Choosing the Right Temperature Control Gear for Your Aquarium:
Aquarium Heaters:
We offer a variety of heaters ranging from simple glass units to durable titanium models with external controllers. Ideal for maintaining consistent temperatures in reef tanks, many of these heaters include built-in safety features like auto shutoff and overheat protection. Whether you're running a nano tank or a large SPS system, there's a reliable option to match your volume and wattage needs.
Aquarium Chillers:
Chillers are essential for reef tanks exposed to high ambient temperatures, intense lighting, or enclosed cabinets. Available in multiple horsepower ratings, they help prevent temperature spikes by actively cooling the water. Most units integrate with external controllers or Apex/Hydros systems for hands-free regulation and can be plumbed inline with sump systems or return pumps.
Digital Thermometers:
Accurate temperature readings are a must. Digital thermometers offer a quick and clear way to monitor water temperature at a glance. Choose from stick-on, probe-based, or wireless models — many with high/low alarms for extra peace of mind.
Optimizing Temperature Control Performance
Size Heaters Based on System Needs:
Select a heater that aligns with your tank’s total water volume and typical ambient temperature range. Larger systems or tanks in cooler environments may require higher wattage or dual heater setups to maintain stability.
Use a Reliable External Controller:
Pairing your heater or chiller with an external controller improves accuracy and adds a layer of protection. Many reefers integrate temperature control into their Hydros or Apex system for precise automation and safety cutoffs.
Avoid Placement Near Flow Outlets:
Install heaters in areas with steady but indirect flow, such as a sump return chamber. This helps distribute heat evenly and ensures the temperature sensor reflects the tank’s actual average temperature.
Monitor Ambient Room Conditions:
Lighting, cabinet ventilation, and room temperature can all influence tank heat. Chillers may be necessary in warmer climates, enclosed stands, or setups with powerful LEDs that raise water temperature over time.
Use Dual Temperature Sensors for Accuracy:
Running two probes in different sections of your system adds redundancy and helps verify accuracy. It’s a simple way to catch discrepancies and fine-tune your automation setup.
Expert Tips
Use Two Smaller Heaters Instead of One Large Unit
If a heater fails, a dual-heater setup reduces the risk of major temperature swings. Each heater can run at half the required wattage, providing redundancy and more stable heating control.
Calibrate and Verify Thermometers Periodically
Even digital thermometers can drift over time. Compare readings across two devices or check against your controller’s probe to ensure accurate monitoring. Replace any unit that consistently reads out of range.
Place Chillers in Well-Ventilated Areas
Chillers produce heat as they operate. Install them in an open, ventilated space—preferably outside the cabinet—to ensure efficient performance and prevent overheating.
Set Your Controller with a Temperature Buffer
Avoid rapid on/off cycling by setting a small temperature buffer (e.g., 0.5–1°F or 0.3–0.5°C). This helps reduce wear on heating and cooling equipment and prevents unstable fluctuations.
Keep Backup Heating or Cooling Equipment on Hand
Temperature is one of the most critical parameters in reef keeping. Having a backup heater or fan ready can be a tank-saver in the event of equipment failure or power outage.
Installation & Maintenance
Installing Your Temperature Equipment
Heaters:
Install heaters in areas of consistent water movement, such as a sump chamber or near a return pump in the display tank. Submersible heaters should always be fully underwater, and placed horizontally or at a slight angle for best heat distribution. Use secure mounting brackets or suction cups to avoid shifting.
Chillers:
Chillers are typically plumbed inline with a return pump or dedicated feed line. Place them in a well-ventilated area outside the stand to prevent heat buildup. Ensure the flow rate matches manufacturer recommendations and use unions or quick-disconnects to make maintenance easier.
Thermometers:
Position digital probe thermometers away from heaters or direct lighting to avoid skewed readings. Stick-on or wireless models should be mounted at eye level for easy visibility and checked regularly for battery life or sensor drift.
Routine Maintenance Tips
- Wipe Down Equipment: Salt creep and dust can accumulate on heaters, cables, and chiller vents. Wipe surfaces monthly with a dry cloth and inspect for corrosion or damage.
- Clean Chiller Coils and Intake Screens: If your chiller has a fan or air intake, clean it regularly to maintain airflow and prevent overheating.
- Test for Heater Accuracy: Compare readings across multiple devices (digital thermometer, controller probe, etc.) to confirm consistency. Replace any heater that shows erratic behavior or fails to maintain target temperature.
- Replace Batteries as Needed: For digital thermometers or temperature monitors, check battery life every few months to ensure your readings remain visible and reliable.
- Inspect Mounting Hardware: Re-seat suction cups, brackets, and clips as needed. Equipment that slips out of place can lead to incorrect readings or inefficient heating/cooling.
