The “Water Conditioners & Tank Startup” section gathers essential products to safely prepare tap water and launch a new aquarium. Water conditioners instantly neutralize chlorine, chloramines and heavy metals, making tap water safe for fish, shrimp, snails and plants. Starter kits or bacterial boosters then help quickly establish the biological cycle, enabling the breakdown of ammonia and nitrites — a critical step to avoid toxic spikes when first filling the tank. This dual approach ensures a smooth, stable and healthy start for your aquarium inhabitants.
