Choose the right formula or accessory

Match each product to your freshwater, marine, reef, planted aquarium or pond setup. Tap-water conditioners, bacterial additives, plant nutrients and mineral buffers have different purposes. Use water test results and the current product instructions to guide your choice, rather than assuming one formula replaces another.

Compare complete plant-care formulas with individual nutrient supplements and root tabs. Flourish Excel is an organic carbon product, not the same product as a general nutrient fertiliser or pressurised CO2 equipment. Check plant and livestock precautions before use.

For Tidal replacement parts, select the exact filter model and pack type. Check media requirements, flow guidance, bag mesh and regeneration instructions where applicable. Match CO2 glassware to the specified tubing or connection size.

Check instructions and purchasing details

Follow the current label for dosage, application and compatibility with your livestock. Reef Dip has a separate application from products dosed into aquarium water. Exterior aquarium cleaners should be used only as directed, not added to tank water.

Check individual listings for pack sizes, retail or OEM packaging, special-order availability and clearance notes. Selected heavy substrates and bulk media carry additional delivery costs.
