"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.

"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 am new to the hobby."

I love all of the API products, especially their easy to use test kits. I was impressed at the suction and speed of this little tool. 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 had a parasite problem, and had to heal my fishes scales and fins. Sure enough they are back to their healthy coloration and didn't end up dying on me. Washed with hot water several times to get rid of it.

"Great price."

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. I like to sit eye level with the tank substrate to see exactly what I am cleaning. You just give it some squeezes, and the outpouring begins and doesn't take forever. From their own colon or a hole in the ground. I bought this airline tubing to work with my air pump. I had a parasite problem, and had to heal my fishes scales and fins.

"They do the job well!"

I was impressed at the suction and speed of this little tool. I recommend these above all other filter cartridges I have ever used. I can't find them any where's else. Before I did anything with my tank Saturday the TDS reading was in the hight 900's. The chloramines contain a small amount of ammonia. Exactly the same item I purchased from a local store for alot more money! I'm not sure what's going on with this 1.

"I totally recommend this."

Thanks to the Amazon reviewer who mentioned this! I swim 5x week and usually my suits last about 2 months. These filters get the job done, but do plug up quickly when my water is that gross. I used to use AmQuel years ago and then spent years out of the aquarium hobby. The filters are expensive to replace and only so-so quality. Sure enough they are back to their healthy coloration and didn't end up dying on me. However if you want a stress coat, this is perfect.

"8 degrees."

Exactly the same item I purchased from a local store for alot more money! Lastly, the hand pump primes very quickly and the water flow is wonderful. Also some granules of activated carbon will fall out when you rinse them. Put in last night and my water is crystal clear. Now our fish have grown and we've added live plants. In the morning I awoke with my fish at the bottom barely able to move. It DOES fit, you just have to spend a few minutes getting it on.

API 89E First Impressions

"And he is a betta."

I really do need 1 that flows on its own. The ridges interfere with moving the hose around in the tank. I must've measured correctly because it fits great! This tool has made maintenance so much more easy and efficient. More doesn't hurt anything, but it's just wasted. This piping and some electrical tape made it quiet again. Always needing to wash it out, with only 1 small catfish in the tank right now.

"Subtracted from the tank."

These filters get the job done, but do plug up quickly when my water is that gross. Couldn't find this at the local pet store and it was cheaper online. Excellent product, you simply can't beat the price and shipping was bullet fast. In the last two months I have seen this product work its gold. We've got 2 in ours even though the package says to only use one. I used one gallon of reverse osmosis and the rest tap. Frequently changing the filter messes with the aquarium nitrogen cycle.

"Thank goodness!"

Fish possess an antioxidant defense system to reduce the negative effects of ROS. I will purchase this again when needed. We've got 2 in ours even though the package says to only use one. I use water from the tank, but you can use treated water. I have done this a several times with great results. No observable signs of stress in the fish. I am able to use each cartridge for about 5 weeks, before it needs to be replaced.
