Hello,
Before I first tried this system, I had to hear about people who tried it. For those like me who like to learn and search before to buy, I made a quick search on google to find comments of people who use this system.
Here is what I found for now:

Note: people who tells about there experience on those post have beed using the full system: tri base pelletized carbon, bacteria, red torpedo canister, ph adjustment rock and probably trace element block and metal gone.
You do not have to use all that. Actually, all you need is the carbon and the bacteria for this filtration system. other goods are use to replace additives.
Comments about those products are not many but I hope it help. Maybe you can reply to those post and ask how things are doing at this time.
regards
