The link between alk & nutrients

Hello,

As per the header.

What link does Alk have with nutrients in the system. Ive seen a few members remark that high Alk doesn't farewell with a low nutrient tank?

Thanks

In a system with ultra low nutrients, increased Alk levels can cause a burnt appearance to some SPS. This doesn't happen with all species. As always there are exceptions and each system is different. Light PAR intensity comes into play as well as flow.

Your best bet is to see to place all the nutrient levels within acceptable ranges, don't over feed, and shoot for consistency.

That's a good summary. We don't know exactly what might be happening, but sometimes corals do poorly in tanks with high alkalinity and lower nutrient levels. Targeting something like 8 dKH probably is safe enough, but different tanks respond differently.
