But the walstad method needs a lot of fine tuning and understanding of what nutrients/plants/lighting to adjust to cope up with algae, else you'll have a tank reeking with algae.
The shrimp method is good, if you plan on leaving your fish tank in the basement etc for 2 weeks and not plan on entering it for the duration of the cycle. I had mine in my room by the bed side and was a little planted initially. At the end of my first week, even with 3 dead shrimps rotting away, i had less than .25ppm ammonia, 0 nitrites & 0 nitrates. But i guess the plants were eating up the ammonia. And my room stunk so much that i felt feverish sometimes!!!
At the end of the first week, I threw the shrimps and bought myself the ACS ammonia, which is just clean, fast and easy. I also planted it heavily. The roots of the plants have root nodules sometimes filled with the beneficial bacteria and so it greatly speeds up the process.
