Sweet glad that reactor is being put to good use!
Everything looks good. NO3 is a little high. Do you have a DSB or regular sand bed? If you have a regular sand bed that is about 1-2" in depth, you may want to vacuum the sand. It most probably has high, undissolved nutrients in it and causing your NO3 readings to be a bit on the high side. I would vacuum the sand (in 1/3rd increments) when you do your water changes. So every water change, do 1/3 of the sand bed and so on till you completely have done the sand bed.PH 8.1- 8.3

Yeap, I was going to ask too. Try to cut back on your feedings and amounts. So if you are feeding everyday, go to every other to 3 day to feed. hope this helps and keep us posted.light schedule? and feeding schedule?
