Zoo Med Carbon Bag for 501 Turtle Filter: Enhance Water Filtration with Carbon Media Review

They work great but for the 501 you need 2 filters every change. I wash them occasionally and reuse the filters and they seem to continue to work well after a good rinse.

Do not buy. If you have already ordered, please cancel the order. This charcoal insert is why Zoo Med's superb filter is on sale. Smooth surfaces keep organics out and my tank was left with high levels of ammonia for several weeks. That does not work.

Thanks to this, the Zoo Med filter works very well; clear water and ammonia to zero.

Filter 501 works! I have a 50 gallon tank of about 1/2 inch with a 6 inch red tube spool. All was well at first, but as The Flash (that's his name) neared the 6-inch mark, the carbon bags couldn't keep up. .

I don't know why others have had bad experiences with this activated carbon bag, I have 511 and it came with the bag, I put it in as the filter instructions said and just replaced the bag with a new one over a month ago {March/31}. Anyway, he did a great job keeping my {18x24x14} turtle tank clean and odor free. One thing I noticed when I got the new charcoal bag is that the box says to put the charcoal bag on top of the ceramic filler. My 511 instructions state that the ceramic filler must…

I use Zoo Med and Fluval filter bags in the 501. Fluval is cheaper due to the use of bulky (scrap) chips found in other processing like high tech municipal Substances for treatment plants are left over from the filter bags. The processed granules in the Zoo Med sachet are actually a high-end product and the sachet helps facilitate water flow. Mesh bags like Fluval and those you can buy and fill yourself often have spots that clog quickly. I don't know why Zoo Med packs don't work for some…
