Thanks.So its basically the same thing as running sand in a fuge.I used to use the kent biosediment and half the sand should be changed every year or two.I am wondering when changing if there will be some impact on the bioload of the tank.I guess thats why its safer to have some kind of sand in the sump and a sand filter just for security.I was also thinking of getting an H&S denitrate filter.This will be in a year from now maybe 2 years.I think with this much volume of water plus 2-3" of sand in the tank and some kind of DSB and a sand filter I shouldn't have any nitrate problems.
