am I setting myself up for disaster?

This may be a bit lengthy so I apologize in advance.I pretty much went against everything I have read and been told by the more experienced Reefers such as most of you all and am waiting for a disaster to happen.
OCT 10TH- I purchased 100 pads of live rock and put in my 75 gallon tank. This rock is harvested in Florida waters and suspended for approximately 5 years off the bed in the attempt to lesson the likelihood of hitchhikers.Then ground delivered never ever leaving it's original sea water. Imagine the cost per pnd this was!
Same day I put in sand bed prior to putting in rocks.
Set up my 35 gallon refuge sump with miracle mud,colupra and proper lighting,skimmer,heaters etc..
Oct 11-12th set up 2 radion pro Leds and 2 mp40s,apex-(sort of)
Within the last 2 weeks I added phosphate reactor and bio pellet reactor,eshopps cal and alk doser with 2 part Bi-ionic.
10% water changes weekly.

At this point as of today I have in my tank-
2 paired clowns
1 sand sifter
1 Blue damsel
1 copper band
1 Blue tang
1 Blue line cleaner wrasse
Pom pom anenome crab
Emerald crab
Porcelain crab
2 cleaner shrimp
5 turbo snails
Small hermits


brain coral
Torch coral
Small frag hammer coral
Small frag xenia
Mushroom rock
Zoa rock (red and green)
3 different leathers
Rose Bubble Anenome!!!!

Perams steady at
Cal 420
Alk 7.5
No2 0
Phos 0
Mag 1440
PH 8.3 8.4
Temp 78-79
Sal 1.024

The kicker is every single thing is doing absolutely great and looks great. Have not lost a single thing except a fish "jumper".

My questions is
"Is this the calm before the storm"!!!
