maintenance

50 GPD Aquafx Barracuda(RO/DI)- Filters/Cartridge were changed 3 months ago. Membrane was changed 10 months ago. My RO water is stored in 5 and 1 gal water jugs. All my buckets are rinsed thoroughly and wiped dry with paper towel before and after I mix up my salt.

I change out my RowaPhos,Carbon at the end of every month. I do my main water change of 6 gallons every 7 days. The tank is siphoned out 1-2 times in-between my main water change,and I might add a 1-2gal water change depending on how my corals look. All pumps and equipment are taking apart and cleaned at the beginning of every month.

My water is always crystal clear. When I added the 6 gallons of salt mix from this bucket my tank water turned very cloudy,milky white. My female clown fish which is usually docile started Frantically swimming around the tank. She did this for hours. A few hours after the water change all my Turbo snails stopped moving and closed up in their shells. 8 Hours later 2 of 4 of them were dead. Even the bristle worms were not immune. I had dozens either dead or dying. The only coral that was not affected were my Purple Death palys.

Different species of LPS are not all the same.(Some are more hardy than others) Also different grades of LPS are more sensitive than others. Duncans and Micromussa are more hardy and less sensitive than Acan lords. Ultra Acan lords are much more sensitive than grade A or B. So,the first to die were my ultras,next were the A-B,and the last to go were my micros.

Now about the salt. As I said in my first post. I have been using Reef Crystals off and on for years with no problems. The salt I was using before this bucket was a 200gal box of Reef Crystals which I purchased last Sept

I don't know if its the batch or just this particular bucket,but all I know is that this new 160 gal bucket of Reef Crystals salt is contaminated or just bad. Two things really concern me are that the salt is not packaged into a plastic bag. It's just dumped into the bucket. The other alarms me is that this bucket came with a free T-Shirt inside. From my understanding manufacturers use Formaldehyde when shipping clothing. So could some kind of chemical from the T-Shirt contaminate this salt?

I've done a 80% water change with a new bucket of Red Sea salt. My water cleared up and the fish look more relaxed, Turbos came out of their shells and started moving again.This just confirms theres nothing wrong with my RODI(which I already know)
