"I bought the Aqueon 2."

This will retain much of the bacteria needed. It's far superior to manually scooping out the water from the fish tank. Initially this was used as a sample packet came with our aquarium. Aquarium tubing is scarce where I live during the pandemic. So they fit in my Tetra filter for the fish tank. In terms of taking water out, it's great. Affluent Romans kept their water and wine in silver flasks for the same reason.

"My betta lives in this 2."

In terms of taking water out, it's great. I even poured in extra to help with the healing. I am able to use each cartridge for about 5 weeks, before it needs to be replaced. I bought this to attach to my Tetra whisper 20. My tank is always clean now and the fish are growing and happy! 5 gallon Top Fin Enchant Aquarium that I got from PetSmart. I'm glad Amazon had these small cartridges.

"I promise you it fits."

I used to use AmQuel years ago and then spent years out of the aquarium hobby. The siphon works well and does what it should. Couldn't find this at the local pet store and it was cheaper online. It DOES fit, you just have to spend a few minutes getting it on. But this is great utility tubing for a variety of other uses. Didn't use this for a fishtank or to pump liquids through it. The filters are expensive to replace and only so-so quality.

I love all of the API products, especially their easy to use test kits. I like to sit eye level with the tank substrate to see exactly what I am cleaning.

I don't have to work a hard as I did before just to clean my tank. These fish contain silver in a compound that dissolves slowly. These fish contain silver in a compound that dissolves slowly.

It does not last or do its job after that. It's far superior to manually scooping out the water from the fish tank. I'm not sure what's going on with this 1. This water conditioner is a life saver!

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.

"Thank goodness!"

I like API products and this is no different. This water conditioner is a life saver! I bought this to attach to my Tetra whisper 20. They tend to hang up on the edge of the tank. 4-5 squirts in a sink of water, soak my suit 10 min, wring out and hang to dry. They surely don't last in tank very long.

"Hope this helps!"

I have pillows under a tarp, but pockets of water still form. If you're treating injured fins or introducing new fish, this is for you. Make sure you stay on top of replacing your fish every month though! If it it quickly slip on then it wouldn't be as secure and tight as it needs to be. The tap water was coming out around 836ppm. It is much safer to simply to add 3 drops per gallon. Water stays nice and clear, minus the odd algae bloom.

It doesn't just quickly slip on, and there's a reason for that. I decant this to a small 5 oz squeeze bottle and leave the rest in the fridge.

Will be ordering multiple of them for my needs. Another plus has been that it is scratching an itch we had for getting real fish. The one with the fish keeps the tank clean. In the morning I awoke with my fish at the bottom barely able to move. I don't think the review about not replacing the filters is correct. I decant this to a small 5 oz squeeze bottle and leave the rest in the fridge. It didn't kill the fish or cause any problems with the water so I stuck with it.
