That is what I thought too.....dirt+water=mud....But it isn't like that if you set a dirt based tank up correctly. The sand or small diameter gravel you cap the dirt with will help keep the dirt in place until it become water logged. Once the dirt is water logged and starts its life under water-it stays in place......
When I dig up plants or replant-I will get dirt up in the water column-but within 10 min or less the water is crystal clear and you would never know that I had a mass amount of dirt floating around.
All my tanks are dirt based and all my tanks water is crystal clear all the time.
Go to my album and you can see some pic of all my dirt based tanks
