Thanks guys for the kind words, the tank is indeed doing very well. I couldn't be happier with it right now. I've had a few people over the house the last couple of weeks and I think they were pretty impressed with the look and coloration of the corals and probably more impressed with the amount of fish in the tank right now, it just looks like a real reef.
I am dosing the standard Triton Base Elements, 331ml a day. I run an ARID C30 algae reactor filled with chaeto for N and P removal. As far as trace element dosing, I dose daily my own blend of Zinc, Iodide, and Manganese (soon to add Potassium still working that out though). I also dose KNO3 to keep Nitrates around 5 ppm. Every two weeks I add some strontium, and now Vanadium.
I am not targeting anything specifically for color, rather I am focusing on a variety of elements that I feel are important to acropora that are outside of the standard we normally keep track of and just trying to keep them either at a specific level, or if that is not possible (as with Manganese) at least adding strong amounts of daily additions to keep it available for the corals to use.
The elements I have been targeting are Vanadium, Zinc, Manganese, Iodine, Strontium, and Potassium. Potassium a lot of people are tracking too, I just make sure it is between 400-450 ppm. Alk I have been keeping around 7.7-8.3 dkh pretty steady though at 7.7. Ca at 450, Magnesium at 1420. Nitrates at 5-10 ppm (I will reduce my Nitrate dosing if it reaches 10 but try to keep it solid at or slightly over 5 ppm) and PO4 at roughly at 100:1 ratio of N to P so 5 ppm of Nitrate is 0.05 ppm of PO4.
Kevin, yes the PO4 is a little higher than it was last time. But with trying to keep that 100:1 ratio it is probably right in line with what my NO3 was (between 5 and 10 ppm). As you can see from the pictures there is no algae on the rocks or sand.
