there are also few before and after pics of people using hob fuges too.
heres a thought. If you were to diy a fuge to grow plants with roots. You would get a sub-strait the plants an easily root in. then add stuff to augment the soil to help them a long like you would a planter box or a backyard garden. in that soil you just created for those plants, true sand is a better choice than oolite as the drainage and flow is low in oolite, and its easier for the plant to take root. So Sand is better. Play sand is a better choice aragonite for the same reason but finer grains would be better than large coarse, but would work fine, but is not the method.
The eco system method is full of snake oil, yes, but so are most reef products (or any really) . You buy $500 lights with no par or lux data dont you? Do we really think the New AI is HD?(1920x1080?)
The eco system method is based on the theory of adding live plants to take up exess nutrients and toxins. In other hobbies this method is employed to purify water in backyard gardens that grow food.
It is not a DSB. The system method actually calls for using one specific type of plant too. Adding a skimmer to the system is actually called the Planette method. Neither of these are the Berlin method.
getting a cloudy tank is not the method's fault. youd get a cloudy tank for longer adding an oolite dsb unless you were really careful.
so yea IMO the method works but its based on(now) similar less expensive methods. I wonder that Planette jumped on it years ago at there was no other comparable method and he was a great Spokesmodel with a name. Personally I dont begrudge him that as we all need a paycheck and its more honest than selling diet pills or triton tests to a guy with a 14g bio cube...
After long long research on eco system and DSB I added sugar an oolite with Fiji mud to my DSB in the fuge. its fine. All the tanks I researched that were very old and successful(stable) had a refugium and a dsb somewhere in the system to create a natural stability, Or were cleaned regularly(Paul B).
thats my .02. but im going to change it to .39, cuz you cant buy anything with .39 either.
