Research paper is valid when fits one’s narrative.
There are countless threads about fish health relationship to NO3 levels with references to hundreds of scientific research documents pointing clearly in one direction. But no, the little opposing group will still try to dismiss it based on a claim that no research was conducted on their own glass box and also not in their living room."Research paper is valid when fits one’s narrative". So does this mean that Tom barr's article is only true because it fits his narrative?
See? More is coming.And honestly, peer reviewed scientific University articles mean little to me. I don't know of one that takes place in a home hobbyist aquarium.
At the stage your aquarium is in, I would really like to find out why you are experiencing problems when lowering NO3 to half when the most aquariums on this planet with the best plants have 1/10th of that.I do rely on personal experience in my glass box.
I trust the research papers that are consistent in finding similar results and conclusions to each other, not the extreme few.Lets be consistent here.
My PPS fertilizing systems since 2004 recommend 5 – 10 ppm NO3.Can you please point me to the area of article that was to support higher nitrate levels as not harmful to fish?
Many EI tanks are 50+ ppm nitrates for years.
Even the article says fish don't show any symptoms under 100ppm. I routinely dose N to get the water column into the 50 range, check my journal to see loads of pics of my large long lived Rainbows.
I will say it again;With all due respect, they suggest keeping a tank at no higher than 5 to 10 ppm Nitrates. Do you think ANY planted tank here on this board would fall into that category? Or for that matter very few freshwater tanks in general.
For example, some tetras get more colorful, more beautiful when introduced to higher trace element metals. More Cu better colour they get, until they go to shock and die. Even when dead, they have unusually very strong ‘beautiful’ coloration. So much for happy looking fish, right?We are speaking of Nitrate (MG NO3-N/L which converts to commensurate value of 1ppm) between:
1.0-1.5 Pristine environments
2.4- 3.5 Environment has a range of human interaction w/ little harmful effects to aquatic-life.
3.8-5.6 Environments with naturally occurring seasonal disturbances.
6.9-9.8 Measurably degraded seasonally elevated levels of nitrates 1-3 mo. of year.
20-30 Environments that are significantly degraded. Probable chronic effects on multiple species.
20-30 ppm Nitrates is the high measure with "chronic effects on multiple aquatic species".
You don’t want me to test that. It is cruel enough what the research does. I rather take the research as is and keep my fish happier based on their data.I'd like to know more about your experiences with N dosing and fish health. Not something you've read, or an article you can point to, but your own actual experience.
