Help. Im so confused.

[t11t5]

There are so many addatives I have no idea what I need. Someone help me please. Do I need to add anything?
I use Reef Crystals mix. I do a 30g water change on a 150g every other week.

Many tanks need alkalinity and calcium supplementation on a daily basis. This article might help:

B-Ionic or a similar 2-part is an easy way to get started, in my experience.

Magnesium can be another issue. I'd recommend testing for magnesium every couple of months. If it drops, there are various supplements that can be bought.

You could start there, and worry about the other possibilities (iron and silica come to mind) later.

Test your water... if its low on anything, and after a water change its still low, you need to supplement that thing.

That means physically testing for many different things, alkalinity, pH, salinity, calcium, magnesium, strontium, iodine, phosphates and the like.

Get as in depth as you like, but dont supplement without a test kit for that supplement.
