Fin Rot, and it's my fault

This is going to be long, but I need to tell the whole story so you can understand the situation. Please read and advise.

Hi there. This is the first real problem I've had in quite some time. My tank has been battling red planaria for some time now, so I decided that it was time to rid of the problem. I used Salifert's flatworm exit before to no avail, so this time I raised the dosage. I siphoned worms before, during, and after, and changed 4 gallons of water out on my 55 gallon immediately following treatment, and 7 more gallons a few hours later. I also added some carbon to my sump.

This particular tank has been running for almost a year, but most of the rock is from my first tank and is almost 4. I have a tomato clown and a yellow tang and various small softies, lps, and polyps.

After the treatment, my critters started showing some signs of distress. The clown seemed fine, the tang was breathing just slightly harder than usual and all the corals were clinched up. I consulted Marc Levenson on RC, and he suggested some sort of ammonia remover. Well I didn't have any on hand, and the local pet stores were closed so I ran to wal-mart for the cheap ammonia, chlorine, and chloramine remover. I dosed accordingly and tested my tank an hour later noting no ammonia reading. Before I went to bed, I noticed that my clown's fins looked a bit frayed, but it was late and I was out of options.

Today after work, I arrived home to my corals looking rough but better, and my fish showing worse signs of fit rot. I scrambled to PetSmart (I figured they'd have every medication and additive in the world) and grabbed some melafix, as that was the best option that they had. After speaking with Melev, he said I needed to get some water forced through the carbon in order to have it be more efficient, so I hooked a powerhead up to the open end of a floss bag of carbon. It worked great, but the carbon wasn't rinsed well, so now my tank is black.

I then decided to try and quarantine my fish and treat the frayed fins in some fresh water using a sponge that I keep in my sump for such an occasion. I couldn't catch either of them, and I didn't want to stress them any more than I already had, so I treated the whole tank with Melafix. Of course the corals closed back up immediately, but have since recovered. I'm now running my display with no carbon and no skimmer (per the melafix instructions).

Can someone recommend another water change, continuing to medicate the tank, running carbon, or turning the skimmer back on?

It's been so long since I've had any issues like this that I don't know how to react. Please help!
 
...oh and current parameters per my cheap test kit are:

pH 8.0 (lights have been off a while, but it's never that low)
NO2 none
NO3 none
NH3/NH4 .25-.5 (From the worms I assume)

I just finished the tests, so I'm going to do another water change before bed. Any other suggestions will be great.
 
I've used flat worm exit on my reef only tank. It works but they come back. My corals were not to happy. I hate that stuff and would never use it again. Always rinse carbon before use. Put some filter floss in to remove the carbon. Planaria are unsightly but really don't hurt anything. I started to skimm again on my nano reef. Seems to have reduced their numbers. Good luck. I guess you just have to wait and see.
 
I rinsed the carbon, just not good enough. It's not the flatworm exit that causes the problems either, it's the toxins from the dead worms.

This is my second go around with Flatworm exit, so we'll see if my upped dosage has any effect.

Thanks.

Oh, and after changing some water, things seem better today.
 
I guess the only way to find out would be to dump flatworm exit in a tank that doesn't have any flatworms and note the effects.
 
I am battling fin rot on my tang right now with melafix... I don't know what caused it but it started last thursday and by monday night his fins looked horrible. I have done 2 doses with no skimming or carbon. the fin rot seems to have stopped progressing and everyone seems happy including the corals. I turned on my skimmer last night and it overflowed in less than 5 minutes. So I will keep dosing 'til this weekend and then do a double water change and run some carbon b4 turning on my skimmer
 
If it came out of nowhere, you may have some water quality problems.

My water quality problems were caused by the fact that I had 10s of thousands of dead flatworms in my tank. I doubt that the fin problems on your tang were caused by nothing. What type of water do you use in your tank?

I haven't had any issues with dying fish (other than carpet surfing) in well over 2 years. This is such a pain. I just hope I can get him through it. I've had this guy for a little over 2 years, and my clown for almost 3.

Here's my poor guy. He's doing a bit better, and he's eating well, but I'm not sure we're out of the woods yet.

I feel for you... I have not had a death since I got into the hobby back in January. I don't want to take over your thread but here are my tang pics. I use rodi, with instant ocean... my parameters are good (sg. 1.024, ph. 8.2, ammonia 0, nitrites 0, nitrates <5, phos. <.05 alk. 10.6, calc. 450) but I did have some big tempurature fluctuations right b4 i noticed his fin deteriorations.

I read your thread earlier. 4 degrees is a decent swing, but I'm not sure it's large enough or severe enough temps to cause huge problems. Your tang doesn't seem to be in too bad of shape. I would make sure he's getting some good vitamin/selco supplemented food, and see how things go. Good luck.

I guess I may even be in a better boat than you are since I know the cause. I have made a few water changes over the past couple of days, and I plan to make one more tonight attempting to get all of the toxins and ammonia out of the tank. As I said, I like my chances as long as the fish are active (within reason) and eating well. If things don't improve over the remainder of the week, I will take the actions neccessary to move the tang to quarantine. I don't currently see a need for the clown, as his fins have healed up nicely, and he's acting totally normal. Good luck with yours.
