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.Read more ›
I was buying the Tetra ReptoFilter Disposable Filter Cartridges,Medium, 3 Pack (Disposable) for between 7 and 13 dollars (For three) and accumulated about 20 used ones. I'm glad I held onto them because the "Reusable" plastic frames are identical and now my cost is a buck apiece, saving me more than 50%.
Very easy to to assemble!
I believe this blend compliments the charcoal, while at the same time using more of the space available in the pouches. Also, if you find the little plastic clips that seal the top of the bag starting to loosen up, I've substituted one of those little metal clips typically used to hold sheets of paper together that you pinch to open, like these:
Anyway, I hope someone finds these suggestions useful.

I don't know if it's me, but seems as Whisper has lowered their product quality. I noticed that filter cartridge is not as sturdy after couple weeks of use and has to get changed... Read morePublished 4 days ago by Jaro
These have worked well so far. Easy to assemble for a fraction of the price of the already assembled filters. Would recommend.Published 5 days ago by Jeff
