I'm fairly new(only a couple years) but that picture was taken around the 1 1/2 year mark. I dose a small amount of aragamilk biweekly. and I drip kalkwasser about once a month. i do bi weekly water changes with RO opposite the aragamilk dosage. The setup is now taken down for the most part. 95% of the corals i own are in my girlfriends aquarium waiting for my 75 to get established. I was mostly into zoas and softies for a while. The 75 will be mostly lps with my zoas i've collected. There is no real secrets.
If there was anything at all, I think the decision to get T5 for my first reef was the best desision I made. Also, having a couple colonys will do wonders for making the tank look alot less like a frag tank. With the 75 Ive learned from my mistakes equiptment wise. I've had to rebuy better equiptment this time.
