Ive had this HM for over a month in my 90 gallon tank and its been doing great. I do regular water changes of at least 10 gallons every week or two. Nitrate and Nitrate are 0, Alk is 200-250, ph is about 7.8 (been struggling to up it), ammonia 0, temp 78. Light is a SunPod HQI 2x Metal Halide Light Fixture - 150W - 14,000k. Ive tried different spots in the tank, from 6-8 inches under the surface to over 12. Also alternating current. Keeps shrinking up. Had it higher up the tank and just moved it down a little. Check out the photo. Would appreciate any help from all you pros. Thanks...
