I'm a few days away from this, BUT after your fishless cycle has completed and it's time to do the 90% water change - is it okay to vacuum the gravel or should I just leave it alone?
I don't think it's a problem either way, but any reason why you would need to? I can see doing this if you used fish food or dead shrimp as an ammonia source. Otherwise, not sure if it necessary.
