Flourish Potassium™ contains concentrated levels of potassium suitable for sensitive natural planted aquariums. Potassium is one of several elements that are vitally important to maintaining growth in a planted aquarium. Use Flourish Potassium™ to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth. Flourish Potassium™ is unique in the sense that it is derived from potassium sulfate, allowing the user to adjust potassium levels without affecting nitrogen or phosphorus levels.

  • Potassium supplement for planted aquariums
  • Highly concentrated (50,000 mg/L)
  • Will not affect nitrogen or phosphorus levels in the aquarium
  • Ideally for use in delicate planted aquariums

Shipping

Currently, there may be shipping delays in some areas due to inclement weather.

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 Friday at 11 AM CST will ship the following business day.  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.
  • If your address is an apartment or condo, please include the buzzer number.

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
  • Missing street name, City, or province
  • Incorrect Postal Code
  • Failed delivery attempts or the item was not picked up from the local depot within 5-10 business days.
  • Refused by the recipient.
