Here is today's update. First off, no more losses that I can see :jumping: As far as condition of corals, green star polyps are continuing to show improvement as are yellow polyps. Zoos continue to be stunned. Some are half closed and some are closed very tight. At least the half closed...

No luck yesterday finding a copper test kit or cuprasorb. My local fish store is anything but LOCAL and has very limited Sunday hours. The best I could do yesterday was Petsmart and they had neither available (no surprise there). Most of my green star polyps are back; probably 60% or more...

Thanks Grog! I had already done the night water change but have not done one this morning. I'll hold off and let the water age some on this one. I hope you are right about electricity being the culprit. That was my first suspect also, before noticing the blue color in the poly filter. I'll...

Well, I have done one 12 gallon water change so far (tank is 55; sump and refugium are about 10 gallons). I am preparing another 12 gallons now to change tonight, then I'll start water for another 12 gallons in the morning. Plans are to get a copper test kit (tomorrow?) and keep changing until...

More info . . . I also have a poly filter in the sump, which you likely know changes colors as it removes "stuff" and the color it changes to varies with what is removed. The poly filter is turning BLUE, which indicates COPPER! :scared: So I guess that exposed wire on the NEW Rio 600 powerhead...

I am so worried!!! About three or four weeks ago I replaced a non-functioning and very old Rio 600 powerhead that operates the skimmer in my sump with a new Rio 600. Everything was going along fine . . . or so I thought. Yesterday morning, as I was leaving for work, I noticed that the pump...

Birdy, closed loop??? I am having a hard time picturing what you mean by a closed loop.

Hmmm, so how long can they be expected to last with 400 +/- calcium levels? At the rate I am going I'm gonna need to start stocking spares for when they go out!

Yep, they quit spinning. Sometimes I can open them up and get them working again, but after a few times doing this the lock ups get more frequent until they will not stay going any time at all.

I have a total of six powerheads in my tank -- various brands and sizes performing various tasks of moving water. Some of these I have had for several years all performing quite flawlessly. Within the past year, as I have moved from fish-only to other tank inhabitants, I have been more aware...

Thanks for the feedback. Unfortunately the way my lights are wired together I cannot cut the blues on one hour before and off one hour after, as you suggest, but it does sound like a neat effect. Any other opinions on light combinations from others using VHO?

About 18 months ago, before deciding to add soft corals to my at that time fish and live rock 55 gallon tank, I upgraded my lighting from 2 normal flourescent bulbs to a new ballast and 4 VHO 48" 110 watt bulbs to give me about 8 watts per gallon. When it came to selecting WHICH VHO bulbs to...

Thanks for both replies. Regarding light, I am running four 48" VHO flourescents. I checked nitrates 3 days ago and they are at or very near zero on a low level test. I did not test for phosphates. Calcium levels frustrate the heck out of me. I have 3 test kits and get three different...

I am attaching a picture to better show what I am talking about. In my main tank I have some macroalgae that came on live rock added to the tank over a year ago. The macroalgae has spread moderately in the tank, but for quite some time, some of the ends turn white and drop off. See image...

Sounds like spashetti worms are what I have. Just in case, see photo attached.

Yep, I have had one in my tank for about 8 years. I assume that it still works okay.

I have tried to get pictures of it, but it is so small that my autofocus camera does not detect and focus on it. I'll try again with a tripod (might help). What I mean is that it is about the color of an earthworm and has a similar semi-translucency. You can see tiny organs or vessels within...

Beth and others, Thought I would close the loop on this thread. Aparently the scratches were stress related caused by scraping against the rocks soon after introduction. Within a few days they cleared up and he is doing great now. I did start adding zoecon to food as Beth suggested. Thanks...
