Using old sand !!

[Alan600]

I'm getting ready to upgrade tanks . I have bare bottom on my current tank but want a sand bed again .

My question is I have some crashed coarl that has be sitting out for 3 months ir so . I did a good rinse add a little bleach to whiten it up .

Do you guys think I can still use it or will it just nuke the tank ??

If you want to use crushed coral, just keep rinsing it to be sure.

I do not think it will nuke the tank if you used straight bleach, if you used one of those bleach and soup combination or fragrance products than I definitely would be reluctant to use it.

Personally I am not a big fan of crushed coral but if you like it that is all that counts.

IMO I would just buy new sand. Using old substrate is like playing Russian roulette.
