little if any polyp extension...(really not zeo realted)

[golfish]

Guys,
I'm at the end of my list. I've treid everything I know of since starting this tank (1/15/04) nothing works. I'm still having bleaching issues with some corals (way before Zeovit) most have little if any polyp extension. I have seen better color and 10x the growth using Zeovit but lots of corals just wont stop turning white, their not dead, just white. The next thing on my list is to start over with fresh rock.

My water param are just fine, I have tons of flow, good skimming. I've replaced my Radiums with new ones, replaced the Radiums with 10k XM's, I've tried using glass in my pendants, I've taken the tank apart and looked for lost toys that I thought maybe my kids and thrown in, check for stay voltage, replaced all water treatment filters, cleaned and re cleaned all pumps and equipment. Removed all the sand from my main tank and replaced with Starboard. I just don't know what to try next, maybe I'll take my fuge off line and remove the sand in there.

Mark, help is on the way , plz. tell me you're net vol & current zeo-dosages. This ZEOvit is just the ticket for SPS, I guarantee itBob

I know this idea is way far fetched (but it actually happened to me a long time ago). See if your heater touches a hose (or cable) somewhere and slowly melts some plastic into your system. I couldn't actually see it, but feel it when I ran my hand along the hose. Or, something along those lines....maybe there is some toxic element released somewhere.

WOW, Gary, you Sci-Fi guru you Bob

I agree that something somewhere release agresive "material" in the tank.My suspicious will go to the fresh water what you use for salt make up.If anything toxic was in aquarium with regular weekly changes that will be removed or diluted allready.
One of my friend have similar situation,he can not keep hard corals ,he have soft corals and fishes without problem but any hard corals become white with no polips expresion and die,very weird situation.

Hi Mirabel, did he discover the problem? Begin a new tank? Thnx, Bob

I might be stating the obvious but when you went from the 20k Radium to the 10k xm did you go through a long reaclimation period. I don't know par on a radium but would think it to be quite low as I've heard they are actually even higher kelvin rating than stated. 40k not 20k or something like that (not actual numbers but you get the idea). The 10k xm has one of the highest par ratings of any bulb I think. So I wonder if going from one of the bluest bulbs available to one of the brightest highest par (orange-red spectrum) bulbs available has done this. Are they sloughing tissue?
Good Luck,
Chad

Hi Bob
No he did not find where is the problem jet.He had ecosystem filtrations when thing start downhill for hard corals,now he have zeovit filtrations but same issue.I dont think his problem have any relation ship with filtration.We check salinity,temperature,proper coral positions,change salt,better circulation,metal parts,ca,kh,ph,po4,no3...I dont know what we dont check.Now on my recomendation he start to use NSW and we will see if there will be a progress to better.He still dont have RO and use tap water ,where I think his problem come(from tap water),I will send him ro for few weeks.BTW I use tap water too for 7 years without problems but I think he probably have some weird water pipe or something related with home water supply.
I send him hard corals what I propagate and in few days they are white,he return the damaged corals back to me and they recover in week or two.I never saw anything similar in the past,unbelivable situations.Every soft corals are in perfect shape,fish are perfect,hard corals die in few days,every hard corals-euphillya,caulastrea,funghia,montipora,acropora,seriatopora...everything what have sceleton.With salifert test kit all parameters are perfect,he even send water to profesionaly analyzes and they find nothing (no coper,aluminium...)

Mirabel, it's either his water source, or the zeolite quantity or flow-thru speed. One other thought is if he's using too much carbon or using carbon in a canister filter. Be sure that you have him follow the new ZEOvit guide or he can post here for advice, or thru you. thnx. Bob

[bluereef]

Is not zeolite IMO because he had the same problems months before zeolit(he had ecosystem with skimmer and activated carbon).He also stoped using zeostart month ago but no change and he also use recomended carbon quantity and pasively in the sump.
Beleive me this is weird things,corals what he cant keep with the few 1000 $ in equipment I keep in 300$ aquarium with internal sponge filter.
Sorry Golfish for stealing your thread but I think that you have similar weird situation.
Sometimes there are issues which can not be solved easyly and are above comon reef keping knowledge what we know(so far).

I'm leaning towards something toxic is getting leached into the tank. I've cleaned out everything but the fuge. I'm going to redo the tank again in a few weeks, removing all the sand and turning it into a grow out tank. I'm also going to replace a few pumps that need replacing. I'll clean out the sump real good. I've been a reefer for a long time, I've never had a problem like this before.

Bob, Net volume is 150 gals. I dose 6 drops each, Bak, food, start, AA and P. Iodide twice a week. I try to dose food, AA and Iodide once more during that week. Run 1 liter of carbon and 1.5 liters of Zeovit in one of Madisons reactors.

Hi Mark, thnx for your update. A couple of situations stand out in my mind. First, as Chad eluded, was photo burn from new MH--maybe try raising these an inch or so higher or decrease the photo period by 2hrs. Your carbon dosage quantity is too much for your system, 1 1/2 Cups of carbon is recommended. Excess of this can cause tissue loss, although from your description, it sounds more like coral bleaching. If this started at the tips, then photo burn is possible, along with zeo-excess. Mark, your zeo-dosing should not be excessive, so I doubt it's that, but holding all zeo's for 1 wk may help clarify. Bob

[golfish]

Bob,
It has nothing at all to do with the lighting, if anything I over do it on acclimating. It also has nothing to do with Carbon and or Zeovit because these are OLD OLD problems that showed up way before Zeo. Just to try something new I did hold all Zeo dosing a week, nothing happened.

[Aged Salt]

Hi Mark, I'll Alexander to look at your problem. Bluereefs[Mirabel] is an expert & he's perplexed as well. Very interesting, indeed Bob

[Ger]

Mark, did you do construction in your house that created a lot of airborne particles before your problem started? Anybody use any aerosols (e.g. hairspray, etc.) near the tank? Are you using gloves while working in the tank? Are you using any containers within your system that are not food grade? Have you ever tried to check your pumps for burn/melt smell? Just some brainstorming....
