7 Beginner Coral Mistakes That Cause Early Tank Losses

Avoid the most common beginner coral mistakes with this practical checklist for placement, flow, lighting, and stable reef parameters.

Most beginner coral losses come from instability, not bad luck. Here are the biggest mistakes to avoid.

1) Adding coral too early

Wait until your cycle is complete and parameters are stable for at least a couple weeks.

2) Skipping acclimation

Drip and light acclimation reduce shock. Start lower in the tank and move up gradually.

3) Too much light too fast

High PAR can bleach new frags quickly. Ramp intensity instead of jumping to final settings.

4) Ignoring flow patterns

Dead spots trap waste; direct blast can damage tissue. Aim for indirect, variable flow.

5) Chasing numbers daily

Consistency beats constant adjustment. Track trends and make small corrections.

6) Overstocking early

Add coral slowly so nutrient demand and bacterial load can adapt.

7) Not testing key parameters

Keep salinity, alkalinity, nitrate, and phosphate in check. Log readings in the ReefBay app.
