Uh Oh! What happened

[AWD]

Uh, something happened to my tank last night. The parameters were good. The fish were doing good. Well, Now 18 hours later the water is GREEN. The fish don't look good. The colonial anonomes are sucked in. All the snails have fallen and are on the sand upside down. The crabs appear to be drunk. Even the clownfish moved to the other side of the fish tank (FOR the FIRST time).
Is this a crash? What do I do?

I'd start doing waterchanges and running carbon.

 

[AWD]

Any ideas as to what caused this?

Give us something to work with man. We need to know about the tank, water, livestock, time up ect... Give us all the info and we will give you many ideas to what the problem could be. Get on those water changes and run the carbon. Rince the carbon often as to keep it from clogging up.

The tank size is 125 gallons. It has been setup and running for about 9 months now. The parameters have been excellent for most of the time. I don't have any corals, but I do have colonial anonomes. I have 4 fish and a peppermint shrimp. I have two mushrooms. I began dripping Kalk about two weeks ago. My calcium level has not changed at all(That's another question). The alkalinity is around 10 (german) the PH was at 8.2. I checked it just barely and it is at 8.4. Last night before the sudden change I did increase the concentration level of the Kalk per liter of water to a Tablespoon for Two liters of water and 20 ml of vinager. Right now I am running Carbon and I ran out of salt so I'll have to wait until tommorow. The fish are still alive, but don't look good.

How do you dose your kalk, do you use enough to satuarate the ro water then let the excess settle out befire dosing? Not that this would make the water green. Sounds like something spilled in the tank to me.

and 20 ml of vinager

Your adding vinegar directly to the tank, Help me here everyone, but I thought that was a bad idea?

As long as the Kalk, water and Vinegar are mixed prior to being added to the tank there is no problem there. I use 30ml of Vinegar to the same proportions your mixing and only good has come of it.

Got any Caulerpa? If so, sounds like it went sexual.

 

[henkelsfamily1]

Just a thought. If the Kalk is not in solution and you add Vinager without vigeriuos mixing, would not the vinager spur a algae bloom. I think that I read that somewhere. I too use aprox. 100mL of vinager to my 3 gal of topoff ( 3 tablespoons of Kalk per gal) with no ill effects but I mix the hell out of it.

Look at the caulerpa! Has it lost its green color? The exact same thing happened to my tank when a light bulb over my caulerpa went out. It went sexual and my whole tank turned green. The calurpan will be clear to white in color if this is what happened.

I mix the Kalk and the vinager very well. I let the solution sit for a couple of minutes then I add the water and let that sit for at least four hours usually much longer. From there I let it drip it usually takes about 3 hours to finish. Do any of you know why the calcium level is not rising at all? Or maybe my test kit is bad? It is old and it made by Red Sea.
I do have caulerpa but it isn't that thick. It grows really slow in my sump and in the tank I constantly pull it out.
