 Topic: issue solved

I decided to get rid of my 10 gal sump and built my own 30 gal. Well Sunday I switched it out and of course had to add 20 or so more gallons of water. By Sunday night my fish were gasping for breath and my corals were all literally melting. I moved everything over to my brothers tank 2 fish died and all my corals are gone except some softies. Oh by the way I left all my crabs and snails in there and they all seem to be doing just fine.
So heres the deal... PH-8.4 KH-15 Ammonia-Less than .25 but more than 0 Nitrate-0 Nitrite-0 Salinity- .023 Temp- 80 degrees Calcium-23
All parameters are in check except slightly high alkalinit

How long did you let the sump you built sit before you filled it up?
Maybe the silicone sealant wasn't fully cured yet?

That is a possibility, I let it cure for about 24 hours. I didn't realize it could be that detrimental to a reefs health. Do you know if that can be fixed with time, or if it all needs to be redone?

I was just getting ready to ask this...my guess is the non-aquarium safe type...the one with a mildew-preventer or something.

Your supposed to use ge silicone 1 not 2....the anti-mold and mildew stuff is what can harm your livestock. I think this was more of a 1-2 punch from not letting the silicone setup long enough and the anti mold, plus the turning over of the sand in the sump. Alot of bad stuff can become from turning over sand.

I would guess a combination of things,
-the sealant if it says anything about mold it shouldn't be used
-moving the sand bed if you didn't rinse it while moving it
-it could have also been the glass not being cleaned enough, I had a tank built and rinsed it but when I moved all my stuff everything melted and died or bleached
Sucks sorry to hear...

How long after you added the salt mix to the 30 gallon sump water did it sit mixing and getting to the appropriate temp before you connected it to the display water? The only reason I ask is because 30 gallons of freshly mixed salt water that hasn't been mixed very well with a powerhead can sometimes be toxic and kill fish and coral...Just throwing out another option.

I mixed it with a powerhead in buckets before adding for aprox 10-15 min each and then let it circulate in my sump for about a half hour until the temperature in the two matched up, then hooked it to the top. Is that enough time?

That should be, I let my new water oxygenate with power heads and a heater for 24 hours or so before putting it my sump. How big is your display again?

Yeah, you doubled the water volume with fresh salt water. IMO, that's what happened. 15 dkh is high, shouldn't be more than 12. The reason I think this is what happened is because I did this before.

I think that sounds like a very likely cause. I guess i will give it a few days and try putting a little fish in and watch closely.

I once over dosed and changed almost 100% of all my water in my system in about a 3 hour period ! I had to use tap water as I had no R/o at the time. 10min mix when I added salt . I had a 72g mixed reef and like 8 fish . Made alot of corals mad but no loses. My best guess would be the silicone . Most use an RTV 100 or 103 when building tanks. (and atleast a 24 hr cure min) Second would be the sand . If you remove old sand it is best to prime with a cup or 2 of the old and rinse the rest until clean . It prevent all the old detriment etc from polluting your new set up. Last would be the cleaning and did you use vinegar to clean ? Sorry for your loss hope this helps in the future.

Some salts claim they are ready as soon as dissolved. However most need more time to have o2 and ph to match the tank. 24 hours is usually the recommended time. I think it was the combo of all those things that started the chain reaction. Anti mold silicone is definitely not reef safe. Your bros tank and your previous sump prob didn't cause the same problems because it was cured more and released less toxins. I bet there is still bad stuff leaching in his though. Anytime a sand bed is moved it can start a tank crash also if not rinsed properly. Especially in older tanks. So just a string of bad things. IMO I would do 100% water change. Reseal the sump using reef safe stuff, rinse the sand in the sump really good and recycle the tank before adding live stock back. It is to bad man I feel for ya. If you need anything let me know.
