AquaClear 20 Activated Carbon Inserts, Aquarium Filter Replacement Media, 3-Pack, A1380

thanks

Works as expected and will purchase again if needed.

It turned my water milky white and left a white film on everything. Rinsing didnt matter. I had to clean my tank multiple times. Horrible product!

My LFS sells these filters for $17.99! My water is crystal and the parameters are great, so I feel they do their job well. Cant beat the price and free shipping with Prime!!

Fish seem to like it!

Larger than the stock bag, but Im not about to complain about that

Great

Works great

As advertised.

The packaging is good...teach bag is sealed and after rinsing with tank water just put in your filter... I have been using these for over a year and I will not switch brands...water remains clear and they seem to last about 2 months
