Looks great.
What are you using for phosphate control?
Heck.. what are you using for filtration altogether!?!? hahaha
1 gallon a week in that tank is 33% probrably more after displacement of corals/sand and rock. That is way more than most people change in their own tanks.i cant believe 1 gal/week can satisfy all the element demands from the sps growth in the long term. but good luck though.
