Hagen 24 -Pack AquaClear Quick Aquarium Water Filter Refill Cartridge for Power Head Attachment

Great value. Keeps my tank crystal clear. Easy to change. I use two on my 210 gal. Tank in addition to my regular filter. Very happy with it.

All of my tanks have this filter with the paowerhead. I also supplement with bio-media in the center for additional anti-nitrite/ammonia support. This filter Ks very dense thus making my tanks crystal clear

These work so good as an added filter

The filter attachment that can be fitted on the bottom of the of the powerhead isnt really a filter, it is more of a water polisher. It cannot be relied upon as your only filtration....but it really does make a huge difference as far as water clarity. This multi-pack makes the cost of the refill cartridges so incredibly reasonable.

These filters for the AquaClear powerhead cannisters work beautifully. Easy to drop into the cannister. Makes for crystal clear water! Clears white sand particles out of the water. Will pull out excess food before it decomposes into liquid and gets pulled out by the protein skimmer. Requires weekly filter changes or it may clog up with debris and reduce water flow. Reasonably priced. Love the fact that you can buy them in bulk.

I have used these for years to help keep the water clear. I change them every monthly water change. The good thing is, with the price of this 24 pack, they come out to just over a buck per each one. Thats a good price.

Used these along with their power heads for years on a 150 gallon reef tank. They are also a MUST even on a Nano tank like mine. Ends lots of problems!!!!

These are great fir keeping water clean. I replace once a month; takes about 5 minutes per AquaClear filter

Great bulk price.

Great value for the money. We love our filter system. Our aquarium looks better than it ever has. The 24 pack keeps us from always needing filters.
