Just a word of caution to buyers who are unsure of sizing. this filter measures 3.5" x 5". the product description listed is not accurate and is actually the packing size. Otherwise a great product.

Everyone is going to "prepackaged" filter cartridges. I prefer the flexibility of putting whatever I want into the filters. I prefer 1/3 activated charcoal and 2/3 ammo chips. This keeps the tank clean and also keeps the ammonia down since I keep a heavy load of fish in my tank. I can't seem to find these filters in my pet store, so I get them online. I change my filters every two weeks, so when I run low, I order more and they are delivered before I need them. I highly recommend these filters.Read Best Reviews of Tetra Whisper Unassembled Bio-Bag Cartridges Here
I have found making my own filters allows me to add more activated charcoal carbon filter media. The small package found in most filters does not (in my opinion) clean enough because they have only about a handful of filter media inside.DO YOU WANT BETTER FILTERIZATION?:
I now use the unassembled filter bags -I add enough activated charcoal to FILL the filter from bottom to top of the filter sac then the water flows thru the charcoal and NOT around it. BE SURE TO rinse the filter with water to remove loose charcoal before re-installing in the filter frame.
HOW I MAINTENANCE THE TANK:
I maintenance the tank weekly or bi-weekly, first I remove the decorative accents from the tank so I can clean the rock by a gentle stirring motion,(being careful not to bump into the fish) then I loosen debris in rock with the tank water siphon vacuum tube removing 1/4 the water. I wipe the glass with clean paper towel if needed to remove salts or other debris that accumulates on the glass, I add some fresh water to top off the tank, add de-chlorination, test the water (using a water test kit) and change the filter after filtering with old filter for 45 mins 1 hr to remove the majority of debris loosen from gravel. That routine seems to keep the tank clean and the goldfish healthy.
BEFORE vs AFTER: I use to buy pre-made, and had fair results for cleaning but after I noticed the pre-made have very little charcoal in the filter sac, I decided to make my own and add more filter charcoal. Now that I have increased the amount of filter charcoal (they call it activated carbon) media, the tank water is MUCH cleaner at least 50% cleaner overall.
KEEPING A CLEAN TANK SEEMS TO HELP FISH WITH SWIM BLADDER DISEASE: Goldfish may gulp and burp air to alter the pressure in the swim bladder. I have one fancy goldfish that gets an air in the bladder (this bladder disease leads to problems where the fish has trouble with buoyancy in the water -this is more like a temporary condition that can be managed.) If the fish seems floats up to the top while swimming and seems to lay on side or back after floating to top (this may happen ccasionally because it gets air in the belly)I have read online keeping the tank clean helps prevent this often genetic buoyancy disorder
HELPFUL TIPS: I also try to add the food in the water downward stream to prevent top feeding which encourages air in the belly intake.
GREEN PEAS TRICK MAY HELP swim bladder buoyancy:
1) Defrost 1 to 2 frozen peas. The peas must be very soft.
2) Gently squeeze the peas to free them from their skins. Discard the skins.
3) Put the skinless peas in the fish tank. Allow the affected fish to eat at least 1 of the 2 peas. If the fish will not eat the peas, remove the peas and try again later.

FINAL THOUGHT:
I found that often I can get a better deal (lower price) buying through AMAZON than the pet store I have checked the prices with several pet stores vs AMAZON, so if you plan ahead you can order the items and have them ready to use, when needed.
Want Tetra Whisper Unassembled Bio-Bag Cartridges Discount?
I own a Tetra 100 gph internal filter for my Turtle tank. It takes the large filter cartridge. I replace them almost once a week. At first I tried Tetra's newer all in one type, where you don't have to add the charcoal and there is no filter frame to deal with. I had lot of trouble with this and sometimes it got clogged up too quickly because it would sag a little. Stay with Tetra's traditional style and save money by installing the filter onto the frame and add the charcoal. It's less convenient but things work out better. The 12 pack at Amazon is about a $1 each filter which is A LOT less than the single pack or any packages Tetra sells. So if you have a LARGE Tetra filter (internal or external), this "old school" filter package is better and a lot less money than all the others Tetra sells.Save 65% Off
