I am convinced it's my lighting and I have tentative plans on trading in my LEDs for a 175 watt Hamilton halide fixture. My LEDs run 9 hours at roughly 30% output. I've played with them over th epast year running them anywhere from 70% to 30% with the same results. I can't seem to bring out great color or growth in my current setup. I've seen some growth, but having this light for almost a year now and seeing images of peoples growth in 3-6 months time, I am convinced something is off. Here are my latest test results: Calcium: 430 Alkalinity: 3.7 Meq/L or 10.3 dKH Magnesium: 1600 Salinity: 1.027 (1.025 after a water change) Temp: 78 Nitrate: 0 Phosphate: Unknown (don't test) pH: 8.15 Is magnesium my problem? I feed every other day and only feed a pellet or two at a time (what my clown can eat at one sitting). It was brought to my attention that perhaps I am not feeding enough and that is a reason my colors and growth aren't maximized. This tank hasn't ever had a hint of algae since it cycled a year ago and that was only a diatom bloom. I don't run a skimmer by do have some carbon and GFO in a filter bag running through my HOB filter. I've posted before that my soft corals don't grow, at all and we've concluded that it is likely from a lack of nutrients. Should I dose amino acids and feed more? My birdsnest coral has been my most successful grower but in 7 months, the growth is pretty unsubstantial compared to what I have seen with others. In 7 months: This: to this: This: To this: In 3 months: This: To this: My Candy Cane has split from 2 heads to 4 in 10 months. My zoas and mushrooms have stayed the same for 10 months too. I fragged these 7 months ago: This is them now: 3 months ago: Now: 3 months ago: Now it looks almost identical. A little more green color and maybe another branch or two, but it hasn't even begun to encrust. Same with my monti digitata.
