Excellent product

Practical

A+++++, Amazing product and fast service

I have been looking for the Original brand of these, I am going to give them a try and see if I notice the difference

Why do these filters come in diffrent sizes? They are for the same aquarium, I had bought these and they didn’t fit. Bought from a different seller with different measurements and they didn’t fit either. I decided to upgrade to the INTANK media holder , and although it’s expensive it’s worth the money. Take my advise. Get the intank media upgrade for the aquarium

Use this in a small salt water tank.

the filters work excellent!!!

I’ve ordered these filters off Amazon many times but just opened the last of my three pack last night and put it in my tank. Now my whole house and the tank smells like either gasoline or burning rubber. It’s horrible! The unused second filter smells the same. I’m not sure what is wrong with these filters but now I’m worried that my fish and coral will die. I also have other pets and kids breathing this in. I no longer recommend buying these filters on line, seems best and safest to get them from your local fish store. This could end up costing me my entire tank and possibly harming my family! Update: the company contacted me for my information and I even sent them a picture of the VOC reading of the filter which was 700! I never heard back or was offered a replacement. And someone else wrote that there was a recall of this filter, I was never notified. Again I don’t plan to order from them again and recommend that no one else does as well.

Great price for item.

Easy to use.
