Maybe you do. Sometimes the symptoms aren't obvious, or maybe you just don't notice. If you stopped dosing you could see an improvement in the fish.
But hey, it's your choice!
And thanks everyone for the help!
Back up here.
WHO said this
Doseing more than the recommended amount (1 capful for every 60 gallons once or twice weekly) is shown to have adverse affects on fish.
and where is the support for this?
You are trying to suggest that fish get disease due to adding traces daily or more than 2X a week? Where on earth did you get this information and did you test it under any sort of controlled conditions? I mean if I keep Altums, Apistos, any species of Cyprinid, Discus, virtually any sensitive tetra, catfish, loach, shrimp and invert.................
Long and short term cases, and many replications, where is my disease?
Why have I not seen this disease and adverse effects? If such diseases are "shown" to be due to frequent trace dosings, you need to be far more sure than a mere guess.
I have not use meds in 15+ years and at any time in the past, it was never once correlated with trace dosings.
So if what you claim is true, why do not I not see it?
I cannot obviously say why you have issues, or those of others, but there are 1001 and 1 ways to kill fish, stress them out and induce the wide range of diseases listed by you above.
I mean if it's a direct cause of disease, then I should have seen some evidence of this and so should more folks on this list and others that have kept planted tanks over the long term. Note, this has not a thing to do with you personally, I'm saying you need to come up with a lot more support for your claim there because it does not match the observations(not even close).
I have a control and the tank does not have any short acute of chronic long term issue due to trace dosing, day night, high frequency etc. If you really think this, I'd suggest you go back and figure out what else you might be doing wrong that causes diseases.
I cannot rule out every possible reason why an aquarist gets a disease, no one possibly can, but I can rule out why one thing might/might not.
That's how you go about thing, one by one, takes work and time. Then you can focus on what might be causing the issue. Many folks that do not even add traces have those diseases listed, how do you explain that?
There may be many more reasons that have not been considered when making the claim. That is far more likely given the observations and they have support(poor water quality, lack of water changes, wrong temps, KH's, sick dying plants.......poor use of CO2 etc)
The doubt is much more upon your statements, but likely someone or web site full of beans put this into your head without any support which you took to be true(many do this-do not feel bad). Prove me wrong and explain how many tanks have never had such issues ranging from 2 gal to 1600 gallon and 20 years?
If what you said is true, then I must see these issues in my own tanks, however I do not, so these claims cannot be true.
Now you do not have to fret and worry over fear based logic and folks know their fish are not going to get disease due to trace dosing.
So there's a method to why I said all this, and it helps folks from getting stuck in myths, fear and mere guessing....
