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. |

about... 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)." 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 |

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. |

Well, either that or the disease was lying dormant in them. Velvet is really east to spot if you shine a flashlight on them. You'll see very obvious tiny grains of sand looking dots all over the fish. They're quite small but you'll see zillions of them like a light disting of icing sugar, except sand colored. I use acriflavine but any decent antiparasitic will work. The but neds light to photosynthesize so even a blackout will cure them. -- 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 |

WOuldn't the get expelled and become free-swimming (then die). Good point. Have you gotten a full cure with a tank blackout only? I've never had the misfortune of battling velvet at home (knock wood). In store tanks were we used formalin/malachite since blackout wasn't possible in the racks. -- __ Elaine T __ __' http://eethomp.com/fish.html '__ |
