Review on 🐠 Tetra Whisper EX: The Ultimate Silent Multi-Stage Power Filter for Aquariums by Peter Whitney

PRO: This filter picks up moving objects in the aquarium quite well. The cartridges and water flow are well contained if you're careful to snap the top of the filter, which is easy to miss, BUT it's easy to do when you realize there are notches on the top of the filter. The device currently costs 28.43, so you can't beat that price. CONS: The cost of running this filter is as and/or worse than Marineland with their ridiculous C and E wagon costs. DO NOT make the mistake of subscribing to these filter cartridges. I subscribed to them for 8-9 for 4 packs which is not great but not bad either. I didn't follow their prices and was charged $12-13 and $19.93 on top of the current $9.37. There are no DIY materials for this filter cart, although my first 2 cart orders were wrong I had to make my own. The cassette frame itself doesn't hold together too well, even with the carriage designed for them, but unless I taped them in place, with other media they just popped open as soon as you pulled out the filters. I've tried various ways to fix this problem as it also happens with the right carriages, but if you want a 100% solution you can just stick a small piece of tape along the bottom of the frame. The running-in bath and especially the final coating for the pipe is very small. You can easily crush the end grate during cleaning. I have no opinion on their design for the bio portion of this filter. Time will tell.
