Are you not concerned about proper mixing of salt?Not being a pro myslef, but came up with some flags at your process in my head.First the salt being fed after the sand is in.I know in displays you need to pre mix to get more of a "dynamic" result w'proper PH.Wondering how long the salt will need to be in the system before it properly mixes with the sandbed as opposed to having freshwater pockets in the DSB? Also arent you concerned that the system would need to cure before housing any "easy"corals?It sounds as if you know something that Im obviously not aware of.Do tell
