its a secret mix of 11 herbs and spices :razz:

I have no idea, I would imagine its some sort of chemical mix that reduces chlorine and chloramine to something inert as well as ammonia and nitrate. Their website says its a "proprietary aqueous solution of complexed hydrosulfite salts". Which basically means they're not gonan tell us. However something in it is a coral killer in high doses.

It's super concentrated. I don't think people realize that a capful is good for 50 gallons, whereas Hagen's version (Aquaplus I think it's called) is a capful for every 10 gallons.

here are some pics of the tank if anyone can tell me whats wrong. did the 20 % water change. its a bit cloudy now after the water change. is that normal..

u can see how some of the corals are shriveled and not at their best.

please help. whats wtrong

what should i do.

Whats wrong is that your corals are dying/sloughing tisse, and your tank is probably trying to cycle again because of the increased ammonia? Have you checked all your parameters??

there is no ammonia in the tank. i have the ammonia alert card and i check everything over and over. all good

are the corals dead? or they gonna come back??

only time will tell. I'd do another 20% water change on Saturday. run some carbon in a filterbag. then the waiting game begins. I don't know what that pic of the coral on the sandbed is but the leather might recover, they can sometimes be cranky bu then perk up.:biggrin:

so is it becuase i never did a water change since september when i set the tank up that is causing this?

Yes. You got bad advice about not doing water changes.

so this change should bring things back

It will help the corals.

What happens is the tanks chemistry changes over time and elements important to corals get exausted. A water change helps replenish these elements and removes waste from the tank.
