The artyicle is interesting, but not much credibility. She could have made it up LOL.
Whilst I admit, that the lack of names of the "scientists" dose make you stop and think
I will point out that this experiment has some previous experiments to compair it with.
The authors of the Tilapia experiment acknowledge that previous research by others demonstrated different results: Fish subjected to very low pH would show "general impairment."
But our experimenters also point to an earlier paper (Balm & Pottinger í93)[6] which proposed and demonstrated that acidification can be tolerated if [1] the reduction of pH is gradual and [2] stress from handling or from aluminum ions is avoided.
[6] Balm & Pottinger, "Acclamation of Rainbow Trout to low environmental pH does not involve an activation of pituitary-interrenal axis, but evokes adjustments in branchial structure," Canadian Journal of Fisheries and Aquatic Sciences (1993) 50:2532-41] The results of the Tilapia experiment furthers this claim.
If you read the article fully you will see that the only parameter they lowered was pH.
gH, kH, etc was left at the same levels.
What ever you guys think, fake or real, it is certainly food for thought
