according to the product map not available in MX. Did you check the homedepot.com.mx site?

What shows online or not is not always available at the store level. That is why I asked.

Never heard of this until your post and now am lusting after it.  If you find it locally, please let us know.  If not, this might help, 
There is a product called "Wet & Forget" which uses this stuff as the active ingredient and it works extremely well  The downside is that it costs anywhere from $30 to $60 per gallon 

A cheaper and DIY method is to purchase HTH Algae Guard from Walmart or Ace Hardware {probably other places too} for between $5 and $10 per gallon {usually around $7} There are different varieties but they are aglaecides meant for pool treatments and this HTH product contains 10% benzalkonium chloride  exactly like the "Wet & Forget" so you dilute in exactly the same way 5 to 1 or basically you make a 2% solution for application.

To round off the mixture I add 1 or 2 ounces of Fabuloso to each gallon diluted for application. The fabuloso is a surfactant like soap but doesn't need to be rinsed off.

The trick for applying this stuff is choosing a cool humid but not raining time where you can saturate the treated areas and the molds/algae/etc. can absorb the chemicals ... so cool evenings are ideal or early mornings where the liquid wont dry too quickly. Ideally you want a few hours of dampness.

So if you want to make yer own just remember you want to generate a 2% solution and add some type of non-residue leaving surfactant ... this is a wetting agent so that the chemicals can spread and penetrate. If you don't mind forking out a little extra money then by all means go for the "Wet & Forget" ... it's a good product
