I have not seen Tom put much interest on bacteria.
Well, I would like to read more from Frank than debating about this.
On my web site I have a sub forum for aquatic microbiology
Most of the articles I wrote for my forum also address bacterial cycling, entire wetland cycling diagrams with references. Just because I do not go into detail here, implies nothing. I am FAR MORE specific about bacteria than ADA is, and I also qualify the and quantify those same specifics. So does Diana Walstad. Simply telling someone that there's a biological imbalance is not informative, anyone can say that. You go down one by one and fairly evaluate and compare. ADA does not do this, I've never seen an article from ADA or AJ that does.
The advice on the labor, trimming, general care, design aspects are very good however, but they are extremely weak in other areas. Compare ADA vs Walstad (see chapter IV). Likewise, Diana is hardly the best scaper out there, we are all weak in many areas
The point is to try and improve holistically. Then you are better able to achieve your goals, and then more importantly, help others achieve theirs.
ADA fulfills a very good aspect, so do many others, we each have a specific skill set that contributes to the entire hobby.
I've had GDA about 6-7 times and it's never lasted for long. I will say I do not know specifically what causes it and why some have long standing bouts with it. I've seen it at several places who have ADA full line ups. Eventually they got rid of it. But so does everyone at some point. I had it in a new set up on a client's 350 Gallon tank. 2 weeks later: gone.
Algae is not exclusive to any particular to any Brand, method/dosing, light type etc. CO2 concentration perhaps.........we see algae in ADA tanks plenty, as well as with EI dosing.
So is it the hobbyists looking to blame things? Or is it ADA's fault? EI's fault for the woes? It's us, not the methods.... they both work for the same reasons and they both add the same things.
