Good Day:

I have a mixed reef aquarium with mainly LPS and soft corals. I aim for a 20% water change every 10 -14 days. I have never added any additives but was wondering if anyone would recommend an additive that would help the corals and invertebrates in the tank. I am trying to keep the upkeep fairly simple.

I have been looking at something like:

Brightwell Aquatics KoralColor Aquarium Additive;
Brightwell Aquatics Koralle-VM Trace Element Supplement - 500ml;
SeaChem Reef Plus Additive - 500 mL;
SeaChem Reef Trace Additive - 500 mL;
Kent Marine Essential Elements Additive - 16 oz;

Thanks,
