and here it is everyone! Winter has passed and I finally managed to find some time to set it up...thanks Murray to your input over the web and I look forward to your and everyone's help as the system matures.
I've already encountered the first obstacle: the system's pH is 7.5 and I'm trying to lower it with hydrochloric acid. I managed to get a 9% solution and I'm not sure if this will be strong enough. The water volume is 500 liters, and I'd like to know how much of the solution I should be adding daily. Any suggestions?
