Weekly 15 gallon water changes. I have a 120 but my net water volume is 100 gallons. Yours is probably close to that. 30 gallons is overkill.
Stop using PE Mysis for now and only feed fish with LRS or Rod's once a day to start. No aminos, coral food, Zeofood, Pellets (dry food) etc. for now. You can always SLOWLY add these back once you get some stability.
Coral snow maybe two to three times per week Zeozym once every two to three weeks. I personally haven't seen a benefit from doing more often.
Zeobak per Zeovit directions. Don't be afraid to adjust down. Overdosing Zeobak can brown out corals.
If you can break up the Zeostart to twice a day that will help keep a constant carbon source for the bacteria.
Aggressive skimming
Do not let your NO3 and PO4 bottom out! Bad things will happen. Adjust your zeostart accordingly. Don't be afraid to go a few days without dosing Zeostart to get your numbers back up if they go to zero.
I would suggest that the Zeovit system "instructions", for lack of a better term, are just guidelines for a mature fully stocked tank. If you have a tank full of 1 inch frags I would cut the suggested dosing amounts in half. I have found that with Zeovit less is more.
Don't be overly concerned with pH
Keep the dkh stable if you are SPS dominate!!!!!!!!!!!!!!! I think one of the most important factors. I check mine every day.
And now the hard part, be patient!!!!!
