Pronetcus Algae Scraper with 10 Stainless Blades

The Pronetcus Algae Scraper is a blade-style cleaner for glass aquariums. It measures 16.15 Inch long and comes with 10 stainless steel blades, 11 pieces in all. It suits both saltwater and freshwater tanks.

Why a blade

Sponges and pads handle soft film, but green spot algae and coralline growth bond tightly to glass. A sharp blade shaves them off in a few strokes. The large head covers more glass per pass, which makes a full clean quicker.

Replaceable blades

Blades dull over time, especially in reef tanks with coralline. Pronetcus makes them easy to install and swap, and 10 come in the box, so a fresh edge is always on hand.

Safety cover

A plastic blade cover fits over the head for storage. Keep it on whenever the scraper is out of the tank, both to protect fingers and to keep the edge from nicking.

Using a blade on glass

• Hold the blade at a shallow angle and use short strokes.
• Stay clear of the silicone seams, which a blade can cut.
• Do not scrape down into the sand; trapped grains can scratch.
• Use on glass only; blades will gouge acrylic.

Pick the right length

Pronetcus advises choosing a scraper length to match your tank height. The 16.15 Inch size suits common tanks of standard depth. Very tall tanks need a longer model.

Who it suits

Reef keepers fighting coralline on the glass and freshwater keepers with stubborn spot algae. For everyday film, a softer tool like the API algae scraper is quicker and safer to use daily.

Rinse the blade and head in fresh water after each use, dry them, and replace the cover. Salt left on the blade will cause it to dull and corrode faster, even on stainless steel. Change to a fresh blade once you find yourself pressing harder than usual.
