Learn how to properly cycle an aquarium filter before adding fish — a quick, step-by-step trust-builder for healthy tanks in just 2 minutes. This video covers fishless cycling, establishing beneficial bacteria, monitoring ammonia.

While leaves in your local forest are unlikely to have come into contact with any herbicides or weed killers, leaves collected in your local park or gardens may well have done. Herbicides can be acutely toxic to aquarium fish, which will exhibit signs of poisoning within minutes.

Ammonia build-up in ponds is a silent killer that can devastate fish populations and destabilize your entire aquatic ecosystem. Whether you're managing a koi pond, wildlife pond, or ornamental water garden, tackling ammonia in a pond is critical.

It can be highly rewarding when your fish start to have babies or lay eggs. The sight of lots of happy and healthy fish fry populating your aquarium can bring a lot of satisfaction and joy, but it can also have its pitfalls.
