Is Driftwood Good for a Fish Tank, and What Does It Do?
Many add driftwood only for looks, but it does more than decorate. This article covers the pros and cons so you can decide whether to use it.
How Can I Make My Fish Tank Water Clear?
Clarify tank water by pre-conditioning new water, doing weekly partial water changes, using a suitable filter, avoiding overfeeding, and planting aquatic plants to absorb nutrients.
How do you change water in a large fish tank?
Changing water in a large tank: prepare dechlorinated water rested three days, turn off the pump, clean the glass, and siphon out bottom waste. Refill slowly along the glass.
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.
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 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.
