Seachem Reef Kalkwasser 500gram

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.

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.

Good product for aiptasia

Used as intended the growth of stony corals and calcareous algae is increased. I also use it to kill aiptasia anemones and it does great! Be sure to wear gloves handling it though, it has a very high PH and can make your skin feel raw (first hand experience lol)

I used this for sometime with my reef. It worked fairly well but as I moved to sps I decided 2 part was a better choice. But overall it kept my water parameters with in reason. It did swing from time to time due to the rate of evaporation changing through the various times of day.

I have neen in the Hobby for over 40 years and i must say that kalkwasser Is one of the best product for coral, one is its easy to use, two is coral love it, you can see how your coral will open up when using this product, it's like the best secret in the Hobby.

Buen producto y fácil de usar.

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

Order this 24 hours ago, here already. Last time I bought this product from a different company it came without a foil seal. Nice to see that this company hasn't tampered with it.
