Great product, poor quality control.
I love the product, but am disappointed in quality control. Got ready to change my bag, opened the box to pull my last one out and was stunned to find a seemingly untorn/undamaged new bio bag with no charcoal in it! See photos.There was minimal loose charcoal in the bag. What I’d consider normal for a 3 pack so I had no reason to think anything had spilled or been damaged. Now I have no bag (during the pandemic when I’m trying to limit trips out) and need a new one ASAP.I guess I’m just curious how this even happens...Good product, poor quality control (and too late for me to return).

When I bought the 10 gallon tank, I wasn’t really wild about the filter because I didn’t think it was strong enough to handle a 10 gallon tank and it’s not. You have to do a lot of gravel cleaning and water changes but the filters whether you get the ones that are already put together or the ones where you Save the plastic and get rid of everything and start fresh with a new cover and put the charcoal in and clip it together rinse the charcoal so it’s not bleeding when you run it through the water and then put it right back into your filter and the filters work really well they catch a lot of gunk. so and it really is whisper quiet. I can’t hear the motor or the filter going even though I could see it going because it’s right next to my bed. But if you get a 10 gallon tetra glow fish tank, just keep in mind that you should also invest in a good Gravel cleaner system. And you don’t have to buy an electric one. I have one that you just pump it it’s like a little gun and you attach it to a hose and it has different attachments for the bottom and it’s the easiest way to do a water change and it really does bring up all the gunk from the bottom . So that’s just the advice but as long as you do that everything works great I haven’t had any fish pass away since I’ve been with this new system and it’s been over a year.

These Tetra cartridges work very well. We use them for a 5 gallon tank, but they will work just fine for bigger tanks. They keep the water looking clean and do not leave any type of film that some filters might leave in your tank. On average, we use them for 3 months before changing them out with a new filter. I've found that these filters are one of the best value pack of filters for the price! I highly recommend these for filtering your fresh water fish tank.
