The results are in!
This is my tank before I got rid of the emergency-homed 'way too big for my tank fish'.
I do believe I may have used Reef Plus the week before, so it's questionable where the Al and Cu come from. There is Cu in the Reef Plus. (I'm moving onto the Red Sea program though) Unless of course the rocks I got were in a tank that had a copper bomb of some sort.. There is a few rocks that are fairly new. Or of course unless TechM has a bit of Cu, the TechM bryopsis attempt was a few months back. (didn't work)
Otherwise the sand is the Black Tahiti sand iirc? I'm assuming this is the source of the Al, unless it is indeed the salt.(Fluval sea salt)
I think I'm going to send in a fresh sample of just the salt mix. Already got new sand since I suspected the black sand may be playing a role in the non-stellar look of a few corals.. I got some Special Grade Seaflor sand rinsed and ready, but I was awaiting the test results.
*Edit
I bet it is the black sand for the aluminum, perhaps the copper as well? (I don't dose Reef Plus except for maybe once every couple months and that's with weekly 15g wc's on a 75)
I use Poly-filter as well, it's only ever tan/brown, but I run biopellets and the pad is in the skimmer output.
Here's what they say, so it obviously is absorbing Cu and Al. So this is probably my reduced ambient levels leeching from the sand?
Another important and patented feature of the "Poly Filter" is its unique ability to change a different color with the absorption of specific pollutants. It turns blue with a copper salt, light green to aqua with free copper, orange with iron, red with aluminum, yellowish green with ammonia and white to beige to brown to black with the absorption of harmful organics.
Ya, on the Reef Plus bottle, .001 mg per 1 g. So I don't think that's the source.
So either live rocks leeching or black sand.. I did get the rocks from someone who had a tank for 15 years, found black areas on the rock so their tank probably crashed. Pre-crash I guess I have no idea if they ever used copper or not.
Anyone seen any triton results from someone with black sand?
For curiosity as well, I took a 736 Phosphorous test at the same time I took the Triton test.
Here's from my calendar:
triton test sampled, 0.1962304 po4 according to hanna (+.011 then)
So I guess they're *fairly accurate hehe
