DSB to fuge, mini cycle? Help me figure this out!

Can adding a DSB using live sand to an existing system cause a mini cycle? If so will I have this issue using dry sand. I cant get southdown or whatever here so what can I use.

My choices are and I would like to know peoples opinions on what they have used and their overall experience,

1) kitty litter - dont get how I can keep it from turnin my tank brown.
2) dolomite
3) limestone - pulverized, pavestone
4) live sand
5) dry sand - What kind and where can I get it. Chicago area

 

i saw 30lb bags of dry aragonite caribsea at petsmart in chicago suburb for $19.99 a bag. i cant see adding dry or live sand causing a cycle.

 

i think adding live sand can cause a cycle in the same way adding live rock causes a cycle

 

Which petsmart was this? I live out in Lombard, I'm gonna check the downers grove on tommorow.

 

the only reason a cycle happens is if you have dead organisms in the rock/sand. If its dry there should be no cycle (but make sure you wash it well)

 

Anybody else? Before I go make this purchase

 

sorry was at work all day. petsmart in algonquin had them for $19.99 a bag when i was in there last week. generally dont go there, but had to get something for a friends cat. happened to check their, very limited, stock of saltwater things.

i also know you can get florida crushed coral in 50lb bags from a place in schaumburg for ~$35.00 if you need it PM me and ill send ya the stores details.
