✅ Test Weekly: Monitor pH, ammonia, nitrites, and nitrates.
🌡️ Temperature Control: Keep discus tanks at 82-86°F (28-30°C) for tropical species.
🔄 Water Changes: Replace 20-30% weekly to remove toxins.
🧪 Use Conditioners: Neutralize chlorine and heavy metals.
Pro Tip: Invest in a liquid test kit – it’s more accurate than strips!

Recognize Your Fish’s Needs
Understanding species-specific requirements is key to a thriving aquarium. Discus, for example, demand stable temperatures (82-86°F) and soft, acidic water, while hardy species like tetras adapt to broader ranges. Always research your fish’s natural habitat and behavior before introducing them to a community tank. For sensitive species, use Seachem Prime to detoxify tap water and API Aquarium Test Kits to monitor pH, ammonia, and nitrates.
Chlorine and chemicals
Maintaining pristine water conditions is critical for aquatic life. Tap water often contains chlorine, chloramines, and heavy metals that stress fish and disrupt biological filtration. API Tap Water Conditioner is a trusted solution, neutralizing harmful chemicals instantly while supporting slime coat health for fish. For advanced monitoring, pair it with Seachem Prime to detoxify ammonia and nitrites, ensuring a safe environment for sensitive species like discus.
“Not All Fish Thrive in the Same Waters.”
Rule #1 for Aquatic Safety: Never Compromise Water Quality
Fish are entirely dependent on their environment. Leaving tanks unchecked can lead to deadly ammonia spikes or pH crashes.
🔍 Monitor Daily: Use the API Freshwater Master Test Kit to track ammonia, nitrites, and nitrates.
🛡️ Preventative Care: For delicate or aging fish (e.g., long-finned angelfish), stabilize water with Seachem Stability to boost beneficial bacteria.
🌡️ Temperature Control: Sudden fluctuations harm fish. Use the Fluval E300 Heater with digital monitoring for precision.
Pro Tip: Acclimate new fish slowly using the drip method over 1-2 hours. Pair this with API Stress Coat to mimic their natural slime coat and ease transitions.
