The traditional recommendations for alkalinity seems to be 80-120. I've seen recommendations up to 150ppm.
For many years I did this and it put my in a vicuous cycle which required obscene amounts of acid and bicarb. Since adopting TFP I've ran alkalinity at 50-60ppm, which results in much slower pH rise, and barely any need to add bicarb. It seems much more stable.
What's the basis for the traditional recommendation to keep it at 100ppm+?
