That's not a nano or even a "nano". Honestly you probably have about as much money in your skimmer as I do in my tank. But I'm glad to hear it's going well for you. Stability is key.I use Triton core 7, large refugium, two radion G4pro, Large Deltec skimmer, feed acropower reef roids KZ coral vitalizer and phytofeast in a 125 Gallon "nano" tank, my acro are growing like weeds, ULNS BUT very stable parameters agree magnesium is essential I use high flow 10X tank volume through sump and 2 Vortech 40 using WW corals flow suggestions in the radion coral lab booklet. I use tropic marine pro salt
I place the coral and forget them don't move around at all
I have used almost every method and Triton is the most successful followed by Red Sea ULNS recipe
