Hey guys thanks for the expert input!
1. I'm slowly going to raise the sg up 1.026 over the next few days (stating today with the water change)
2. Must have had a bad reading on the NO2, it now shows zero.
3. Feed the LTA two nights ago. Typically try and feed it every three to four days.
4. The 150 gal tank has been running for about three months. Most of the rock and sand where moved over from a 75 gallon tank. Along with most of the livestock, although the nem has only been in the tank for a couple of weeks.
