Yes, I did rinse my carbon thoroughly, I originally put carbon in a media bag in my phosphate reactor (thought carbon was probably more helpful at this stage). I even doubled up on sponges in the reactor, that wasn't the cause of the blackness, which didn't start for a day or two after adding the carbon. Plus, I don't think I could have gotten it that black with carbon even by dumping the whole 4L of carbon directly into the tank The smell is amazingly different, there's practically none now, it just smells like a reef tank.

I would remove all the water, rinse off your rocks and start over.

Alright, anyone care to make recommendations for a skimmer? The tank is barebottom, and hopefully will be fairly heavy on the SPS. The biggest chamber I have in the sump is 8.5" x 12", height of 24" to the top of the stand.

In other news, the tank is less yellow than it was yesterday, I added two bags of carbon.

Update!

After doing a ~50% water change, aerating and turning on both Koralia 4s for the past couple of days, this is where we're at:



The water looks great! It's actually clearer than in the picture (camera phone), almost perfectly clear. Woohoo!

Yeah, how's that for a turnaround? The carbon probably helped as well.

It's okay I guess...but I think I like the black water better. I mean, clear water in aquariums has been done so many times before, but jet black water...that's something new. Very cutting edge.

Much better looking!

Tunze 9010 - supposed to be a very good compact skimmer.
SWC MSX160 - too much skimmer?

i was just pointing out that things like this could be prevented. seemed like the product of slightly rushing things. props to the OP for getting things under control.

I am fairy certain something quite wonderful happened in that tank and you just could not see it, kind of like The Abyss.

Update!

I have the sump plumbed up and running, all pumps and powerheads on (two Koralia 4s and a Quiet One 2100 for a return pump). I also got the overflow to quiet down, was very noisy to start with. The phosphate reactor and heater are also online, next up is the RDSB as soon as I find a bit more sand to top it off. I might get the auto top off set up tonight as well, but I'm still tweaking the salinity. I've been seeding the tank with bristleworms and amphipods pulled from my other tank so they can get to work. The water is now crystal clear (moreso than the picture indicates, camera phones only go so far):

IMO, this had nothing to do with the rocks. Marcorocks are bone dry and washed before they sell them. Thats the bad thing with those rocks, is that they are actually dead baserock..

Your problem stemmed directly from the sugar+ammonia IMO. I dont know why anyone would put those in a tank. Hopefully others who have read this will learn from your "learning experience".

I will say, it has made a good recovery. GL

Yeah, the marcorocks arrive pretty clean, though I'm sure there is some dead material in them. I pulled off the crusty bits that I could before adding water. The original intent of the nutrient addition was to promote the growth of beneficial bacteria in the dead rock. I figured that some people begin cycles with some kind of nitrate source (the "cocktail shrimp method") and sugar/vodka is sometimes dosed to stimulate denitrifying bacteria, so it was worth a shot. What I got was a completely anaerobic tank, which may have been a roundabout way of achieving the desired result... the rocks were completely immersed in a soup of anaerobic bacteria, many of which I'm sure still remain deep in the rocks.

PS I should add that marcorocks are great! I don't mean to come across as blaming them or anything, it's all worked out pretty well.

The Marco I purchased was very clean too, but within 12 hours of putting it in water the ammonia was off of the charts. I didn't need to add a single thing.

Another update (this thread might as well be my tank build thread, it's got a catchy title).

Today I got the auto top-off up and running as well as loading the refugium with Chaetomorpha and setting up the refugium lighting. I've also been seeding the main tank and refugium with microfauna (brittle stars, Asterina stars, isopods, bristleworms).

Also, I did my first NO3 test, 0-5ppm. Pretty good. Over the weekend I want to get the RDSB online.

I did not wash my Marco rocks. NEver looked like that. It's good to see you worked your problems out. This situation made you a better reefer.

The progress of this has been really cool to watch. Goes to show what a little patience, simplicity and "riding it out" can do to correct major problems.

Shaping up to be a great build thread!

"sugar/vodka is sometimes dosed to stimulate denitrifying bacteria, so it was worth a shot. What I got was a completely anaerobic tank, which may have been a roundabout way of achieving the desired result..."

It's something of a challenge to get an anaerobic area in a tank with deep sand or large pieces of live rock, how could it be that the water was so deficient of oxygen as to create an anaerobic environment in an open tank?

PO4 and NO3 are probably off the chart, I would have drained and cured in plain RO.

What test kit you use?

How I think the tank became anaerobic: The sugar addition caused a bloom of aerobic bacteria (the water turned cloudy white for about 12-24 hours before it turned black) which quickly used up all the oxygen. The tank only had one powerhead for water movement which was placed deep and created no ripples or anything at the surface, the sump wasn't running, and was at a warmer than normal temperature. Of course there also wasn't anything photosynthesizing.

NO3 and PO4: I used a Tetra test kit... not a good one, but it should be reliable for at least a high or low result, but this came one came out just slightly above 0. I've had my phosphate reactor running for a week now, which combined with the 50% water change should keep the phosphate in check, don't you think?

This is the correct answer


If your tests are good the only thing I would do is think about changing your Carbon and Phosban out in the next week or so. They probably absorbed near capacity levels in a very short time from that immense bacteria bloom.
