Keeping your GloFish® healthy and happy involves regular partial water changes along with proper feeding. Performing partial water changes is essential to maintain a clean and safe environment for your fish. Follow these easy steps to ensure your tank stays in top condition:
Initial Water Changes for New Tanks or New Fish:
Monitor Your GloFish®:
Performing a Partial Water Change:
Step 1: Gather enough bottled water to replace about a third of your tank's volume. If you use tap water, treat it first with AquaSafe® Water Conditioner (included with your order) to remove harmful chemicals like chlorine.
Step 2: Let the treated water sit until it reaches room temperature. Sudden temperature changes can harm your GloFish®.
Step 3: Remove and discard about a third of the old tank water. Do not remove your GloFish® during this process to avoid stressing them.
Step 4: Slowly add the new, treated water to your tank.
If Water Remains Dirty:
By following this guide, you can keep your GloFish® tank clean and your fish healthy. Performing partial water changes regularly is essential for a happy and vibrant aquarium.
