Product claims to inhibit algae from growing on surfaces

By Leonard Ho - Posted May 15, 2017 09:00 AM
NanoClear is a new spray-on chemical that claims to impede algae growth on glass and rocks while being safe for aquarium fish and invertebrates.


NanoClear are chemical sprays designed to inhibit algae growth on aquarium surfaces by creating a "firm and smooth molecular layer where no algae or bacteria can attach to."  Currently, there are two versions of the spray offered; one is intended for glass application while the other is intended for stone application.  The chemicals are said to be safe for all aquarium life including invertebrates.

To apply on glass:

  1. Thoroughly clean the aquarium glass with an alcohol-based cleaning agent. Wash off the remaining of the cleaning agent with a good amount of water. Dry the glass .
  2. Wear gloves to avoid recontamination of the surface.
  3. Shake the bottle and evenly spray the glass with the agent.
  4. In 30 minutes remove the remaining liquid and polish the surface with a cotton cloth.
  5. In another 30 minutes you can start aquarium set up.

The manufacturer claims that NanoClear's "fouling protection" is effective for up to two years once applied, as their self-supplied demonstration photo shows.

NanoClear is manufactured and distributed by Collar, a Ukrainian-based international pet product company.  According to Collar, NanoClear was first developed in 2015 and has undergone multiple formulations to create an effective anti-algae coating that is safe for aquariums. There are currently many types of nano-particle spray-on films available (e.g. ceramic coatings) for a range of commercial purposes.  There are even a few competitors to NanoClear that are marketed specifically for aquarium use (mostly in Europe, such as Percenta Nanotechnology), although we've heard surprisingly little reports about their usage.

Advanced Aquarist is unable to verify any of the manufacturer's claims (neither its efficacy nor its aquarium-safe claim), so please try this product at your own discretion; for those who purchased NanoClear or a similar product, we would love to hear your feedback in the comment section below.  The durability of the coating is an especially interesting question mark.  How do these chemicals hold up against grazing animals or magnet cleaners?

Collar recently successfully completed its Kickstarter crowd-sourcing campaign and is scheduled to start shipping its first production run this month (May 2017).  The prices of each bottle (able to treat up to a 150 liter/40 gallon) appear to range form $5 to $9 USD.  Now that the Kickstarter campaign has ended, we're not sure if aquarists can purchase this product directly online.  We suspect that Collar will sell NanoClear via its established distribution channels in the coming months.
