I have a 55 gallon with 3-96 watts pc's all 50/50. I am tring to get the readings into check, so they may be a bit high, but compared to what they were. Phos .25, Ph 8.5-8.6, Alk hard to read to exacy the range but seems to be normal. Nitrites and Amon are 0. Nitrates long battle to get around 10, Salinity is in normal range. I feed all soft corals, like shrooms, leather, and zoa's the bottled stuff for filter feeders. I also add bi-weekly trace additives with iodine, calcium, mag etc. But they all seem to be really washed out, there is even a rock anemone that was bright sage green and now he is almost tranluscent green. What else should I be doing, adding or cheching for? I do have lots of carbon added to the sump to help try and get my numbers down could this be too much carbon cleaning the water too well of my feedings?
