AmGuard™ safely, rapidly and efficiently detoxifies toxic free ammonia. It is safe to use during tank cycling and is ideal for treating emergency situations. AmGuard™ is the strongest liquid ammonia binder on the market. It works within minutes to detoxify free ammonia, and it doesn’t degrade for nearly 72 hours. That’s at least twice as long as our competitors’ products. Unlike competing products, AmGuard™ converts it into a safe, non-toxic form that is readily removed by the tank’s biofilter. It does not alter pH.

Ammonia can exist in two forms: free and ionized. It is only the free form that is toxic. Traditional ammonia test kits convert all ammonia to free ammonia by raising pH to 12–14; at this pH AmGuard™ cannot function and thus a false positive reading will result. 

  • Detoxifies ammonia for up to 72 hours
  • Ideal for emergency situations
  • More effective than any other ammonia-binding product
  • Most concentrated product on the market

Petland ships orders Monday through Friday (excluding statutory holidays).  We use Canada Post, Purolator & Canpar for delivery.  "Free Shipping" will usually be sent through Canpar Ground service.  Canpar Ground & Purolator Ground services do not have guaranteed delivery times and the shipping times will only be estimates.  

Orders made online after at 11 AM CST on Fridays will ship the following business week.  When considering delivery times after an order is placed, please allow 1-3 business days to process your order. Courier delivery times do not include the day the order has been picked up from our warehouse. 

Orders that include "special order" items will not be shipped until the "special order" item arrives in our warehouse.

Please provide a street address if you choose "Free Shipping", Canpar or Purolator as your shipping method. 

  • If you have a PO Box, Rural Range Road, Township Road or Site land location address, you must choose Canada Post as your shipping method.

Both Canpar and Purolator shipments will require a signature upon delivery unless you have requested the shipment to be left at your front door with "no signature required". **  If you do not make this request and are not home to receive your order, an attempted delivery notice will be left at your front door.  The notice will indicate the depot where you can pick up your shipment.

**Please note that neither Petland nor the delivery service is liable for any lost or stolen packages if you have requested the shipment to be left at your front door.

Undeliverable packages:

Occasionally, we will have a package returned to us because it was undeliverable. When this occurs, we will issue a full refund for the price of the product plus taxes. Shipping charges are non-refundable.  If your order had "Free Shipping" the shipping charges incurred by Petland for your order will be deducted from the total product refund amount.

We can receive packages as undeliverable for the following reasons:

  • Missing house number, unit number or buzzer number
