We were using TMPR Salt and had been having a rough time with fish and coral. I sent my first ICP_OES to ATI and received rather good results but some issues with a few items I would like some guidance. In particular, the following top two are clearly too high, while the bottom two are moving in the wrong direction:
Silicon 2116 micrograms/L
Vanadium 134.9 micrograms/L
Zinc 16.54 micrograms/L; and
Nickel 7.68 micrograms/L.
This is a 75G mixed reef tank with sump up about 4 years that is just starting to move out of the ugly phase. I did a Brightwell NO3 block to reduce nitrates and have dosed Phosphate E to lower phosphates with some success. It was started by my nephew until my recent arrival. I do not understand the high Silicon or Vanadium. Some posts related to both being high may be related to black substrate, which he chose Carib Sea Arag-alive when he set up the tank, which is the current substrate. I remain uncertain whether this could be the culprit; however, such a long standing cause may offer a reasonable explanation for the tank never really progressing.
Any suggestions on how to proceed on lowering the Silicon and Vanadium? Just an FYI, the RO/DI sample was unremarkable - null.
