Review: Owned for 7 month and havent cleaned once. - Bought this to start a new 10 Gallon planted aquarium. This has been extremely quiet, efficient, and kept my water clear. I did use "Chemi-Pure" blue all in one filter media inside this canister and I have not once opened the canister to clean it and my water levels are perfect. I have only needed to clean the water exit plastic piece where multiple hole water spout that easily comes off is. It did take a bit to get the hose on the actual pump however once its done its good to go. This was well worth every penny spent on it. No water changes needed just adding water to my tank every few weeks. I have lost 0 fish and my plants have been flourishing. Pictures show the 7 month progress. I am buying a second one of these for my other tank.
Review: Inexpensive AWESOME filter system! Will be buying the larger one when I upgrade my tank - I have a 15 gallon tall tank that a hang on back filter just couldn't keep clean. Was going to go for an expensive name brand cannister filter setup, and then found this for cheap. WOW I was impressed! Lack of instructions and stuff, but once I figured it out, this is the BEST filter I have ever used! Its quiet, SUPER efficient, and super easy to use! Lack of instruction on which filter goes where, but if you start out with the course filter (black?) on top, and then go finer and finer to the bottom (to the thinner white filter), its best. I actually put a carbon media filter bag between the finest filter and the sponge filter and it clears the water up QUICK. This thing filters the dirty water through the lid to the bottom out through the pump. I also installed a primer bulb from a cleaner pump into the inlet hose (cut the hose about a foot back and installed it there) to prime the filter. Works great!

### ⭐ Great till it’s not.
*by D***G on January 15, 2025*

This thing work so good that I bought 2. But both of them failed after 2 years and leaked water all over my apartment multiple times. I assumed it was something i did wrong initially. But after a certain amount of time the wheels fall off. The final straw was when my outtake pump failed and couldn’t stay up right. No matter what I did to try and tighten the nut, it just kept falling over, and either twisted the tube causing water to pump out everywhere or the last straw for me was this slow leak. The gaskets are its critical failure point. Having 2 of these helped me realize they suck. The 1st one I purchased did this so I just put away, then the 2nd one did the exact same thing. This happened after a couple of years. Save yourself a headache and most likely the health of your aquarium and pay the extra money for a name brand. All these no-name Chinese companies are the same. Pump and dump. Again it works fine up till a 2-3 years. Then the gaskets fail. This is a critical failure point. Thank god I was home when it happened, it could have cause an electrical fire. Don’t risk your family’s or pets lives on this garbage.
