My whole tank seems to be in trouble!

[Willba200]

Hi, on Sunday I did a 20% w/c and since then my tank seems to be in trouble. The polyps on one of my corals refuses to come out! Today I came home from work and my large toadstool won't come out. Also I have two duncan corals and both heads have a brown film over them and also have not come out. Lately I have a lot of cyno on my sand bed. I upped my flow and cleaned the bed yesterday but today it has all come back. The only things that are ok is my finger coral and pulsing Xenia . The tank is four months old. All my readings seem fine. Please help as I'm panicking !!

Are you using RODI water or treated tap water?

 

[molliwopp]

Clean fresh regular ro water changes is the cure.

Always use r.o water

All is still the same, although mushroom is out but has gone a different shape and turned to one side . Is this normal?

 

[mr_X]

Did you change your lighting recently?

 

[Willba200]

No I have the same lighting. Getting a little concerned now. Poylps on my othe coral have still not come out.

 

[Willba200]

Ok, I could do with your help on this one mrX . As you know my mushroom is all limp and not to good. Today I took it out of the tank and dip it in some fresh water. It looked as though there was brown jelly on it , so I gently rubbed it off and placed it back in the tank. On a closer look I noticed holes in my mushroom. Is it on its way out and should u throw it? Or will it recover?. Your opinion would be much appreciated . Many thanks.

 

[mr_X]

Do not throw it away. Do a water change.

 

[Willba200]

Have done a few w/c. Do you think it will recover?. Is it possible the brown jelly has caused my other corals not to open. It's been a week now. Got my water tested yesterday before w/c and they said water was perfect. Will do a small change tomorrow.

 

[mr_X]

No. that's not possible. LFS's in my experience test with strips. If they don't, they just look for ammonia, nitrite, and nitrate. Alk could be your problem, and could be ph.

 

[Willba200]

They did not use strips they done it with test tubes etc... They did about 5 different ones and all were good . Although they did say as I have cyno and some algae it can give you a false reading.(this I knew) was hoping they would pick up some thing my test kit had not . So do you think w/c will sort this and hand picking the cyno out.? If it's a bacteria problem will my w/c eventually solve this issue? Do you also think my other corals will be ok?

 

[mr_X]

How long have you had the toadstool? If it's more than a month, it's because it doesn't like your tank.

 

[Willba200]

It's been about a month. After a week it grew a film over it and then it came out even better then before. If it does not like my tank then does it mean I can't keep corals? Or is this one just being awkward? Really want a reef tank and not fish only.

 

[mr_X]

It just means a parameter is out of whack, or flow, or lighting...something is not ideal. Leathers do shed a coating every now and then too. I do not know why they do this.

 

[Willba200]

Done a small w/c today . Will continue with this every two or three days and fingers crossed it all gets well soon. Thanks for your help on this one. No doubt I will be seeking more advice in the near future.

 

[Willba200]

Hi,I now have bristle worms that even look sick! One half of them is pink and the other half is black? The toadstall is now covered in brown jelly.

 

[mr_X]

What salt mix are you using? How exactly are you mixing the water and doing water changes?
