MaximalPower Universal Humidifier Water Tank Cleaner - Compatible with Drop, Warm Cool Mist Humidifiers, Fish Tank, Droplet, Steamers - Pack of 10

after only a few days of use , these fish really seem to be working great . I have noticed a difference in the dust like residue on furniture and the water sparkles .

Easy to use! Fast shipping and works great!

It keeps me from cleaning it every three days.

Economical and efficient. These work just as well as the expensive name brands. Nice to have a ten pack so that you are not buying new ones every month or so.

i like using these and found them when i went to put one from the store on my order. what a great deal, 10 fir a little more then one in the store,plys it got here in a few days

They work just like they are supposed to.

Convenience availability and not having to hassle lines at store

These seem to work well at keeping my humidifier from accumulating hard water crust. I love the cute fish design!

first they dont sink at all. but not sure if my water is more cloudy or if im seeing a shadow feom the new color in the tank

was not able to try this out due to the size is to large to fit threw my humidifier opening ''only use the small little egg chapped filters''
