Mass algae death

[wvned]

Over the weekend all of the algae died in my tank. It is a grey blizzard in the tanks. I have no idea why. I did nothing new, Jill swears she used nothing cleaning in the basement. I didn't recognize what was happening and was gone yesterday on a road trip some of the day to take Lucky to Jeanna. Then we got company. Nobody was even in the basement most of the day yesterday.

The 75 that I let algae go wild in is a grey desert. The Coraline is gone. The large humps of chaeto have dissolved. The poor filefish are living on the moon now.


The only thing different I can think of was a switch to Aquaforest salt. I have been removing some of the crushed coral on the 240 because I thought I had too much. Maybe 40 gallons of water made with it has gone into the system replacing what went into the trashcan while I siphoned the sand out. I can't see that doing anything.
I put some carbon in last night. The only thing I could think of. Too little too late at this point.

Have you ever seen this before? I am not sure what I am going to do at this point.

even the glass is easily cleaned now except for a few small spots

Did you dose anything to this tank? What salt did you use before?

Also which aqua forest salt did you use?

The sea salt seems a little low in Ca

Also I know many acros use iron. Do you have the ability to test that?

This is very strange

That is weird.

No dosing of anything new.
Red Sea Blue Bucket.
Aquaforest Reef Salt.
I do not think replacing 40 of 650 gallons during some siphoning is going to make much of a difference though.
My parameters come from dosing. I do not do water changes. I simply use NSW to replace tank volume when I do anything that is going to lower the water level a lot.
I have a RODI vat and a NSW vat. I plug the pump into the vat I select into a Hydros outlet and let it fill the tank while I work.
I let the dirt settle and pump the water back to the vat. I lose a little, a few inches in the vat.
I have used 10 brands of salt in my system. I never had it make much of a difference.
I add Ferrion to my tank. My iron always tests high.

I once used fluconazole on my tank long ago. This die off is similar to the one that caused.
A few clumps of chaeto ( it's really pretty growing in mounds on the bottom) and halmadea are left. They look sick but might survive.
No animals appear to be affected.
Go Rox .8 carbon. I do not have the ability to do a large enough water change to matter anymore. 160 gallons or so. ~20-25%

I am sticking extra wave makers in the tanks to raise the stuff and get it to go down the overflows. The skimmer is removing it. I put a mesh filter sock in but it isn't catching it.

Good luck

Many algae have similar reporductive modes like the calurpa you had reproduce last month. (If I'm not mistaken, Halimeda is also a single multinucleated cell like calurpa.) It sucks they all did it at once though.

 

[mellotang]

Temp swing?

 

[kfisc]

Bummer! If you have any snails, how are they doing? Baffling.

 

[wvned]

Temp swing?

None according to the Hydros graph

I saw the normal ones around the top of the tank this morning.

Ya
but even the algae on the glass?

I need to get the gook out and then survey things.
All 3 tanks are affected. All of the macro algae was in the 75 in the fish room.

 

[jason2459]

Never seen that before. Especially effecting the coraline too.

 

[wvned]

What ever it is. It settles to the bottom. Jill is helping me and we were siphoning it out of the 240 with a gravel tube. Less gook is always good. We filled a brut can again. Tomorrow I will pump it back. It plugs felt socks fast and passes mesh ones.
The 75 I can siphon into a sock in the sump.
I have a Maxijet I fitted an 8 inch CPVC pipe too and I am blowing it off the corals. The coralline may recover. There is still a pale purple color to it under then gook though it is gone in places. Even the coralline on the glass scrapes of easily.The band I couldnt get off along the bottom came off.
It has stopped getting worse and I even found some caulerpa that looks alive in the back with a ball of chaeto.
Perhaps new carbon tomorrow.

You accidentally discovered the bacteria based algaecide that Vibrant pretended to be.

That stuff is horrible. I believed the hype years ago and the negative affects on corals was depressing.

Yep there was a big Algaefix thread on here which I remember contributing to. Taricha on R2R proved Vibrant is the same algaecide as Algaefix. Scumbags.

Hmmm, I used Algaefix and did not have a negative affect on my corals???? Different dosages maybe? It was so long ago I don’t remember the dosages.

I used Vibrant a long time ago. It did what it was supposed too. I never used it regularly though long term.
There are so many threads in forums about reefing where 2 people do the same thing and get opposite results. I no longer have extra brain capacity to wonder about such things.

I just put up an extra pump blowing on the rocks in the 75. I changed the carbon too. This too shall pass.
The snails came out when the light went off.
The extra pump blew the chaeto ball out from behind the rock and the file fish was hiding by it as it moved around the tank. I love watching them.

After using Algaefix, I never got any film algae on my glass for more than 5 yrs. I've used Vibrant as well (still have both bottles), but neither hurt my corals that I'm aware of.

Back to you, do you happen to dose hydrogen peroxide in any way? Your algae wasteland picture reminds of when I used to lower the water in my 20 gallon and spray all the algae with H2O2.
