Last Saturday I sent out a Fauna Marin ICP to try out their testing, which appears to provide additional content and insight. So it took 6 days including shipping to Louisina to receive the results, which is pretty good.
This was meant to be a baseline test, and the next step would be to share the results with Captiv8 to adjust the trace element dosing according to these results.
Several parameters were out of balance but overall not a bad result. However, the one item that confused me was the difference between PSU and PPT when it comes to salinity. Apparently my salinity was too low as my PSU was 33.8.
My Milwaukee can measure PPT, PSU, and SG. I typically use PPT after several reading in my earlier reefing days (not too long ago
) that this would be a reliable measurement to go by. Several rounds of Triton ICP testing confirmed that my salinity was at around the 35 PPT I am targeting, confirming that how I use the Milwaukee and the Milwaukee itself being reasonably accurate.
Fauna Marin states that PPT and PSU are equal, i.e., 1 PSU = 1 PPT. However, when I measure PSU with the Milwaukee, this is typically one unit below the PPT amount. So their ICP results appear accurate and suggest that I should increase salinity, but I am concerned that this would overall be too high - any thoughts on what I should do?
Other parameters out of balance were the following:
- Idodine is rather high: apparently a common issue when using Captiv8 IsolMT. I might need to reduce the dose for now and dose their individual traces.
- Zinc too low
- Copper too low
- Manganese (far) too high: This is interesting, but the gonies currently LOVE this.
- Iron too high: This is something I had previously too, I feel this is a Tropic Marin Pro Salt issue, and probably not a big issue.
- No Chromium detected - need to be dosed
- No Cobalt detected - need to be dosed
- Aluminium too high - I might need to act on this rather soon.
