Searched “why is my coral dying,” “reef tank crash,” or “brown algae bloom saltwater tank”? You already know how scattered the answers online are.

This 26-page guide is built for the first 90 days of reef keeping — the exact window where most beginners lose their first corals or quit entirely.

It’s not another encyclopedia (free videos already do that better). It’s the opposite: a fast, printable reference that answers one question in under a minute — “what’s happening in my tank, and what do I do about it?”

What’s inside:

• Week-by-week roadmap of what’s normal in weeks 1–12
• Real target parameters (alkalinity, calcium, magnesium, nitrate, phosphate) in plain English
• Correct, no-guesswork cycling guide
• The “ugly phase” explained: diatoms, cyano, hair algae, dinoflagellates — ID and fixes
• Coral stocking order + correct acclimation and dipping steps
• A troubleshooting decision tree for the moment something looks wrong
• Testing/dosing discipline that stops you “chasing numbers”
• Printable parameter, dosing, and stocking logs

The core idea: coral responds to stability, not perfect numbers. Most disasters come from panicking and changing five things at once — this teaches you what to leave alone.

Won’t guarantee every coral survives — nothing honestly can. It gives you a real system to improve your odds, and a reference you’ll actually use.
