Your reef tank deserves better than a spreadsheet. This agent tracks all your water parameters — pH, ammonia, nitrite, nitrate, phosphate, calcium, alkalinity, magnesium, salinity, temperature — with trend analysis that tells you exactly how fast your alk is drifting and when it will hit your minimum threshold. Catch parameter crashes before they happen, not after. Built for the 500K+ dedicated US reef keepers who know one parameter swing can wipe out $2,000 in corals overnight. ## What's included - **Parameter logging with trend lines** — pH, NH3, NO2, NO3, PO4, Ca, Alk, Mg, salinity, temp, ORP; per-tank baselines + drift rate per day - **Crash prediction** — current alk dropping 0.3 dKH/day, minimum threshold in 4 days: dose now or schedule water change - **Dosing program tracker** — two-part, kalkwasser, balling, Triton method; auto-calculates daily doses from consumption curves - **Livestock compatibility checker** — before adding anything: aggression, predation risk, reef-safety, swim-zone overlap, size at maturity - **Coral growth + frag log** — month-over-month encrustment, fragmentation events, parent colony lineage, sale prep - **Maintenance schedule** — skimmer cleaning, UV bulb replacement (6-mo cycle), reactor media changes, return pump service - **Water change calculator** — % volume + salinity-matched newwater target; gallons per change at current consumption - **Equipment failure detection** — temperature spike (chiller fail), salinity drift (ATO fail), pH crash (skimmer overflow) - **Tank journal** — water tests, new additions, observed behavior, photos; full history searchable ## Limitations - **Not a controller** — pairs with Apex / GHL / Hydros for actual probe automation; this is the human-side dosing + tracking layer - **Not a livestock vendor** — recommends compatibility; sourcing happens through your LFS / online aquaculture - **Not coral disease diagnosis** — flags patterns (RTN, STN, brown jelly); confirmation needs a reef veterinarian or experienced LFS - **Not water-testing hardware** — you test with Salifert / Hanna / Red Sea kits + log values; doesn't connect to test sensors - **Reef + freshwater scope** — saltwater reef is primary; freshwater planted tanks supported at the parameter level ## Best fit Dedicated reef keepers with 30-300 gallon mixed reefs, SPS-dominant systems, and anyone running an active dosing program. Especially valuable for tanks valued at $1,500+ in livestock where the cost of a parameter crash (RTN'd colony, dead fish) is the difference between a casual hobby and a $5,000 setback. At $12/mo, one caught alk crash pays for the entire tank's monitoring for a decade.
