Does it come with the carbon prepackaged or is it just the empty cartridge

Answer by Chewy • Apr 13, 2018
This product comes unassembled with empty cartridges. I've listed the following instructions below: 1. Detach clip from Aerobic Frame and slide the filter bag over the frame. 2. Add one packet of Ultra-activated carbon. 3. Press the Aerobic Frame flaps down over the top of the filter bag and press the clip down over the flaps. 4. Rinse under cool tap water to remove carbon dust. 5. Insert the Bio-Bag into filter slots.

DIY Big Dog Water Fountain

I have a Newfie, a Golden Retriever, and 2 cats that all drink from the same water bowl. The Newfie is very slobbery! I made a water fountain out of a 5 gallon oval metal bucket and an aquarium filter. These filter cartridges help filter out all of the slobber and miscellaneous debris from the water. Dogs and cats have clean water, and I'm not rinsing and refilling bowls multiple times a day.

Keep even bigger tanks clean

I use these filters in all 4 of my tanks: 2 that are 36 gallons each, a 75 gallon, and a 95 gallon tank. Even though the filters are not rated for tanks larger

I use these filters in all 4 of my tanks: 2 that are 36 gallons each, a 75 gallon, and a 95 gallon tank. Even though the filters are not rated for tanks larger than 60 gallons, 2 filters on each tank and frequent water changes keep my tanks crystal clear anyway.

The last few boxes I have gotten a lot of black is coming through the white filter when I am rinsing the new ones before putting in the filter on the tank. Previously there was almost no black sediment coming out.

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.

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

Great product with easy installation

I have been using many years these filters which last up to month before having to change out. Also Chewy.com is the best when it comes to fast delivery.

I have always used tetra bio-bag filters. I don't know what this company has done to them, but the last couple boxes I bought can NOT be rinsed. They just turn into a gelatinous gel that falls apart. It clogs up my filters & breaks down inside. I keep using them, thinking I just got a bad batch, but they're all like that. Waste of money. I am buying new filters by Aqueon. They seem to hold up & last much longer. Very disappointed in this product.

First heater failed within 8 hours. Chewy was nice enough to replace it but second one failed within 24 hours. Ended upgrading to a pro heater that seems to be working well. So far so good. Got that one from the manufacturer and chewy was nice enough to refund my money.
