Description

Maintaining a comfortable temperature of approximately 26°C/78°F for your beloved fish The thermometer lets you check the water temperature at a glance, giving you total peace of mind We've made routine care simple. The only regular task? Just remember to rinse the filter sponge weekly for optimal performance. This tool makes water changes easy and effectively removes debris from the aquarium floor and filtration sump Open the pump and check the impeller and shaft for debris. Clean them thoroughly to remove any blockages To prevent excessive algae growth, please avoid high-intensity lighting while maintaining daily illumination for 3-6 hours. The use of a timer for automatic control is recommended Why is my new water pump completely dead with no reaction or vibration? The internal rotor may be stuck at a "balance point". Just give it a firm shake, or remove, clean, and reinsert it to get it working perfectly! For removal, please refer to the "Water Pump Troubleshooting" video in the product description What if the pump, light, or other accessories stop working? Do I have to replace the whole tank? Not at all! We stock all individual parts. If any accessory (light, pump, heater, etc.) is defective, just let us know. We will ship a Free Replacement to you immediately. No need to return the broken part! How to use the fish tank thermometer strip? Simply peel off the backing and stick the strip to the front of your tank, below the water level. Wait 2-5 minutes, then check the color to read the exact temperature I'm worried my small fish might get stuck against the intake vents Designed for safety: The intake slots are ultra-fine (2mm / 0.08") to prevent trapping. Plus, the pump flow is adjustable—simply set it to the lowest speed to ensure a gentle environment for small fish.
