Seachem Reef Kalkwasser 250gram

I'm only dosing about 250 ml of kalk per day into my 164 gal majority LPS reef, spread out evenly over 12 doses. But even at that small amount, I've seen great stability in my calcium, alkalinity, and pH.This stuff works well, and it's very cost effective. This jar will literally last me more than 9 months. Worth it to spend a bit more for a pure, high quality product, as opposed to food grade pickling lime.

Very good 👍

Use with auto top off

Good product for aiptasia

good

not easy to get the right dose . much better if used with dosing system . I found out my calcium levels are plenty stable at 4 plus if I do weekly water changes . I use more salt but stopped all additives . todays salt is much better than the old days .

Started dosing this in my tank and immediately could see the difference. Corals seem happier. It mixes up instantly and you get alot in this small container.

Mix this into your auto top off and forget about fluctuating calcium levels! This has been a life saver in my pico reef tank.
