    Seachem PhosGuard 250ml

    A chemical filter media made from spherical aluminum oxide, designed to remove unwanted nutrients from aquarium water.

    What it does

    • Removes phosphate (PO₄) → main cause of algae
    • Removes silicate (SiO₂) → helps control brown algae (diatoms)
    • Improves water clarity
    • Does not release absorbed waste back into water

    Key features

    • Spherical beads → better water flow, less clogging
    • Works in both freshwater and marine aquariums
    • Fast acting (works within a few days)
    • High adsorption capacity

    Dosage & usage

    • Use about:
      • 85 ml per 200 L (saltwater)
      • 85 ml per 400 L (freshwater)
    • Place in:
      • Media bag
      • Canister filter / sump / HOB filter
    • Use for about 4 days, then check phosphate level and replace if needed

    When to use it

    • Algae problems
    • High phosphate levels
    • Brown algae (diatoms) outbreaks
    • Overfeeding or high waste tanks

    Important notes

    • Not ideal for phosphate-buffered planted tanks
    • Avoid sudden large drops in phosphate
    • Not reusable (replace when exhausted)
    • Always rinse before use
    Care

    Caring for your clothes is also caring for the environment.

    To keep your clothes fresh and clean, simply refresh them and gently wipe with a cloth or clothing brush. This is a more delicate process for fabrics and helps avoid water and energy consumption from washing.

    • Do not use bleach or brighteners
    • Iron at a temperature not exceeding 110ºC / 230ºF

    Largest collection of tropical fish I've seen

    This shop has the largest collection of tropical fish I've seen. A huge range of discus and cichilids and the staff is very knowledgeable. I'll be back to stock up my tank once its cycled.
