I've had my 10 gallong set up for awhile. I've had nothing but issues out of it since day 1. I finally got it going good. I have the 8 week mark written on my calendar as July 8th I believe. My question is: would it hurt to go ahead and do a gravel cleaning or do I need to wait for the full 8 weeks? I have not did anything with it since I put these fancy goldfish x2 in it. I only have those 2 fish plus 1 cory catfish bottom sucker. I have nothing else. I didn't know if it's safe to clean it before 8 weeks or if I need to wait the full 8?
