"My betta lives in this 2."

I bought this to attach to my Tetra whisper 20. I always deep clean my humidifier every week-week and half regardless. This piping and some electrical tape made it quiet again. I always deep clean my humidifier every week-week and half regardless. The chloramines contain a small amount of ammonia. When they disinfect a repair site, they are normally only using chlorine. Then I went ahead and bought a huge pack of them.

Marina 11201A1 Final Thoughts

"They do the job well!"

Got here on time, perfect packaging, rinsed easy and fit in my filters perfectly! I don't think the review about not replacing the filters is correct. When they disinfect a repair site, they are normally only using chlorine. Put in last night and my water is crystal clear. I decant this to a small 5 oz squeeze bottle and leave the rest in the fridge. Beats the heck out of those expensive suit cleaners. It's been three months and the water has remained clear and my fish healthy.

2. Marina Blue Fine Nylon Net with Handle, Aquarium Maintenance Tool, Blue

Marina 11273 First Impressions

"I like it."

This includes check valves on both. The filters are expensive to replace and only so-so quality. Aquarium tubing is scarce where I live during the pandemic. Boiling water does more to kill mold and bacteria, so save your money. Then I went ahead and bought a huge pack of them. The picture shows an aqua color and mine is orange. I had a parasite problem, and had to heal my fishes scales and fins.

"I highly recommend it."

A few names we've had were Carlos, Phobe, Feesh, and Chaz. From their own colon or a hole in the ground. I must've measured correctly because it fits great! Overall, these are easy to use filters& seem to do a good job. I have never had one tear or fall apart under any circumstances. I like API products and this is no different. I haven't tried looking for alternative brands.

"These filter cartridges."

Then I can walk away and come and move it to the next pocket or re-position it. It's been three months and the water has remained clear and my fish healthy. We've got 2 in ours even though the package says to only use one. No observable signs of stress in the fish. I tested it again this morning and it's down to 838ppm. I have never had one tear or fall apart under any circumstances. Excellent product, you simply can't beat the price and shipping was bullet fast.

"Also, have some patience."

Make sure you stay on top of replacing your fish every month though! This piping and some electrical tape made it quiet again. Water stays nice and clear, minus the odd algae bloom. If placed the other way, the carbon can be pushed out into the aquarium. Overall, these are easy to use filters& seem to do a good job. Works great to keep the purification process going in the humidifier. This will retain much of the bacteria needed.

"I have a 2."

The one with the fish keeps the tank clean. You just give it some squeezes, and the outpouring begins and doesn't take forever. So they fit in my Tetra filter for the fish tank. I have two goldfish and about 12 khuli loaches in a 20gal tank. Fish are aerobic organisms that are susceptible to ROS. I must've measured correctly because it fits great! I hope you found this review helpful!

GreenJoy Final Thoughts

"48 the decision is easy."

Thanks to the Amazon reviewer who mentioned this! Great price for filters that are ready to go, with no assembly required. I bought this to attach to my Tetra whisper 20. I recommend these above all other filter cartridges I have ever used. If you look inside the box you'll see dust and stray granules. I have used marine land bio-wheel pump and filters for the past 20 yrs. They tend to hang up on the edge of the tank.

"No need to rinse."

A few names we've had were Carlos, Phobe, Feesh, and Chaz. 5 years now and I truly believe they help keep the humidifier and water cleaner. Exactly the same item I purchased from a local store for alot more money! I really do need 1 that flows on its own. The picture shows an aqua color and mine is orange. Then put hose in your bucket and viola, it will draw water! So my 12 pack will probably last for quite some time.

MarineLand PF0350B Final Thoughts

"And works."

We use it when we clean& change out water. 5 years now and I truly believe they help keep the humidifier and water cleaner. In my opinion there's nothing better. I don't think the review about not replacing the filters is correct. Easy maintenance of tank filtration once tank is fully cycled over a few months. I am able to use each cartridge for about 5 weeks, before it needs to be replaced. Okay, I don't own an aquarium- probably never will.

"Only time will tell."

If it it quickly slip on then it wouldn't be as secure and tight as it needs to be. I bought this to attach to my Tetra whisper 20. I used to use AmQuel years ago and then spent years out of the aquarium hobby. Excellent product, you simply can't beat the price and shipping was bullet fast. It is much safer to simply to add 3 drops per gallon. Great price and will for sure be ordering these again. I hope you found this review helpful!

If placed the other way, the carbon can be pushed out into the aquarium. This water conditioner is a life saver! Then put hose in your bucket and viola, it will draw water!

"And he is a betta."

Water stays nice and clear, minus the odd algae bloom. These fish contain silver in a compound that dissolves slowly. This is my go to water conditioner and stressed fish treatment. Don't claim to be an expert, but I've never heard of that. I was impressed at the suction and speed of this little tool. The ridges interfere with moving the hose around in the tank. I hope you found this review helpful!

Tetra 16448 Final Thoughts

"This why i rated 4 stars."

I'm not sure what's going on with this 1. Fish are aerobic organisms that are susceptible to ROS. I used one gallon of reverse osmosis and the rest tap. Its quite hard to push it on to the air pump. Works great to keep the purification process going in the humidifier. I change my filters every 2 weeks with a water change and my fish have lasted years. It didn't kill the fish or cause any problems with the water so I stuck with it.

"Highly recommended!"

I've been using these filters in my aquarium for years. These fish contain silver in a compound that dissolves slowly. So my 12 pack will probably last for quite some time. Yes I know, they aren't supposed to live that long and no I can't prove it. However if you want a stress coat, this is perfect. It doesn't just quickly slip on, and there's a reason for that. Have them on subscribe and save now.

"I love these!"

I am able to use each cartridge for about 5 weeks, before it needs to be replaced. I use water from the tank, but you can use treated water. I just change them when they get clogged. API Stress Coat is a phenomenal product. From their own colon or a hole in the ground. I wish the length of the section that is in the tank was about a foot longer. Works great to keep the purification process going in the humidifier.

Overall, these are easy to use filters& seem to do a good job. Then I went ahead and bought a huge pack of them. This piping and some electrical tape made it quiet again. I like to sit eye level with the tank substrate to see exactly what I am cleaning. I used one gallon of reverse osmosis and the rest tap. I don't have to work a hard as I did before just to clean my tank. The siphon works well and does what it should.

I must've measured correctly because it fits great! If it it quickly slip on then it wouldn't be as secure and tight as it needs to be. It's been three months and the water has remained clear and my fish healthy. I checked the pH this morning and it was just slightly acidic at 6. I hope you found this review helpful! I really do need 1 that flows on its own. This tool has made maintenance so much more easy and efficient.

"Have it on low speed."

Then I went ahead and bought a huge pack of them. Fish possess an antioxidant defense system to reduce the negative effects of ROS. I bought this airline tubing to work with my air pump. The filters are expensive to replace and only so-so quality. I had a parasite problem, and had to heal my fishes scales and fins. The auction begins with just a few squeezes even my young nephew could do it. So, lots of snipping and fitting on various stems.

"I have a BioCube 29."

If you're treating injured fins or introducing new fish, this is for you. I've been using these filters in my aquarium for years. Water stays nice and clear, minus the odd algae bloom. I even poured in extra to help with the healing. It DOES fit, you just have to spend a few minutes getting it on. Great price for filters that are ready to go, with no assembly required. I am able to use each cartridge for about 5 weeks, before it needs to be replaced.
