Have Questions About Freshwater Aquarium Maintenance?

We have answers. Get quick help for common questions.

How often should I clean my freshwater aquarium?
Cleaning frequency depends on your tank size, fish load, and filtration setup. Most aquariums benefit from partial water changes and substrate cleaning every 1–2 weeks. Filters should be checked and rinsed monthly, and algae scrapers used as needed to maintain clear glass. Consistent maintenance prevents buildup and keeps your water parameters stable.
Do I need to take the fish out when cleaning?
No—removing fish during cleaning causes stress and may do more harm than good. Use gravel vacuums and siphons carefully to avoid disturbing your fish. Always condition new water before adding it, and match temperature to avoid shocking your livestock.
Can I clean the filter too often?
Yes—over-cleaning or changing all the filter media at once can disrupt beneficial bacteria colonies, which are crucial for biological filtration. Clean sponge or mechanical filters in old tank water to preserve bacteria, and replace chemical media like carbon or resin monthly as needed.
How do I maintain water quality between cleanings?
Avoid overfeeding, stock your tank appropriately, and keep filters running efficiently. Consider using products like liquid bacteria supplements, ammonia detoxifiers, or plant-based filtration to maintain balance between water changes.
What tools do I need for regular tank maintenance?
At minimum, you’ll want a gravel vacuum, an algae scraper or magnetic cleaner, a siphon hose, and water conditioner for topping off or changing water. Test kits, filter media replacements, and buckets dedicated to aquarium use are also essential for thorough maintenance.
What’s the best way to clean aquarium glass?
Use a dedicated algae scraper, magnetic cleaner, or sponge designed for aquarium glass. Avoid household sponges or glass sprays, as they can contain chemicals toxic to fish. Clean the inside glass weekly or as needed to maintain visibility and prevent algae growth.
What causes cloudy water in freshwater aquariums?
Cloudiness can result from overfeeding, bacterial blooms, substrate dust, or insufficient filtration. Test your water parameters and check for uneaten food. Performing a partial water change and using filter floss or polishing pads can help restore clarity.

Good to know

Why are some points pending?

Purchase points have an approval period before they become available. Your balance shows available points separately from pending points.

How long do my points last?

When points expiry applies, your balance stays valid for 365 days from qualifying rewards activity. Earning eligible rewards, redeeming points or a balance adjustment renews that window. Simply visiting the shop does not renew it.

Can I use points with my stamp reward?

Yes. Add your 10% stamp reward code at checkout and switch on your points. Your final saving depends on the eligible product total and any other discount restrictions.

What happens if I return something?

Earned points are adjusted for returns. Points used on refunded products are restored proportionally. If a refund takes a qualifying order below £250, its stamp is removed.
