I have always used Prime. Today I changed about 50% water in my 20 gal tank, and forgot to add the Prime. I came home 4 hours later to more than half of my fish dead. Use it. Protect against ammonia. My tap water is perfect for all other measurements, and this has never happened, even with 100% water change, because I always use Prime.

My wife loves this item! She drinks water and lemon all the time and complains of seeds and chunks of lemon mixing in. With this bottle it was easy for her to keep them separated and still enjoy the taste. I purchased this item at a discounted price.

Very impressive immersion. Im 42 years old and some games scared me enough to jump out of my seat. Relatively easy to set up. Size is a little clunky but you get comfortable with it pretty quick. Definitely a must buy!

This insert is ideal for carrying camera equipment in a bag which was not designed as a camera bag. It holds my DSLR, video camera, and small point and shoot camera along with some accessories. I am quite happy with this product.

I used this product to stop an oil leak when my oil lite continue to flash, once I added this additive the lite eventally stopped.

This set of shears are great, much better than I expected for the price. They appear to be well made and are quite sharp.

I have a Dell Studio 9000 running Windows 7 with an Intel i7 processor and two 500gig hard drives. My backup is a Drobo unit with two 1 TB drives. I installed the NTI Backup Now Ez 2010 software and followed the simple instructions on the screen. The software was slow to start and slow to run. When the software finally got going, it identified the files I wanted to backup and found my Drobo drive. I indicated a schedule of 6PM...it was then 5:50pm. Waited for the software to start my backup. The backup supposedly started...but wait...in the lower left corner of the screen, an error message with a big red circle and a big white x. The message "Backups not started". At this point the software simply froze. Nothing I could do would make it reset or do anything. Frustrated, I removed the software and reinstalled it again. Still very slow program. I carefully performed the setup all over again. Got the same error message and a freeze. Reinstalled it two more times. Same problem. I removed the software and am returning it to Amazon.
