Not the best choice in aquarium heaters and coolers

I don't like that the filter only gives you one hose placement option. Also, the hose doesn't snap so it doesn't sit properly. It just sits in the rust hole and the pipe has to be adjusted to the water level.

Pros
  • Certified
Cons
  • Big and bulky

1st order good, 2nd order defective

Trying an underwater filter. A flat sponge has been added on the bottom to promote healthy bacteria for the best water condition and inhibit algae growth. 2nd time I buy. Sent a second one with defect problems, but the first one is fine in the nano tank.

Pros
  • Good marks for support and durability from testers
Cons
  • There are disadvantages

Good for the price ($13)

I only bought this because I wanted to filter a container full of sea water. Multiple photos and videos included. When I bought it it was pretty cheap at $13 but now it's back to $18. I wouldn't buy it for €18. Since I need a second one for the other half of my container, I bought another used one for $10. The first picture is after 3 hours of filtering muddy sand water, I don't know if it was a filter or just sand deposit. The second picture is different. 3 hours filtration, total 6 hours…

Pros
  • Great price
Cons
