I have been looking for filters to fit my 6 gallon tank for a long time. Finally I have found filters that work. Thank You


Product was great. Staff was very helpful. But shipment was a little rough. Didn't get product until Friday when order status said Tuesday. And didn't get any info on why order was late.

great product at a great price

recently, my local pet store stopped carrying this item in store. feeling betrayed, i turned to the internet to help my search, expecting to pay more and wait long for shipping. fortunately, valuepetspplies was neither of those! got these babies for half the cost of my store plus free shipping. the package was at my door within 4 days. im very satisfied with the product and the service.

Great filters

If this shipping weren't so high, this would be my go-to place to get all my filters. Such great prices and fast shipping. Thanks!

High shipping cost

I was very happy with the product and the price but the shipping cost was a bit steep for such a small product.

I am very happy with the products and services received

I am very pleased with how fast my slim filters arrived. The convenience of ordering multiple filters at one time was great. I have had a hard time finding these filters in stores so I am very happy with my product and service. Thank you,

I am very happy with the product and service I have received

I am very pleased with how quick my slim filters arrived. It is very convenient to order them online. I have tried to find them in stores with no luck. Thank you

Great filter cartridge

These filter cartridges really keep your aquarium clean. They are good in that you only change one cartridge type at a time in your filter housing.
