How to Choose

What to Look For

Prioritize compatibility first: tank volume, filtration capacity, and mounting options must align with your setup. Buy a test kit and use it weekly during the first month—ammonia and nitrite spikes are easier to fix early. For equipment, favor serviceable designs with available media and parts; for livestock, quarantine when possible and acclimate slowly. Finally, budget for ongoing costs (filter media, electricity) not just the purchase price.
