20 years ago nobody cared about bacteria. I still don´t care and I still use GFO with my po4 0,02-0,04 and no3 = 0.
Today there are so many products and stuffs that a lot of people just don´t know what they are doing anymore, just buying and dosing a lot of things.
20 years ago everybody was using HQI, a good Skimmer, Ca reactor, GFO and water changes and a lot of people was very successfully
I believe that people have lost their power to question and evaluate what makes sense and what doesn't
I still follow the rule : keep it simple as possible
Just my two cents
Cheers
Hey.
I’m not 20 years, but 15 in a hobby, but even then, for the initial new tank, at least everyone recommended taking either a little water from a old tank, or live rocks, or live sand to initial the cycle.
After that, the tanks matured, sometimes up to several months before something could be planted there.
During this time, much has changed. We mean aerobic and anaerobic bacteria that do all the work of denitrification of water. There are a large number of species of such bacteria.
Different systems use different types of bacterial strains and, accordingly, and their nutrition.
At the same time, the launch time of the tank was also reduced. Instead of long months of maturation (bacterial reproduction), today you simply add bacteria and food for them.
For example, Korallenzucht offers the launch of a new tank within 2 weeks.
