I started to dose like 3ml a day on a 202 gal and slowly ramp It up to now 7.5ml over a two week period.
I see great improvements in the last month, better color and PE.
Growth is not coming from AA, you still need to feed your corals in a moderate way some other key products.
I also using potassium as many reefers don't, but please test before you dose potassium, level needs to be around the 390.
I'm also making three different blends from,
1) Oyster feast, Selcon, Reef Chili, Garlic extreme.
2)R.O.E, Selcon, vitamin's.
3)Roti and Phyto feast, Selcon, Reef Chili, Garlic Extreme.
All the blends I keep refrigerated and dose in the sump.
Always dose in a high flow area btw!
I feed every other day 1 blend only 10ml in the evening.
One more thing, PLEASE feed your AP during the day when lights are on, corals don't intake AA during the night.
Scott Fellman did a cool write up about feeding SPS.
Follow Scott on his blogs and learn some along the way.
Again make sure your system is in balance as in stability, you can spend all the money in the world, if your tank isn't balanced it just a waste in most cases.
