Rated 5 out of 5 by from Great Product I think this a great idea and should have been around long ago. Recommend to anyone with large tanks.

Rated 5 out of 5 by from Simple to use I love the idea of this, because I don't have to wait for the water to change or pull up filter to check when to clean.

Rated 4 out of 5 by from This product is good I like this product because it takes the guess work out of trying to figure out when to change the filter. It used to be a part of the four filter pack but now you have to purchase it separately. I would like to see it back with the filters again.

Rated 5 out of 5 by from I like using this particular product. The reason I love these Tetra Fish Time Strips is because it makes it so much easier to remember when to change your filter. Even though you could just write it down on the calendar and remember to do it the same day every month I like this way better because I can walk by my fish tank and physically see the time strip changing colors and can tell when it gets close to the end it's time for a clean tank, filter, and time strip. I highly recommend them.

Rated 4 out of 5 by from Useful product - easy to use I I like using the Timestrip as an easy reminder to change the filter. I hope my pet store will start carrying the strips soon due to the extremely high shipping costs charged by Tetra!

Where can I order the Whisper EX Timestrip Replacements? I had gotten them here at your website but I can not order them here. Please help. I find the timestrips very helpful.

Good morning, Thank you for your inquiry. Unfortunately, the time strips have been discontinued and we only have some on hand to send out to our consumers. We will be emailing you directly for more information about obtaining them directly from us. MINI

How do you use the timestrip?

Asked by: JudyT
Press down HARD on the button. Sit the timesrip somewhere near the tank where it is very visible so that you can monitor it. Within 3-4 weeks, the white strip will be solid ruby red, and it will be time to change the cartridge. BREX

why can't I watch your "timestrip" video

The video starts to load, then stops saying that it is private. IF I cannot figure out how this thing works so I try the video and that is seemly blocked, then I guess you don't want to sell products to me???
Asked by: ewing
I'm not sure what video you are referring to - I looked on the timestrip product page and the filter product page and did not see a video on either. Please email us directly as to where you are attempting to view a video and perhaps we can help you. All there is to using the timestrip is to push down on the button to activate it, then insert it into the filter cover if you have an EX filter. If you do not, you lay it on top of the hood or the filter that you do own. BREX
