 Re: Chemistry?
Gabe, check out www.wetwebmedia.com, this site has many articles that you may find helpful. But in a nut shell- Fish poop is basically ammonia which is toxic to fish and invertebrates. Bacteria convert it to nitrite which is also toxic but is then converted to nitrate which is less toxic to fish. pH is a measure of the negative ion concentration or more simply-how acidic or alkaline the water is. A pH of 7 is usually considered neutral or middle range. Acids have a pH below 7 and alkali have a pH that is higher than 7. Our blood has a pH of 7.4, sea water has a pH range of 8.2-8.4. Bleach is an alkali and vinegar is an acid . Tap water is usually 7-8. Alkalinity is related to pH but I will let you figure that on your own as it is more complex.
