Was wondering if anyone does Strontium tests & if they do & it is very low, what they use to bring it up?? Mine didn't even show up on the chart, so it is pretty low. I have a 220 SPS tank & a friend told me to test for this.
Thanks
Thanks

"it's in the water, it's used". The underlying mechanisms are not fully understood though.
Sitting in a waiting room reading.. This was interesting.. (I'll dig up my other posts that touch more on it) We still have a lot to learn, but if we're going to replicate environments, I think paying attention to strontium is a basic necessity.

I don't know of any evidence that strontium is needed or beneficial to most hard corals, and the experience of many reefers who dosed it for years and then stopped is that many saw no apparent change. There are specific organisms that have a clear need for strontium, but few reefers keep them.
That said, one can hardly view it as a problem to maintain NSW levels of strontium, so there's certainly no harm in doing so if you think it is or may be useful.
I discuss it more here:

Aragonite forms without strontium.
That pdf doesn't talk of strontium.
And you're saying aragonite forms in corals, without strontium? And you're talking before or after biochemistry manipulation from the host coral?
I guess it could be a more simple question, has there ever been a coral analyzed, that contained aragonite, that did not contain strontium?
Links please.
So, given strontium makes it into the coral skeleton, we've never seen aragonite in a coral NOT contain strontium.
But aside from that, you have no factual basis for saying "the coral mistakenly uses strontium"?
Again we're looking for facts and evidence right?

This is a clear result of it looking chemically like calcium. It is not due to any biological need or control. There is no biology needed for its incorporation..
