Essential Reef Tank Equipment

Building a reef tank requires more than just a glass box and some saltwater. This guide covers all the essential equipment you need, from absolute necessities to nice-to-haves.

The Tank & Stand

Display Tank

• Glass vs Acrylic: Glass scratches less, acrylic is lighter and stronger
• Rimless: Modern look, requires careful water level management
• Drilled vs HOB: Drilled tanks with sumps are preferred for reefs
• Size: Bigger is generally better for stability

Stand

• Must support 10+ lbs per gallon of water
• Waterproof or water-resistant materials
• Space for sump and equipment
• Level surface is critical

Filtration System

Sump

The sump is the heart of your filtration. Benefits include:

• Houses equipment out of sight
• Increases water volume
• Provides space for refugium
• Easy access for maintenance

Protein Skimmer

Removes organic waste before it breaks down. Essential for any reef.

Sizing: 2-3x your tank volume for best results Types: In-sump, hang-on-back, external Popular brands: Reef Octopus, Nyos, Bubble Magus

Filter Media

• Carbon: Removes yellowing compounds and toxins
• GFO: Phosphate removal
• Filter socks/roller mat: Mechanical filtration

Water Movement

Return Pump

Moves water from sump to display.

• DC pumps: Adjustable, quiet, controllable
• AC pumps: Reliable, powerful, less expensive
• Size: 5-10x tank volume turnover per hour

Powerheads/Wave Makers

Create flow for coral health.

• Target: 20-40x tank volume turnover
• Placement: Create varied, random flow
• Popular brands: Ecotech VorTech, Maxspect, Tunze

Lighting

Modern reef lighting is dominated by LEDs.

Key Features to Look For

• Full spectrum with UV and violet
• Programmable sunrise/sunset
• Adjustable intensity
• Spread pattern for your tank size

Popular Options

| Budget | Mid-Range | High-End | |--------|-----------|----------| | Viparspectra | AI Prime | AI Hydra | | Hipargero | Kessil A80 | Kessil A500 | | NICREW | Red Sea ReefLED | Ecotech Radion |

PAR Levels

• Soft corals: 50-150 PAR
• LPS corals: 100-200 PAR
• SPS corals: 200-400+ PAR

Heating & Cooling

Heaters

• Wattage: 3-5 watts per gallon
• Redundancy: Use 2 smaller heaters
• Placement: Near flow for even distribution
• Quality matters: Cheap heaters fail

Chillers (if needed)

• Required in warm climates
• Size based on tank volume and ambient temp
• Expensive but necessary in some regions
• Consider fans as budget alternative

Testing Equipment

Essential Tests

• Salinity (refractometer)
• Temperature (digital thermometer)
• Ammonia, Nitrite, Nitrate
• pH, Alkalinity, Calcium, Magnesium
• Phosphate

Test Kit Recommendations

| Type | Budget | Recommended | |------|--------|-------------| | All-in-one | API | Red Sea, Salifert | | Alk/Cal/Mag | - | Hanna Checkers | | Refractometer | Generic | Milwaukee |

Automation

Auto Top-Off (ATO)

Automatically replaces evaporated water.

• Prevents salinity swings
• Essential for stability
• Budget to premium options available

Controllers

The brain of your system.

• Monitors all parameters
• Controls equipment
• Sends alerts
• Popular: Neptune Apex, GHL Profilux

Dosing Pumps

Automatically dose supplements.

• Two-part (alk/calcium)
• Trace elements
• Saves time and increases consistency

Water Preparation

RO/DI System

Produces pure water for mixing and top-off.

• Removes chlorine, chloramine, TDS
• Essential for success
• 4-7 stage systems recommended
• Monitor TDS and replace filters

Mixing Station

• Dedicated container for saltwater
• Heater and pump for mixing
• Mix 24-48 hours before use
• Store ready-to-use saltwater

Nice-to-Haves

Quarantine Tank

• 10-20 gallons is sufficient
• Separate heater and filter
• PVC fittings for hiding spots
• Saves your display tank from disease

Refugium Lighting

• Grows chaetomorpha or caulerpa
• Natural nutrient export
• Increases pod population

Backup Power

• Battery backup for return pump
• Generator for extended outages
• Air pump as minimum backup

Equipment Priority Order

If building on a budget, prioritize in this order:

1. Quality tank and stand
2. Heater (reliable brand)
3. Lighting (appropriate for your corals)
4. Circulation (return pump + powerheads)
5. Protein skimmer
6. ATO system
7. Test kits
8. Controller

Tracking Your Equipment

Keep records of:

• Purchase dates
• Warranty information
• Maintenance schedules
• Replacement parts

AQUAXONE's equipment tracking feature helps you stay organized and never miss a filter change or warranty expiration.

Conclusion
