Green Light Stump Remover
Anyone has a definite answer to its content? According to previous
postings it is suppose to be pure KNO3, but when I tested a solution of it with the Aqua. Pharm. nitrate test, I got a reading of 0. So, is the problem with the Stump Remover or the Nitrate Test? BTW, the Nitrate Test did have a non-zero reading with some lawn fertilizer that I left standing with aeration. Also, the Nitrate test registered 0 with a solution of Flourish Nitrogen. This doesn't make sense since the Flourish Nitrogen is suppose to contain nitrate. A related question. Know of a good nitrate test kit? |
hagen or tetra. Hagen is probably a little better, but it takes a bit more
practice to get it right. Tetra should be more than good enough. -- Margolis http://web.archive.org/web/200302152...qs/AGQ2FAQ.htm http://www.unrealtower.org/faq |

The hobby kits are like windows, they just don't work properly. The green light stuff is pure kn03. You can verify this by asking for the MSDS sheets where you buy it. -- Need Mercedes parts ? - http://parts.mbz.org http://www.mbz.org | Mercedes Mailing lists: http://lists.mbz.org 633CSi 250SE/C 300SD | Killies, killi.net, Crypts, aquaria.net 1970 280SE, 72 280SE | Old wris****ches http://watches.list.mbz.org |

They're thrown off by nitrite (the instrucstions say so but don't say high or lo) and the color charts are a function of water hardness, I have to use the something in between the salt and fresh chart for my water and I've seen them read zero with a calibrated kn03 stock solution and I've seen them read zero when a LaMotte kit reads 220ppm. The thing seems to work sometimes and if you guess at what the chart should be they're usefull for determining "zero", "low" or "high". When they work. Plus they contain cadmium.

Sorry, but you need to read the directions then ;op They are more than
accurate enough for what we are dealing with here. There is no need to spend $100 on a lamotte test when we are not in a laboratory setting. And there are no digital meters for nitrate. -- Margolis http://web.archive.org/web/200302152...qs/AGQ2FAQ.htm http://www.unrealtower.org/faq |

Well I've seen a three legged dog too... For my requirements, the AP nitrate test kit and the Nutrafin pH kit are very accurate. When used properly, they reflect the conditions I'd expect to see with the variables present. For example: My tap water test for nitrates is 0 The city water report for nitrates is less than 1 When I was cycling a new tank, the first test to show results was for ammonia. Within a week or so, the nitrite test showed evidence there. A short time later, the nitrite test was back to zero and the nitrate test was positive for 5ppm. My 55g tank has supplemental CO2 Tap water pH test is 7.4 My initial KH tests were 35ppm Is it a mear coincedence that the C02 chart calculated amount is 2.4ppm? As I began to add CO2, the pH steadily dropped to 6.8. I added some crushed coral to add buffer, and the KH is now at 55ppm. I've since tripled the CO2 bubble rate and it is now calculated at 26ppm with a measured pH of 6.6. When I had a large fish load, the nitrate tests got up to about 20ppm on a weekly basis. Now that there are less fish, the test does not show as much. When I added many plants, the nitrate test came up zero again so I've begun to add KNO3. It seems to be workin' for my hobby needs, and the plants and fish sure are healty. steve |
You know your remark about nitrite is interesting. In the three
nitrate test solutions I have. The only solution that showed a positive reading contains nitrite and ammonium. Hmm, coincidence? |

Ok, then explain why I got 0 ppm on a solution of Green Light Stump
Remover? As I said, either the Stump Remover is not KNO3 or the AP nitrate test sucks. I was ready to blame the Stump Remover until I got another negative on a diluted solution of Seachem Flourish Nitrogen solution. According to the label the Flourish solution is suppose to contain nitrate. Incidentally, the stump remover label stated that it contains KNO3, it just didn't say whether it was pure KNO3 or not. If pure KNO3 is suppose to register zero in the AP nitrate test, then it is pretty much useless for my needs. The only time the AP nitrate detected nitrate was when I aerated a diluted solution of lawn fertilizer (Scotts (or Scott) Turf Builder). The lawn ferilizer contain Urea as I recall. So after several days, I suppose the Urea was converted into nitrate. Of course this means that the solution is likely to contain ammonium and nitrate as well. |
Have you done it? I checked the website that maintains MSDS, and can't
find it. Incidentally, according that website MSDS is a volunteer program. In other words, companies don't have to submit an MSDS. |

Another test is: Mix 1 tsp of greenlight with 1 tsp if icing sugar. Light it (outdoors). If you see a pink flame and lots of smoke then it's (still) kno3. Please don't rely on hobby nitrate test kits.

It was a long time ago that I researched Scotts Green Sweep that I
chanced upon some MSDS website. It has some plead to manufacture to submit MSDS for the sake their customers. Anyway, I can't find that again, but I nevertheless found the following that may explain the inconsistency between what you stated and that plead on that website. It follows From: http://www.msdssearch.com/msdshistory.htm "Most materials packaged for consumer use are exempt from the requirements of the Hazard Communication Standard (HCS)." Anyway, thanks for that Green Light Stump Remover MSDS. I guess that means that the AP Nitrate test is crap. I dissolved a small amount of stump remover in water and tested the solution with the nitrate test. I got 0 ppm. I repeated this at least 3 times. |
Nope, I won't buy another AP nitrate test kit again. There nitite test
kit and ammonium test kit are pretty good though. |

While consumer products may be exempt, if you dig enough, you'll find a MSDS for just about anything sold. A quick Google found MSDS sheets for liquid laundry detergent, cologne and water (yes water - http://www.sciencestuff.com/msds/C2957.html) Anyway, thanks for that Green Light Stump Remover MSDS. I guess that means that the AP Nitrate test is crap. I dissolved a small amount of stump remover in water and tested the solution with the nitrate test. I got 0 ppm. I repeated this at least 3 times. Strange, I mixed up a batch of Spectracide brand stump remover (100% KNO3) at 1 tsp/500ml and tested with my AP kit and got an instant color change (overkill on the ppm). Perhaps your test kit is old or you didn't add enough KNO3 to register. kev -- Civilization. An organized system of alternatives to the stone age - CJCherryh |
Nope, added enough. In fact a lot of it. Half a teaspoon in one test
tube. |
I suppose that proves Sexton's point about the sporadic success of the
AP test. |
OK, here is a challenge for you. Find out what is in Flourish Excel.
I dare you! Seriously, I really want to know. |
I don't have icing sugar so I used regular sugar. I made a small loop
with a fine wire, and managed to get some stump remover and sugar mixture on it. I placed it over a candle flame. Fizz!! The mixture bursted into flame. Yep, it reminded me of an incidence when I was younger when I made gun powder with KNO3 from my chemistry set. The upshot is that the result from the experiment supports the claim the the stump remover is KNO3. Wow, first experimenting with microbes to generate CO2, now making explosive mixtures, this hobby is getting more exciting with every passing day! |

Oops, must have missed it. All that small prints. :) Thanks.
Oh btw, I found an article on the web about Zebra Danios: http://freshaquarium.about.com/cs/fi...l/aa060799.htm "Zebras are particularly susceptible to Oodinium, or Velvet disease. When purchasing fish avoid any that have clamped fins, or look emaciated, as they may be infected." You know that description about the emaciation is consistent with my observation that they were wasting away. I looked at my surviving Zebras and all looked fine. I think the disease may have come in with the Crawfishes that were temporarily in that tank. I suspect that wasthe case since I did not buy anything for months. Well, either that or the disease was lying dormant in them. |
