Supplements for Reef Tank

[Oceantony666]

I have a mature reef tank with 4 X 110 Watts VHO and one 40 Watts HO
Which supplement system should I use Sea Chem or Red Sea I just started bought the NO3 PO4 X additive PO4 a bit high trying to lower them.
So what should I use? Mostly LPS now but I will add a few SPS
Thanks a lot

You want to measure and supplement calcium and alkalinity. Which method you use is probably a bigger decision than the exact brand.

I'd suggest a two part system, unless you want to use limewater in an ATO.
