Good filter: Filter accessory

Get this for a 5 gallon tank, works great. I'm glad they offer a pair in each box because I have to change them every month. Good price.

Pros
  • OPTIMAL FILTRATION: For optimal filter performance, replace cartridge monthly or more frequently when heavily soiled and filter flow is reduced.
Cons
  • Nothing here

Easy filter change

Purchased specifically to replace the original filter. Came quicker than expected. Will buy again. Very easy to change.

Pros
  • CONTAMINATION REMOVAL: Activated carbon removes organic contaminants that can affect water quality and cloudy water.
Cons
  • Appearance

Easy to use - fish and aquatic animals

I've had a few that don't filter very well or don't fit, but they're great. I used to have to change the filter every two weeks because it started clouding up, but now I can last a month.

Pros
  • HANDS DRY: Easy to install - Easy to replace - No need to get your hands wet.
Cons
  • They could have gone with a newer model

My fish is dead. Shit.

Unfortunately 15 fish died as a result. I can't put it down to anything else. And I preferred this type to newer filters. I'm considering getting new ones. And try again.

Pros
  • PREMIUM REPLACEMENT FILTER CARTRIDGE: Keeps the aquarium water crystal clear and the fish healthy.
Cons
  • Updates available

Works Well - Aquarium Pumps and Filters

We just bought an aquarium and bought these filters for it. The first one didn't last as long as I thought it would, but the next one lasted over a month! The water only got a little cloudy so we changed it but I'm sure we could have gone a little longer.

Pros
  • DIMENSIONS: 2.25L x 0.5W x 5H inches. Product may ship in white SIOC packaging depending on demographic region.
Cons
  • I don't like it at all, everything is fine

Does what it should.

Filter cartridge for very small filter - Nano Tank. It fits the small Koller filter that came with my 6.7 gallon tank. Tetra also makes a small cartridge that fits the same type of filter but looks completely different. I think I like this one a bit more since both sides are the same. So if one side is clogged, you can get a little more out of the cartridge by flipping it over.

Pros
  • Koller Products & Hawkeye Aquariums: Replacement cartridge fits Koller Products filters and Hawkeye filters for the following aquariums: 2.5 gallon AquaTunes Aquarium with Sound Sleeper (B00HH7UVYO), 3.5 gallon AquaTunes Aquarium with Sound Sleeper (B00HH7UW1Q), AquaView 3 gallon (B01M4LNYWS) , 4.5 gallon aquarium (B01JS39E60), 5 gallon aquarium (B00KIRR8BY), 6 gallon 360 aquarium (B007R5C6CG), 6.5 gallon aquarium (B0182CAHWS), 7 gallon Aquarium (B01JS2NNJA), Smart Tank 5 Gallon Aquarium, Smart Tank 6.5 Gallon Aquarium (B086D9B85Q) and Smart Tank 7 Gallon Aquarium (B0865LG56Z).
Cons
  • Some disadvantages

Really bad filter considering how much it costs.

I recently placed an order with a reputable online fish shop that has had at least one mess with their small orders in the past (hey, big breeders who sell mostly to shops and large aquariums and not to individuals). This time I got 2 bettas, even though I only had one tank for one betta. I ran a Revain (I'm disabled and mostly housebound) and found what looked like the perfect tank. I didn't have time to repeat the cycle so I added some Tetra Safe Start bacteria and hoped for the best. The LED

Pros
  • PRE-ASSEMBLED - READY TO USE: No assembly required, no mess.
Cons
  • poorly thought out
