[AquaticLife] Question about Nitrate Level
I don’t know if you are using a municipal water supply or your own water. If it is the former, get a copy of their water test results. These are public information, and can often be found on the town or city’s web site. If you can’t find it on the web, give them a call to request a copy. The nitrate level they claim should be listed in the report. Keep in mind, however, that what they report may have no relation in reality with what is delivered to your tap. They have a lot of pressure on them to produce good water at minimum cost, and therefore they will want to test where they can get the best results for those goals.
For those who have an interest, I found a couple of documents talking about reagent expiration. http://www.epa.state.oh.us/ddagw/Documents/pipelinesept2004.pdf http://www.lamotte.com/pages/edu/shellife.html
In the first link, go to page 2 of the document for “Chemistry Reagent Expiration Dates”. The second is done by LaMotte, a company that provides the reagents used in many hobbyist kits (the other big supplier is Hach). This KB article from the Hach site talks about shelf life and proper storage of reagents, and points to t tool to determine expiration date of their reagents (unless you are buying Hach branded reagents the tool will likely not be of use): http://www.hach.com/hc/view.knowledge.base.detail.invoker/PackagingCode=GENERAL-REAG_2/NewLinkLabel=Shelf+life+of+reagents Since the above link will likely wrap, causing you to copy and paste the parts, here is the TinyURL for the link: http://tinyurl.com/6o9bhy
