Zoo Med PMC-11 Blue Mechanical Sponge Replacement 3 Pk For 318 TC-20 and 304 MC-10 Review

Average Reviews:

(More customer reviews)These sponges would be better if the filter they are designed for also had an encasement for scuttes. They stop absorbing as soon as they come in contact with scuttes. They can be rinsed out during half tank changes though. So I give them a practical and hardy use 3.
