When a soil based tank is setup properly-using enough of the right species of plants-On the correct photoperiod using the correct color temp lights to support plant growth-the water is safe and as the plants grow will function as the filter/bio-filter-Then along with water changes-all livestock should be safe.
The soil based is as close to a natural ecosystem that can be created in a closed system. Its all about balance......Everything has a job-working together to help make a safe environment. But its still a closed system and will need care-The more mature the soil based the less care it needs-provided that you have balance....
When I set my soil based tanks up...I add all my livestock the same day....Fish, shrimp and snails....they have a job to do....lol....
