So I'm planning to cycle my 10 gal tank and was wondering if during/after
the ammonia cycle, would I be able to put in some sand? or would it be
best if I waited until I could get the sand and then put it in before I
start on the cycle??
When I cycled my goldfish tank I put in everything except the fish. More places for the good bacteria to grow, and gives everything time to mesh together.
When the fish are in is not the time you want to discover previously unknown spores or seeds are sprouting in the sand, or that the filter suction is strong enough to move the sand around, etc. None of these should happen, but that long wait for cycling is a great time to work out any kinks in your set-up.
