How does the aquarium equipment finder work?

Enter your tank size, water type, and livestock to get a filtered list of compatible equipment. The finder matches filters, heaters, lighting, CO2 systems, and substrate to your specific setup — so you're not sorting through products sized for tanks twice as large or half as small.

What tank sizes does the finder cover?

The finder covers tanks from nano setups under 5 gallons through large displays over 100 gallons. Filter results by your exact volume to see products rated for your water column and bioload.

Can I use the finder to replace a broken filter or heater?

Yes. Switch to Replacement mode, enter your current model number or part name, and the finder returns exact matches and compatible alternatives ranked by confidence. It pulls from the same product database as the main search.

Does the finder include saltwater equipment?

Yes. Use the water type filter to narrow results to freshwater, saltwater, or brackish setups. Equipment categories, flow rates, and lighting spectrums are all filterable by water type.

Are the product links up to date?

Product listings are updated regularly from verified sources. Each result links directly to the current Amazon listing so you can check live pricing and availability before buying.
