Man im not sure. What the ammonia at to start? I think your nitrates should be higher but you do have the skimmer so im not sure. If you wanna be certain, buy pure ammonia and dose to 2ppm. If its 0 in 24 hrs you should be good. I know on my 2 tanks i had a massive diatom bloom after the cycle.
Thanks. I dont have the skimmer running. Just the AC70s with filter floss. No light running either.
