Review on Tetra Fish Tank Pump Replacement Filter - 3 Pack Large Size, Effective Filtration by Rachel Brennan

Filters are fine. But the product does not match the description. I bought this particular item not only because it was a replacement fill for the holders I have and it contained the 'Timestrip Cartridge Replacement Indicators' that my filter uses and I love having the indicators. They were a bit more expensive but I paid extra to add indicators. BUT the packages I received (I ordered 2) were not as shown here and the indicators were NOT included in what I received.
