good news to report. it looks like I have the upper hand on my tank now and with only a few losses. I still have several large colonies alive and decent frags of everything else.
I cleaned the center port out an it is operating well, as well as did anther vacuum procedure on that center area. My method is working well, but only removes a small amount at a time.
All parameters are good and ORP has been averaging higher each day. I still have a lot more work to do, but I am re-energized when I view the tank so that is a big plus. I also have put a one hour "nap" into the mid-day light cycle.
I believe I have whittled down the possible causes to lack of flow and not enough mechanical filtration. I also have plans for each issue but it will take some time to make the corrections. The great thing is that the water is looking so much better, there are no dinos, and the livestock is perking up. I do think I may have lost my cleaner shrimp as I haven't seen them in a while.
Not sure if that is due to the dinos, overall water quality, or perhaps even predation...I have yet to see the CBS I put in there over a month ago!
