Best calcium supplement?

[Sparg93]

I was wondering what was the best, most cost effectve calcium additive out there?

I have a small 46g tank and low Calcium levels, what do you recommend??

I am currently using ESV B-Ionic Calcium... (heard it was pretty good)

B-Ionic has worked well for me, but there's a recipe for a DIY 2-part online:

That should cut costs.

A lot of people, including me, use limewater as well:

I use an auto-topoff setup, which includes a peristaltic pump and float switches. The startup cost is high, but lime is very inexpensive.

This article talks about a few more methods as well:
