Email only. No form, no auto-responder.
Mail is forwarded through Cloudflare Email Routing to a working reefkeeper, not a support team, so there's no guaranteed reply time. Corrections can also go straight to corrections@reefcalcs.com, the address listed on the corrections log.
What gets a fast response
- Corrections backed by a primary citation. If a number on the site contradicts a Randy Holmes-Farley article, a manufacturer's published PDF, or a peer-reviewed paper, send the link and the page URL. These get fixed first.
- Embed requests from real reef sites. Link to your blog and the page where you want to drop the calculator iframe.
- Bug reports with reproduction steps. "The kalkwasser calc shows 0 when I enter X" — include the inputs, browser, and what you expected.
What gets a slow response
- Tank diagnostic questions. We are not a livestock vet service. Post on Reef2Reef for that.
- Cold pitches to insert affiliate links, sponsored content, or paid placements into existing articles. Editorial decisions are not for sale.
- SEO tools, link-building, or guest-post inquiries. Hard pass.
- Generic outreach ("we'd love to discuss a partnership"). Be specific or be ignored.
For developers
If you want to embed a calculator on your reef blog, the iframe snippet for every calculator is on its individual calculator page, in the "Share / embed this calculator" expander. No email needed for that — just grab the snippet. See terms for the embed rules.
