## What is ReefBuddy?

**Stop guessing. Start thriving.**

Your reef tank deserves better than guesswork. ReefBuddy uses advanced AI to analyze your water chemistry and deliver instant, expert-level recommendations—so you can focus on what matters: watching your corals grow.

** AI-Powered Analysis**
Enter your water parameters and get instant analysis powered by AI. Know exactly what your tank needs, when it needs it, and how much to dose. No more forum diving or conflicting advice.

** Track Everything**
Monitor pH, alkalinity, calcium, magnesium, nitrate, phosphate, and more. Track trends over time. See exactly how your parameters change and catch issues before they become problems.

** Smart Recommendations**
Get personalized dosing advice based on your tank's specific needs. Our AI considers your tank volume, current parameters, and target ranges to suggest precise adjustments.

** Livestock Management**
Track your corals, fish, and invertebrates. Log health events, monitor growth, and keep detailed records of your reef's inhabitants.

** Historical Insights**
Visualize parameter trends with brutalist-style charts. Spot patterns, identify correlations, and make data-driven decisions about your reef's care.

** Smart Alerts**
Set custom thresholds for any parameter. Get notified when values drift outside your target ranges—before your corals notice.

** Bold Design**
A high-contrast, New Brutalist interface that's as beautiful as it is functional. No clutter. No confusion. Just the information you need, when you need it.

**Start with 3 free analyses.** Then unlock unlimited insights with affordable credit packs.
