I'm about ready to give up.

My test kit says .08 is where it should be ideally /shrug

er .06 for iodate it looks like, so i am a bit on teh higher end but not too much it seems

Edit: I'll def. test this again tomorrow on my lunch break. I hardly ever add Lugol's to my tank, maybe once a month.

 

I could be barking up the wrong tree. I was never able to read the Salifert Iodine test results so I never added Iodine to my tank. So I'm no expert on Iodine.

Lets investigate other things.
What do you feed your tank
Does your tank have a lid on it.
Is your fuge lite 24/7, revers or same as tank?
what is in your fuge and how is it?

Trying to help.
"all my water paramaters are in check."
What are the numbers?
SG,Cal, Alk,ammonia, nitirite, nitrate... Basically any test kit you've got.

Did you redo the plumbing when you got the new pump?

What kind of corals were the new ones?

Did you change your lighting recentily? It kinda of kinda of sound like possible UV burn. Fish can hide corals cannot, doesn't explain the CB RIP. I don't know if your MH are DE or SE. If DE check to see if the glass is firmily in place and if SE check to make sure the outer bulb isn't cracked.

 

How do you test for stray voltage?

 

Maybe....Maybe Not. Iodine, Iodate, and Iodide are all different. Additionally, the test kits for I vary greatly in what they measure.

I'm sending Boomer a PM.

 

Wow, I can definetly feel what you are going through.

I dont think it's stray voltage. First of all, did you add anything electrical to the tank lately? He mentioned his tank was running fine and after he ran the carbon and added the three corals, everything went down hill. I also dont think it was the carbon. Carbon is actually helping your rid of whatever chemical is messing with your coral, but it looks like it's in abundance in your water. Carbon is actually a very good thing with almost zero side-effects.

Your tank definetly sounds like it's nuked. Now, I dont think it's the Iodine, although Lugols is extremely powerful. How much did you use?

Was anyone near your tank these last couple of days? Any kids? Sounds like there is a trace chemical killing fish and coral; ammonia or chlorine, chloride, etc. Dont think it's UV, it would have to be extreme overkill on the light and most corals can acclimate to stronger light. I dont think UV burn is the cause as well. It really sounds like someone put something in your tank. I dont think the UV would be so much as to affect the fish. No way.

Someone mentioned to mix a new batch of water and place everything in there... very good advice, take it. Then save your old water and test, test, test. Either mix or buy water from the LFS.

I forgot to ask, are your surviving fish twitching or scratching on rocks? Displaying spasms? Are they coming down with ich? Burns? Let us know.

 

Just wanted to add that you should ABSOLUTELY check for stray voltage (with a volt meter) and add a ground probe regardless of what the problem is. Karma for your losses

 

Completely different direction here. You said

What version of pump did you add? Was it used/new? Did you clean it out before you installed it? Have you tested for metals like copper, lead, zinc. I would put the 20hf back on and check the pump out. The corals you added would not have done this to your tank.

I have seen some water levels that were off the charts and coral and fish survived. There has to be something wrong with that pump you changed out.

 

J: Nah I don't think your barking up the wrong tree at all and I'm quite thankful for your thoughts ! I too have a hard time reading my iodine test kit.

Covey: I'm going to test all my water parameters again at lunch today. I'll update with a full spread in a few hours. I did redo some of the plumbing with the new pump. I used the purple pvc cement on 3-4 fittings and hose clamped a large piece of vinyl tubing to go up to my dispersion rack (a rack of PVC T's to aim the output water) I reused as much of the old plumbing as possible. All joints had a minimum of 6 hours curing time, and the usual rinse in freshwater.

I added the MH lights maybe approx 4 weeks ago, they're running for less than an hour a day at this point. I don't run my UV light anymore, no real need to run it for me. As for UV from the MH's, I'm not sure there. The guy I purchased the MH's from (used) said the whole thing was 4 months old. All I can really do there is take his word for it. Bulbs are SE bulbs.

TinFury: I'll go buy a grounding probe from a LFS today. Unless anyone knows of a DIY method.

Rickzter: I did have some friends over on Saturday, one i've never met before. The other two are life long friends of mine, one of which brouth the new guy over. I think its possible they (especially the new guy) could of poured some beer in my tank or something. But he was never left alone. I did ask my 2 close friends if he had done anything, they said "no way man!" Those two know how much that stuff means to me, so i really do trust what they are telling me.

The surviving fish are 2 true perculas and a blue hippo tang. They all seem perfectly fine. I'd think the tang would have gone south a lot faster than the CB, at least I do anyways. Quite mysterious, it was such a rapid decline too. Thankfully, there are no signs of parasites or the like.

amcarrig: Will do, I'll go buy a volt meter tonight and git-r-done. As for a grounding probe, any DIY types you know of before i get owned by my LFS

ALL: Thank you VERY MUCH! I really appreciate all the help so far I'll update in a few hours w/ an array of water parameters.

 

If you google "DIY Ground Probes", you should be able to find something.
