you had a mini-cycle because of you added some LR
. Did you see a rise in ammonia first, and if so to what level?
You have about a 50/50 mix of LR
and base rock. Your tank might
be cycled, but there's a better chance that you don't have a very large population of bacteria yet. Try adding a pinch of flake and see if you get an ammonia reading in a day. If there's no spike to ammonia, nitrite or nitrate you can do your PWC
and start slowly adding livestock (1 fish per month).
Please keep us posted.
