    This is my second tank. It has been running for about 3 years. The anchor coral has been in my tank for about 1.5 years and had been growing nicely. I've had the BTA since April this year and looked to be getting larger. I had the cynobacteria before changing bulbs. I thought they might have been the root of the problem. Before changing bulbs, both the anchor and BTA were doing good. The new halides I put in are the same as what I took out. The vho's I had before did not have a name brand on them, so I know the vho's I have now are different. I've been using instant ocean salt. I have the 48lb bucket and am down to about 5-10lbs left. I use a hydrometer. I see your shop is on Commercial, what are you close to? If I brought in water samples, about how much would be needed?

    I have a 75g tank with two 250w 20k pulsrite mogul bulbs as well as 2 URI Aqua D-light vho actinic. The halides are about 2 months old, and the vho bulbs are about a month old. Since adding the new bulbs, I have notices that my anchor coral and bubble tip are not as big or as open as they use to be. Also, only a few of my zoas have been opening. However, my dersa clam seems to be doing well. The zoas are mid to high in my tank. The clam, bubble and anchor are all low. Before replacing my bulbs, I was starting to get a carpet of cynobacteria. I changed the bulbs hoping it would help that issue. Since changing bulbs, it has gone from velvet carpet to a stringy mess on my rocks. I have the dip test strips and my nitrate and nitrite are both at 0. Alk looks to be 180ppm and ph between 8.2-8.4. I use ro/di water, my filters are about 7 months old. I do 20gal changes once a month and go through about 7 gal a week in top off. Are there other tests I should be doing, or something I might be missing? I'd hate to lose my bubble tip or anchor.
