CNZ® Aquarium Filter Media Kits (Double Pack) - Activated Carbon, bio Ball, Ceramic Ring

Horrible results. Like Robert, I followed all the directions, found that the rinse water never really ran totally clear, so went ahead and set up the bag at the waterfall in my 2800 gallon pond. After 2 days, my pond water was totally black, waterfall rocks covered with soot, couldnt see an inch below the surface. Pulled out the bag of carbon and it drizzled black water all over the ground - apparently this is what was pouring into the pond for 2 days. Had to drain and refill the pond and use quilt batting to remove the remaining carbon/soot. I dont dare try this again.

Perfect

I give it a 5 star, just what I was looking for.

The price meet my budget, deliver on time and the product excellent

great deal and ffunctionality

Gracias por todo

Pleased with the purchase, the pouches are well made and have not separated after 2 months of use.

Great as always. I have been getting these for our fishes from this seller. This is our second or third order. My goldfishes are very very happy and this lasts us for 4 to 5 months. Fish tank water is very clean too if I may say so. Thank you CNZ Aquarium. I recommend this product and this seller to everyone.
