rough starting heuristic for fish only — not a rule for corals or for sensitive species — because it was being read as more precise than it is.

  5. Factual

    Corrected the magnesium dosing reference: the Recipe 3A magnesium chloride / magnesium sulfate ratio now matches Holmes-Farley's published figures. The earlier version overstated the sulfate share, which would have nudged the magnesium result slightly high.
