keep tank clean and safe for Goldie

long lasting and rssy to use

Enjoy using these to help keep my turtle tank clean. It comes in a good quality pack at a good price. Helps to keep the water clean longer.

Great product. Change my filter pads more frequent in the hot summers. Also it's nice to be able to add more charcoal or ammonia chips if needed. My aquariums stay crystal clear and maintaining water conditions.

Great price for a dozen filters, makes it easy to open a pre-measured carbon pouch and pour into filter media. Wish it had 3 plastic frames to allow for preparing additional filters for those days when pressed for time. This a real cost saver and it helps to contain the waste and therefore helps the environment. It is so easy that your pre-teen could prepare and change the filters in just a few minutes. No available in all stores, but always on-line

So, while this does the job, it is rather annoying having to put the thing together myself. I only bought this because the ready to go ones are out of stock. It'll do in a situation like that, but I definitely won't order them again if the others are available.

Arrived with charcoal all over everything else in the box. The product itself is sufficient, did find a filter that wasn't sealed at the bottom making this 1 less in the box. Open to other brands as a replacement.

picked up the package and heard rattling, knew something was wrong right then. opened the box and all the packets of carbon were busted and spilled all in the box. the manfacturer sealed them wrong apparently, but now i cant use these....
