Answer by ChewyOct 12, 2022
This Large filter is compatible with the Tetra Whisper 20, 30, 40 and 60 Power Filters and the Tetra Whisper 20i and 40i Internals.

What are the dimensions for these replacements?
Answer by ChewyApr 30, 2018
The dimensions for these Cartridges are 4.6 inches (length) by 6.4 inches (width).

Does it come with the carbon prepackaged or is it just the empty cartridge
Answer by ChewyApr 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.

how many plastic frames comes to each box of 12 filters
Answer by ChewyNov 01, 2019
The 8-count and 12-count disposable filter cartridges only comes with one Aerobic Frame with Clip.

Surprisingly better

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.
