Kalk

[Irenicus]

I was shopping around online for Kalkwasser.

Any brands better than others? Preferences?

Also, I was thinking of getting Strontium. Same questions as the Kalk.

Any brands better than others? Preferences?

Thanks!

If your going with Aquarium use Kalk, ESV is the most used.

Strontium, just buy small and see if it makes any differences for you. Generally, I only add when trying to cure LR. I like the Seachem powder form because long shelf life. Strontium can be dosed along with the Kalk.

Yeah the strontium is for curing rock.

Thanks Dave.
