Life-stage guide
Maintenance routine, stocking changes and long-term water quality.
Nitrate is the end product of your tank's nitrogen cycle, and it slowly climbs between water changes. This guide explains safe target levels for fish and shrimp, the everyday causes of a slow rise, the main methods keepers use to control it, and a calm, step-by-step routine to lower it without shocking your livestock.
A stable aquarium comes from small, regular tasks rather than occasional big clean-ups. This guide breaks maintenance into daily, weekly, monthly and yearly routines for fish and shrimp tanks, compares the main maintenance philosophies, and shows how to protect your beneficial bacteria while keeping water healthy.
Aquarium lights are for your plants and your viewing, not for the fish, which do not need them. This guide covers how many hours to run your lights by tank type, why intensity matters as much as duration, the siesta method, and how the right photoperiod keeps algae down while plants and fish stay healthy.
