Increased Sn, V and Ba concentrations...

[cb684]

My corals are doing well with good color and good growth on my 400 gallon system. With that said, about 1.5 months ago I got this result from a ICP-OES Triton test, and I was wondering how much i would achieve using ROX activated carbon, and/or polyfilter or Cuprisorb in lowering the elements in the list below.

What I am trying to correct:

I am not very concerned at this point. But I am willing to try something, other than large water changes, to correct those values. My water change is a continuous 1%/day and I am very happy with the tank stability, and that is why I am trying to stay away of doing the multiple 15% water changes that Triton suggested. Any thoughts?

Thank you,
CB

Whats the possibility its coming in with your salt? Water changes wont reduce them if its in the salt. Not positive this is the culprit, just a possibility?

I would think it is unlikely. I have been using Red Sea blue bucket since the beginning of this tank. I thought Sn could be from stabilizers in the pvc I use (maybe I am completely wrong). But this system has far more than the average tank, roughly 30 - 50' with water passing through them all the time. Ba is frequently high on tanks that run Zeovit. I was using their zeolites until last December, so I think that may be the source. Now, I have no clue where V is coming from.

I don't believe any of those methods will impact barium, which chemically is quite like calcium. Tin can take a number of forms in seawater, but might be helped by the polyfilter and to a smaller extent by GAC (if the tin is bound to organics).

Vanadium is consumed biologically and I probably wouldn't focus too much on reducing it. It is a component of some trace element additives, if you use any.
