How's it going? I went to hope depot to get some sand substrate for my chinese softshell and they were out of playsand. I asked the kid who worked there if they had anymore in stock and he gave me a bag of quickrete all purpose sand and told me it is the same exact thing. Is this an ok substrate for my softshell? I tried washing it for a few hours and it seems muddy. Any help would be appreciated.
Take care,
Tony
