What is kalkwasser for reef tank?

-Kalkwasser raises calcium and alkalinity. Calcium and alkalinity are what corals, snails, and clams use to build their bodies. In a reef aquarium the calcium and alkalinity levels drop as the animals inside the tank grow.

How do you drip kalkwasser?

How long does kalkwasser last?

Visit Sk8r’s homepage! The limewater should last a long time, easily a month. Premixing that way is fine. I mix a 5g container at a time, and drip from it for a few weeks.

How does a kalkwasser reactor work?

The way a Kalkwasser Reactor works is quite simple as they essentially are just a mixing chamber for RODI water and Calcium Hydroxide. The clear solution that resides on top is then dripped into your aquarium based on your tanks demand for calcium and alkalinity. If you need more calcium, increase the drip rate!

How is kalkwasser calculated?

Kalkwasser With an ATO Add up to 1 1/2 teaspoons per 1 gallon of fresh top off water. Start by adjusting your Calcium, Alkalinty, and Magnesium levels to where you want to keep them long term.

How long does kalkwasser last after a water change?

I have a 30 gallon tank and my alk is always 6.7 after a water change and goes down to about 6.3 within a few days. Tank is up for 3 months and have some zoas , Acans and very few sticks like 5 lol. I am going to try dossing kalwasser and see if I can raise my alk.

How often should I take kalkwasser at night?

It sounds like you have an alk draw of only 0.2DKH per day or so so an easy solution would be to use an online calculator to figure out how much fully saturated kalkwasser that takes and drip that over the course of every evening. That’ll help keep your pH up at night and also replenish the days alk/calcium consumption.
