How do I add oxygen to a goldfish tank?
Change 1/4–1/3 water weekly, install an air pump/airstone, add live plants for photosynthesis, and avoid overstocking.
What happens if fish tank water is too alkaline?
Over-alkaline water (pH above 7.5) harms fish: it blocks mineral absorption, corrodes skin and gills causing swelling, ulcers, and gill rot, and raises toxic ammonia as pH climbs, risking mass death.
What happens if a saltwater tank is not changed?
Without water changes, rotting food and waste breed harmful germs and raise ammonia and nitrite to lethal levels. Decomposition also consumes oxygen and can kill livestock.
Why is a guppy lying at the bottom of the tank?
A guppy lying at the bottom can be from environment change, poor water or temperature, or health issues. It may be stressed by big water changes or new decor, or by wrong temperature and bad water, or by disease like white spot or saprolegniasis.
Why did my fish tank water turn green?
Green water is usually from excessive algae growth caused by long lighting, excess nutrients, poor water, or lack of filtration. Long light without shade lets algae grow, and high nutrients stimulate it.
Why does my guppy keep jumping out of the tank?
Guppies jump from low oxygen, big water changes, or being attacked. Crowding lowers oxygen, so aerate the tank. Poor water adaptation or tank bullying also triggers jumping.
Why does fish tank water turn yellow
Yellow tank water comes from brown algae, driftwood, long gaps between water changes, or certain feeds and medications. Identify and address the specific cause.
What should I pay attention to when changing fish tank water
When changing water avoid large changes, big temperature swings, direct tap water, and too-frequent changes; add a little salt and dechlorinate new water first. Change 1/4 to 1/3 each time.
How do I add yeast to a fish tank?
Dissolve yeast in 30°C warm water with a little sugar, seal 1-2 days at room temp until active with surface bubbles, then pour slowly in. Water gets cloudy briefly—normal. Over time it improves. Don't use any bactericide, to avoid killing the yeast and its bio-balance.
What aquatic plants should I grow in a fish tank?
Make sure the tank size suits planting and pick species that match your water, temperature, and light. Use 1-2 cm of substrate, plant cleaned roots into it, and provide enough light, CO2, and fertilizer.
