You know that moment when you risk, and buy a product that you already believe it will disappoint you, yet you purchase it? And later on, upon testing said product, you amaze yourself and apologize (even internally) not just to yourself, but the company itself.... yeah, it pretty much sums up the experience...lol. changed ALL of my filters to this one right here, and I've not had to changed them in 3 weeks, at least. Great price, and an even more remarkable product! Highly recommended

Works well and easy assembly

I purchased these because the ones that were already assembled were a couple of $$ more expensive. I figured I could save the money and assemble myself. It is a bit messy when putting together, but the cleanup is very straightforward. I usually put the charcoal in the bio bags over the sink and then rinse the sink afterwards to help with clean up. I have been using these bags for years and they work really well.
One day I will come up with a method that isn't as messy when assembling, but it really doesn't bother me. It filters the water and cleans up turtle poop. I am happy, it does the job.

I am very pleased with my purchase. Where I live the price for this food is twice as much as your cost. I will now purchase from you. It is well worth it.

I'm always satisfied with each product I purchase for my Fish. My Oscar is 12 inches long. I almost lost her. She didn't eat for 5 days. I purchased a product from chewy and she looks much better.
