It sounds like your aquarium has a sludge and dirt build up

How to be sure

Your aquarium has blobs of mud-like matter on the base, on plants and ornaments. This often clumps up in the corners and around objects, it is unsightly and can encourage disease – so it’s time to get cleaning.

Step 1 – Treat your aquarium

  • Treat your aquarium with Sludge Buster. You can check how much you need to dose here.
  • Clean your aquarium substrate using a Gravel Cleaner – this will help remove sludge at the bottom of your aquarium.
  • Use Keep it Clean tablets ongoing to help keep your aquarium in tip top condition and prevent further sludge build ups.

Step 2 – Support your fish

  • Use Aquilibrium First Aid Salt – to help your fish feel well, while your water quality improves.
  • If your fish are gasping at the surface, increase oxygen levels by adding an air pump.
