0 nitrites
0 phosphate
temp 77.7

If you think you over dosed iodine, you need to test your iodine levels. If you don't test for iodine, you shouldn't be dosing it. There's enough iodine in your salt mix. A lot of corals have very bad reactions to iodine. I'd continue doing large water changes and take the advise of the tech support you called.

+1 to sid's post. Water changes are what is needed and never dose anything you do not test for. I would do this way before dosing yet another product. Water changes will correct most errors like this. Feel safe to do a 50% water change every 2 days for one week. This should correct the problem and get your ALK up a bit too boot.

What salt are you using?

...thanks got some water making now....does the issues i described sound like iodine OD

I agree with boosting your ALK. Your Ca and Mg seem fine... just watch you pH when dosing Alk. Just as an FYI... I used Lugol's from BWA with great success. I hardly ever follow the listed directions on any product. I start at about 25% of what the product says on its label and adjust as needed. Lugol's is very powerful and has the potential to do more harm than good if given the chance. Try dosing 1 drop per 50g every 3 days and adjust to your liking from there.

It does show some signs of OD of Iodine... more or less the fact that the tanks "normal" level that it has been at was changed very quickly. It needs to be over time.... it's almost the same issue some people have when they run a tank or tanks with high Nitrates and then in the matter of 24-48 hours introduce a reactor or some equipment that reduces the presence of Nitrates and ammonia..... some people dont realize that all fish, corals and inverts adjust to their surroundings and when something changes at a fast rate the results aren't always positive. Using NeoZeo from BWA it states that after using the product for a week or two the consumer may notice a little retention in some of theire LPS and SPS due to the presensce of ammonia and nitrates rapidly reducing. SPS like to feed on some of that detrius and floating stuff. Once its gone they need a new source of food. It's kind of hard to explain but I hope I got the point across in this small novel that I just wrote.

This is all you have done right? There were no power outages or contaminate that may have gotten in the system? What type of lighting are you using and how old are the bulbs?

Yes, Iodine overdosing can cause the millie to bleach out and/or RTN. It is a disinfectant and is toxic. It was never made for the hobby and I don't understand why LFS sell it to be honest. I guess for dipping new corals in.
Most people that use it have a pretty good understanding what it can be used for in the hobby but it was not designed to stimulate growth in corals or improve coloration.

thank you very much for all the response.....lights are about 8 months old ( 2x 250mh 2xt-5)....should be fine.....that was the only thing that had changed...i would consider it more of a stn.....i think i will just keep a close eye on them as well as do a 40gal water change....on the main colony of sps effected i see the largest bleach spot is about 1/2"....it looks like the skin tissue has just lost color....no peeling or flaking of skin....and i can still see all the polyp where the white is..

OK, I sure hope it turns around quick. Just keep doing those water changes as i suggested for a week and you should get things back in order.

For the future, most light to moderate stocked reef aquariums don't need dosing at all of any product, if weekly water changes are done at 10-20% with a good quality salt like TMPR.

 

[justforfun]

ya i use salinity...i think i will start tryig that a 10-20% every week(sunday)

What salt is Salinity? Is that that new aquavitro salt? I have been seeing problems with it if thats the one.

When you mix this salt are you finding a lot of precipitation? White residue on the bottom and water not becoming completely clear?

Water heats up very hot after adding salt?

 

[justforfun]

you just have to know how to mix THIS salt....we have contacted seachem directly .....they say add salt very slow 1 cup every 5 min.....slow drop in......once all salt has been mixed literally rub the buckets edges inside to get residue mixing.....the only time when it gets hot is if u messed up when mixing salt.....seachem wixes there salt in the morning and uses before the end of the work day.....i just mixed 40gal of the salt last night.......crystal clear this morning.......MIX VERY SLOW.(thinking about making a sand clock for pouring the salt in..

 

[Frankie]

Exactly my point justforfun. many people are adding this new salt too fast and it is causing problems with there systems. Personally, one cup every 5 minutes is ludicrous. What a friggin waste of time. This salt cannot be that good that it is worth going through all that.

My other problem is they do not inform the user about this problem. there is nothing in the instructions or labeling that is helpful either. So people are just tossing this salt in and blowing entire batches from precipitation issues. According to Boomer anything that precipitates will not go into solution. Ever. This tells me the salt is garbage then if this happens.

Now here are people that do not understand what that white chalky stuff is and think it's normal. There systems are not getting the proper levels of the needed elements and are slowly killing off their corals.

Hmmm, I wonder where they got that idea from

 

[justforfun]
