Compare gear side by side
Pick up to four products from one category and choose the size of each. Every spec lines up in one table, so the differences are obvious.

How the comparison works
Every column is one product, and every row is one spec, so you read across to see which is bigger, stronger or more efficient. Products with several sizes get a model picker at the top of their column: choose the size you would actually buy and the numbers update.
A dash means the maker doesn’t publish that figure, not that it is zero. Filter and pump flow is the rated figure, measured without media or hoses, so compare filters against each other rather than against your tank’s exact needs. The category pages have a tank-size matcher that allows for that.
Not sure what to compare yet? Start with the kit finder, pick your tank size, and it will list the filters, lights and heaters that fit.

Frequently asked questions
Quick answers about using the comparison table.
How many products can I compare at once?
Up to four, all from the same category, so every row in the table measures the same thing.
How do I compare different sizes of the same product?
Each column with several sizes has a model picker. Choose the size you would buy and the specs update. You can also add the same product line twice if the maker sells it as separate products.
Why is there a dash in some cells?
A dash means the maker does not publish that figure. It does not mean zero, so check the product page or ask the retailer if that spec matters to you.
Is the rated filter flow what I will actually get?
No. Rated flow is measured with an empty filter and no hoses. With media, hoses and height to the tank, real flow is often 30 to 50 percent lower, so compare filters against each other and use the category matcher for your tank size.
