high lithium

I had my water tested by ATI, had a couple things a little high, a couple things a little low, nothing crazy except for lithium - it was 2229 ug/L. The reference value is 168.4 ug/L. I suspect it might be from the trace of light grease or oil on the Jebao pumps, IDK.

I planned for the no water change method. I'm running cuprisorb, rox 8 carbon and purigen. Algae filter but no skimmer.

I only have live rock and am ready to start adding animals.

Do you guys have any idea how bad this lithium level is? Does it even matter?

Did you use lithium grease on the pumps? I probably would ignore the reading, since I'm not sure that I believe it. If the level is high, it might kill starfish, for example. Other animals probably won't care.

I didn't use any grease on pumps or anything else, although I have used a tiny bit of Vaseline on O rings in the past. I don't think I used any Vaseline on this build though.

ATI recommended three 20% water changes. I hate to do that unless it's absolutely necessary because it's a big system.

It wont be 100% skimmerless....I set up aeration to give pH a bump and it looks like it will end up being an old school counter current skimmer. I wonder if lithium is that high and is still hooked up with grease, (assuming that's where it came from) a bitty skimmer just might take it out.

I don't know whether the lithium (if present) will bind with organics. If it does, carbon or skimming might remove it. I suspect that the test is wrong. I'd just ignore it, personally, but water changes with a low-lithium salt mix would be the only way to fix the problem. If the lithium actually is that high, I suspect that you've got a bad batch of salt. I can't think of another credible source. Lithium grease won't do it.

Thanks. I'll add some snails and see how they do.
