Dosing dilemma

[xanthurum]

Wanted to get opinions on dosing options. I have a 175 gallon tank with a very large sump/refugium and I am in the process of stocking with SPS frags. So far everything is staying stable with water changes but I know I will be needing to dose the big 3 to have long term success so I am ready to get the ball rolling.

The 2 options I've been thinking about are the new Bubble Magus BM-T11 with 3 containers.

The other is using my ATO, I know some people do this by adding the needed supplements to the ATO and in turn they get dosed that way.

My tank is rimless and I live outside Phoenix so I go thru a lot of top off water. Opinions please. By the way I will be starting a build thread soon.

Some use kalk in their top off, but I don't think thats a great long term solution. I would towards a pump.

Kalk in the ATO is a great way to stabilize ALK and Calcium. Especially since you evaporate a lot of water this allows for the addition of even more Kalk. Kalk supplements Akl and calcium in the same ratio they are consumers, and also helps raise PH.

But it also doesn't allow control. Can overdose easily with high or inconsistent evaporation rate. Some top offs dump quite a bit of water in at a time and can spike pH quickly.
