ReefDrift: Reef Parameter Log

Log every reef parameter in seconds. ReefDrift calculates a Tank Stability Score — Stable, Watch, or Danger — the instant you save a reading. Catch a 0.3 dKH swing before it costs $500 in coral. No account. No cloud. Just your tank data, on your device.

LOG THE BIG THREE AND EVERYTHING ELSE

Alkalinity (dKH), Calcium, Magnesium — the parameters reef keepers obsess over. Plus Nitrate, Phosphate, pH, Salinity, Temperature, Ammonia, and Nitrite. Last values pre-fill automatically so a full test set takes under ten seconds, not one screen per parameter.

TANK STABILITY SCORE

ReefDrift calculates a Stable, Watch, or Danger score the instant you save a reading. The score weights every parameter against your target band and flags drift between sessions. A single alk swing from 8.4 to 7.1 dKH registers as Danger before you wonder why a frag is pale. Out-of-range chips light up on the dashboard immediately — no digging, no scrolling.

DOSING CALCULATOR — WIRED TO YOUR TANK

BRS 2-part, ESV B-Ionic, Red Sea Foundation, Aquaforest KH Coralline, and custom products. Enter tank volume and current reading; ReefDrift gives you the exact dose to hit your target. Works for alk, cal, mag, NO3, and PO4. The math uses your real tank volume, not a generic estimate.

TREND CHARTS WITH TARGET-RANGE BANDS

Every reading plotted on a line chart with your target band overlaid. See whether alkalinity is riding the top of the band, drifting toward the floor, or cycling after a large dose. Adjust the time window from 7 days to 12 months.

MAINTENANCE LOG

Record water changes, GFO swaps, ATO top-offs, carbon additions, and frag-tank moves. Cross-reference maintenance events against parameter charts to see what actually moved the needle.

TEST REMINDERS

Set a reminder per parameter or per task. ReefDrift sends a local notification on schedule — no server required. Never miss a Friday alk test again.

HOME SCREEN WIDGET

Your last three parameters and next task on your iPhone home screen or lock screen. See your tank status without opening the app.

BUILT BY REEF HOBBYISTS

We run SPS-dominant systems. We have watched a two-week alk drift destroy a $2,000 Acropora collection. We built ReefDrift because every existing option was either abandoned, clunky, cloud-first, or a bloated social network with a parameter logger bolted on.

ReefDrift is ruthlessly focused: fast log, ho
