SPS pros- What are you dosing and how?

[ReefingRelapse]

Title says it all. There's so much information on the internet it's a little overwhelming, started to feel like I need a million reactors and dosing pumps and solutions for a simple biocube. I'm curious to find out what yall are dosing and how (manually or automatic) 

Any additional information is definitely appreciated... along with tank pics

You should only dose what your tank consumes.

 

That requires testing for a week.

 

Test new waterchange water

Test after waterchange

Test every day for a week

 

That determines what you start at and what the tank consumes

As stated, you only need to dose what's consumed, the main 3 are going to alk, ca and mag. Most tanks with frags will be fine with weekly or biweekly water changes. So in other words if your calcium and alk are dropping too much in between water changes you're going to want to dose to keep levels as stable as possible.
