Even in my fairly high nutrient tanks, I've found a significant difference with daily dosing of AcroPower. At one point, I noted that two pocilipora were not colored up as they should be. I recalculated the daily dosing amount for that tank and within two weeks, the flesh colored up to the bright green it should be and the polyps were significantly more extended. This had the additional effect of increasing the rate of growth of the colony. I do spot feed the entire system on a daily basis, usually around peak light. I turn off the return pump, skimmer, and the powerheads while feeding. Once I note that the LPS have consumed their food (if they're being fed pellets, mysis, or anything else significant), I set the powerheads to feed mode (a 15 minute cycle). When the feed mode has completed, I turn the return pump and skimmer back on. The rate of encrusting and growth has increased significantly, and the color is excellent on all the corals. Once a week, I'll add in RedSea Reef Energy A+B.
Daily feed consists of:
*) Fresh salt mix
*) ReefBugs
*) ReefRoids or CoralFrenzy (powder)
*) Polyp Booster
*) AcroPower
*) either TropicMarin Zootonic or TropicMarin Pro-Coral Phyton & Pro-Coral Zooton
All are in small doses, with the weekly recommended feed rate broken into smaller daily feed rate sizes.
When I target feed LPS, Rock Anemone, and MiniMaxi Carpet Anemone (typically 2X-3X weekly), I'll vary between frozen mysis and PE Mysis Pellets. If you haven't given these a try yet on your LPS, I would heartily recommend it! I've never seen a reaction to a food like the LPS, et al. react to the PE Pellets. Tried it out on a whim with one of my local LFS friends and we were both blown away by the reaction of the LPS, et al. They're readily available on Amazon if your LFS doesn't carry it. Pick up the small bag (56g) as a test to prove it out to yourself for less than $10. Even my tubastrea go crazy for these pellets.
