Anybody Using Trace Element Supplements?

[Beverly]

Now that I have the big three chemistry components, alk/Ca/Mg, under control in our three reefs, by regular testing and supplementation, I'm wondering if I need to be supplementing trace elements as well.

We do 15% water changes each week, along with a host of other tank maintenance. Have BBs in all tanks. No sumps, refugs or skimmers, but have non-invasive macroalgae to utilize nutrients as well as low bioloads in each tank.

I've been the kind of person to not add stuff to my tank that I cannot test for it, so that I do not overdose. But I'm beginning to think trace element supplementation may be a useful thing to do.

If you are supplementing trace elements with a commercial product, which products have you used and which of them do you prefer? Any other comments about trace element supplementation are welcome
