Test Before You Dose

Adding supplements without testing is how most tanks drift out of balance. A test kit tells you what the water is actually short of, so you dose to a number rather than a hunch — and it's how you catch a stalled cycle or a nitrate creep before livestock show it.

Which Kit for Which Tank

  • New setups — ammonia, nitrite and nitrate, to follow the cycle through to completion.
  • Freshwater and planted — pH, GH and KH for general and carbonate hardness, plus phosphate and nitrate for algae control.
  • Reef and marine — calcium, alkalinity and magnesium as the core three, with nitrate and phosphate for nutrient management.
  • Master kits — several parameters bundled at a lower cost per test than buying individually.
  • Test strips — quick approximate screening; use a liquid kit to confirm anything that looks off.

Reagents have expiry dates and lose accuracy over time, so replace kits that have been on the shelf a while rather than chasing a reading you can't reproduce. Questions? Email sales@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.
