Thanks for the info. I think that is all I got but I'll have to check. I might have to use another testing service to verify. The calcium does alarm me but I have not seen any adverse effects so far. How would I remove the lithium? I believe this was coming from my af vitamin dosing, which I have since stopped dosing and stuck with my frozen food regiment.First, where are the rest of your results? That looks like only the first page?
Second, I agree with RHF, the only two items here so far of concern are the calcium and lithium readings. That calcium if correct is really high, going to contribute to excess precipitation in your pump and elsewhere, don't know if it's actually harmful to livestock. As for the lithium, some salts, including IO Reef Crystals in my case, contain high levels of lithium but those are only up to around 600, your level if correct is 10x that at 6110. I don't see how that could be coming from the salt.
Personally, before getting too concerned, I'd confirm these results by sending off a sample to another lab like Triton or ATI (either will take about 2 weeks.)
PolyFilter will definitely not remove lithium.
