I even cited the link:
Did you even bother to read it?
If your info was so well known I don't think you would have to so valiantly defend it.
Whether the information is known or not does not in any way, discredit it.
I offer support for my statements.
EI and many of the articles I have written have been read and are easily accessible on line. Excess PO4 is a good myth and like all good myths, it is hard to kill.
I got the idea from a guy who makes a living with fish and plants, and has been doing planted tanks for 20 or so years.
Well, I have curiously also have same credits
It is now a pee contest? Is this how you "valiantly" defend your
I offered clear examples that falsify this claim, many of the people on TPT have been to my home, seen my tanks over many years. You have not addressed how my tanks and those of many others do quite well and lack algae(BBA or others) at very high PO4 values.
Simple question, one which you have avoided. Perhaps you should ask yourself the question. Investigate, see if you can learn more. This path will make you a better aquatic gardener.
you shouldn't make a blanket hypothesis when you don't know all the info. for example my tank might have 10x the amount of po4 your tank does, therefore causing the bba to thrive in my tank.
Your tank has 100 ppm PO4?
I'm extremely safe in my position when I made such statements.
I've demonstrated 1000X of times that excess PO4 cannot be a cause of algae independent of other factors.
If you have dependencies, well, then, it's a poorly designed test.
You cannot say much about why you had those results. There are 1001 ways to mess something up.
All it takes is for a few people to show a nicely done planted tank without algae issues and high PO4 to falsify your claim.
My position is one of falsification, yours is not. My methods are rather clear in the fact I do not have dependent factors. Yours MUST have dependencies.
If that is not true, then "magic" must be invoked for my tanks to exist.
In order to find the cause of something, you need to falsify each likely hypothesis, you narrow the choices down by falsifying each tested hypothesis. When you are left with 1-2 etc, then you go back and see if you can confirm it. You still cannot ever be 100% certain as to cause, but can be certain about falsification.
plants don't need massive amounts of po4 and I seriously doubt the phos guard is removing 100% of it from the tank or my plants would be dying after a few weeks, which is exactly the opposite of what's happening.
So did you even bother to test to confirm the PO4 is gone or at some low residual or is it a guess? I'm not so confident as to debate such a topic without covering my bases. I'm not so sure we can say the same for your methods.
Absolute removal is one issue, but a low limiting level does not imply 100% removal from the water column, it only suggest that one nutrient is now more limiting than another. So plant demand for CO2 drops because the most limiting factor is now PO4.
Liebigs law accurately predicts this, this is not a "causal" theory, this is more than a strong Science based theory, it's a law.
If you added more CO2, then added the PO4 back, then you would see that this is true. Whether you believe me is not my point, the evidence is there and you owe it to yourself to investigate that this is the case.
Maybe I've been lying to everyone for 20 years?
Noone has all the anwsers and you really should be less critical and negative about things Tom, makes you look like an old grouch.
Hehe, really? Name calling are we? I attack the topic, not the person.
An idea should stand on it's own merits, not because someone is a nice guy. Used car salesmen are nice guys, but we do not believe everything they say either.
Prove what I say is true, to yourself
Then you will know.
Right now, you don't.
