Ok last deep clean I put in all EE. Had a hard time with humidity, even with the EE, 3 moss pits and 2 tropicairs. I did a deep clean the other day and lost 5 crabs. I am so bummed about this. I truly think it has something to do with the EE and humidity problems. My questions are to all members who use EE as a substrate. 1. How long have you used EE as a substrate? 2. How often do you deep clean? 3. Have you lost any crabs since using this substrate? If so how many? 4. What are your personal opinions on EE?
