Glass fish tank algae inhibiting coating for existing/new marine, tropical and cold-water fish tanks.

Creating a permanent finger-wipe removal of algae and greening.

Coverage:  Approx’ 3m²

£ Cost / m²: £8.33 / m²

Durability: 10 year functionality when maintenance instructions are followed. 



The coating is crystal clear, UV stable, chemically inert and extremely durable, having both hydrophobic and oleophobic capabilities. It is unaffected by extremes of temperatures from –20°C to +450°C.

TankGuard™ Performance:

  • Permanent bond that will not peel or flake, preserving the surface quality.
  • Does not reduce light transmission or optical values.
  • Not affected by UV bonding.
  • Resists salt water corrosion.

TankGuard™ Benefits:

  • Can be applied to all glass fish tanks.
  • Environmentally friendly, contains no irritants or HCFCs.
  • Allows finger-wipe removal of contamination.
  • Certified food safe and inert by ISEGR.


For both new and existing fish tanks.

Application Instructions

1.Preparation of glass surface with TankGuard Pre-Clean

Ensure glass is dry, and clear of grease and dirt. Spray the inside glass surface of the dry tank with TankGuard Pre-Clean and rub the product into the glass surface with the pre-cleaning cloth (white). Divide larger tank glass panes into sections for treatment of about 0.5m² to minimise rapid evaporation of the product.

The glass is clean when streak formation is no longer evident. Apply the TankGuard coating immediately after pre-cleaning of the whole glass surface.

  1. Coating with TankGuard

After pre-cleaning, spray TankGuard onto the inside glass surface, ensuring good coverage. Spread the product around the glass surface with the coating cloth (blue) to ensure complete coverage of the surface.

Because of the rapid evaporation of the product, divide larger glass panes into sections for treatment of about 0.5 m². After coating the last section of the glass, polish away the surplus from the glass surface (in one operation) with the coating cloth.

Each 30 ml bottle should cover approx. 3m² of glass.

Use any excess product to treat the outside of your tank to allow easy removal of finger prints and limescale from spilt tank-water

Reaction time, quality control and maintenance Immediately after the application of TankGuard the nano-particles form a strong bond with the glass surface in a chemical reaction.

The TankGuard surface can be handled immediately after coating. Whilst rapid bonding takes place between the coating and the glass, allow 24 hrs at 20°C room temperature before filling tank for the coating to become completely inert. Once filled, your TankGuard coating is in action, immediately inhibiting the adhesion of algae.

Speed of algae growth will be dictated by conditions and content of the fish-tank and the light source.

Algae can be removed quickly and easily by agitation from a soft cleaning implement .Do not use abrasive product on the surface of the glass.

Enjoy the time you’ve saved !
