Thanks so much for the advice. For the comments that you folks made it makes me quite sure that it is dinoflagellates. Here are some of the things that I have observed in my tank. It seems to be less after the lights are shut of over night. Little pieces tear of and float to the top(air bubbles). Although it looked a little different and it might of been a diatom bloom there was a fuzzy brown growth on the rocks that had lots of bubbles in it, but that growth was short about 1/4". I am not sure it is related, I guessed that it may have been diatoms. That stuff also really responded to the MH lights and had tons of bubbles. It didn't do much under the actinic lights (420 and 460) About the last photo it was taken shortly after the MH turned on and only one day after I had syphoned the stuff of the glass. Also it is in the highest water flow in my tank.
Today it seems a tiny bit better. I adjusted the KH or carbonate hardness. It is a new tank and I just didn't think I would be short so soon with new water, but it tested at 90mg/liter so I added the max it said on the instructions 1teaspoon to 40gal. once per day. I now have shut out the lights. I also use prime.
A new question when putting the lights back on how much should I start with. I have actinic and MH. on different timers.
Thanks and I will keep posted.
