That rings a bell. With my outdoor turtle and fish ponds I used a mix that had lime in it and was able to leach it out.
But with the smaller indoor exhibits I used my own mix without lime. I thought portland has trace amounts of lime in it but I'll take your word for it.
Are there any toxicity concerns with cured portland? I know my exhibits cured for a long time before I introduced animals but it's been so many years I can't recall if there were any toxicity concerns.
