Prime is great. Its recommended the most on tropical fish message boards. I used to use Stress Coat, but you have to use a lot more of it, and therefore you go through it much more quickly. the 500ml bottle of Prime lasts me many months for my 55, 20 and 10 gallon tanks. The amount you use is very small--only one capful per 50 gallons. When doing partial water changes, you only use a few drops! Its also safe for all fish and invertebrates. Its a must-have for any tropical fish owner, as it makes the water safe for your fish!

These wine stoppers and pump arrived very quickly and in perfect shape. The instructions were on the outside of the box. They are not super thorough instructions, but it is fairly self explanatory. It was very easy to use. I washed everything before I used them.

Handle works well but is not really needed, it gets in the way in the car but is convenient around the house.
