Comments

There is a direct correlation between reduced salinity and increased elemental toxicity to marine organisms. This is why hypo salinity combined with Copper dosing is an affective treatment for Cryptocaryon irritans.

 

BP,

 

The results of your test are the exact reason why we recommend everyone run our full analysis once a year. If you had run this test in time I strongly believe you would have been able to avoid your recent system crash. Fortunately, you have performed this test and can now go forward knowing what has to be done in order to correct your husbandry and maintain a successful system.

 

If you look closely at your aquarium water analysis you will see all of the following are elevated:

 

  • Barium
  • Cadmium
  • Cobalt
  • Copper
  • Manganese
  • Molybdenum
  • Nickel
  • Lead
  • Lithium
  • Sulfur
  • Sulphate
  • Zinc

 

When you are pushing the limits of the elemental constituency of your water, compared to natural levels, you must in the least maintain stable pH, Alkalinity and Salinity.

 

We often hear of a system crash corresponding with someone’s recent vacation. Often, the aquarist is uncertain as to what happened, left to speculate on many creative contributing factors, like a sealed house affecting the pH or things to that nature. Granted, there are many possible factors at play here, however, once your ongoing husbandry is abandoned and your pH, Alkalinity and Salinity levels enter ranges not typically seen, your specimens will feel and suffer the affects of increased elemental toxicity. It only takes one sensitive specimen to succumb and start a chain reaction.

 

Most will look at your results and focus on the Copper; however, it is more the totality of the elevated levels that likely caused the crash. Your Cadmium levels were 5.26 times higher than natural seawater. Cadmium is known to cause Corals to slough off tissue at .5ppm, granted much higher than your levels but the study that determined this was also performed at natural salinity, where yours was found to be low.

It is likely that poor source water, ineffective RO/DI filtration, compromised or non-existent carbon filtration and low salinity caused this system crash. Although there is potentially a plethora of other factors that contributed to this system crash the aforementioned is our official position based on the information we have.

Additionally, you may want to consider replacing your sand bed. Once your sand bed is removed I would point all your powerheads at your live rock and treat your system with CupriSorb, activated carbon and lots of water changes. When you perform the water changes siphon out all the debris that will accumulate on the substrate as a result of the constant high flow from your powerheads directed at your live rock.

The literature on CupriSorb says that with continued use it will remove the copper from your sand bed. I wouldn't follow this in your case as I feel a more agressive aproach is needed.

Best of luck with your changes, and don’t hesitate to contact us with any questions you may have.
