About This Section

These are open-box, overstock, and discontinued products offered below their usual price. The lineup shifts as pieces sell and fresh markdowns are added, so no two visits look alike — checking in often is the best way to catch something you need.

Before You Order

  • One-off stock — quantities are limited and often single-unit, so an item can sell out at any time.
  • Condition noted — open-box and display pieces have any cosmetic details described on their listings.
  • Anything can appear — markdowns span the full catalog, from inexpensive add-ons to premium equipment.
  • No rain checks — clearance pricing applies while supplies last and isn't restocked.

Every clearance item carries the same support as a full-price purchase. If a listing catches your eye, act while it's live — these prices disappear when the stock does. Questions about condition? Email info@jlaquatics.com.

J&L Aquatics was formed in December 1997

Our business was started from our love of the aquarium hobby. We at J&L Aquatics felt that the Canadian aquarist should have the option to purchase top quality supplies, equipment and livestock other than the generally over priced local retail stores.
