Feeding tip: less is more! 🐟

Overfeeding is one of the most common causes of cloudy water and algae. Feed small amounts that your fish finish in a couple of minutes, and remove anything left over.

A quality complete food like TetraPRO Colour Multi-Crisps gives great nutrition and colour without fouling the water 👍

Beginner guide: choosing aquarium lighting 💡

Good lighting does more than show off your fish. It drives plant growth, coral health and your tank's day and night rhythm.

✅ Freshwater plants: look for a spectrum and intensity suited to what you're growing
✅ Marine/reef: choose a fixture designed for corals
✅ Use a timer, because consistent hours help keep algae in check

Not sure which one fits your tank? Drop us a message and we'll point you the right way! 👍

Pond owners, mind the leaves! 🍂

Fallen leaves look pretty, but as they rot in the pond they release gases and add to your water's waste load, which can harm your koi through winter.

🍁 Net the pond before the leaves drop
🍁 Skim off what lands on the surface
🍁 Keep your pump and filter running

Why every reef needs a protein skimmer 🪸

A skimmer pulls dissolved organics out of the water BEFORE they break down. That means cleaner water, less algae and happier corals!

We stock a great range of skimmers and reactors, from compact to big reef systems 👍

MYTH BUSTER: "Fish only grow to the size of their tank." 😎🐟

Sadly not true! Fish don't stop growing to fit their home. They just end up stunted, stressed and unhealthy in a tank that's too small.

Always research adult size BEFORE you buy. Not sure? Ask the team and we'll help you pick fish that suit your tank 👍

Beginner guide: cycling a new tank 🐠

Set up a shiny new aquarium? Don't rush to add fish! The tank needs time to build the beneficial bacteria that break down fish waste.

✅ Set up, dechlorinate and run the filter
✅ Add a bacteria source or additive and test regularly
✅ Add fish once ammonia and nitrite read zero and you can see nitrate

Patience now means healthy fish later! Questions? Just ask us 👍

Troubleshooting Sunday: green glass and algae 🟢

Before you blame the tank, check the basics:
1️⃣ Cut lighting back to a consistent 6-8 hours and ensure no direct sunlight from the window
2️⃣ Don't overfeed: only what they eat in a couple of minutes
3️⃣ Scrape the glass weekly and keep up with water changes

A good scraper makes the weekly job quick and easy! 👍
