All three combined wouldn't be enough for one roll
Yep but everything except the pH was find.
I've been having a ridiculous problem with pH. It'll be 6.4 out of the tap (and after gassing off) but within literally 30 min to an hour of putting it in the tank the pH is down to an unreadably low level. The crushed coral never made it here in time, and the pH Up I bought at the store did literally nothing to increase the pH.
I did water changes daily to try and keep it the best I could but the one day the two fish and the snail just up and died with no warning. They looked like they were doing fine (I had them for a few weeks) but apparently not :/
