How To Use the King of All Saltwater Additives Safely and Effectively

Of all the supplements available for your saltwater tank, the one that is king amongst all them is kalkwasser. a.k.a. "kalk".

Kalk is highly effective in keeping your tank's parameters as stable as possible and it is very cost effective. It is also part of the hidden secrets on how to keep a thriving reef tank.

Be careful though - using kalk incorrectly can ruin your saltwater tank. Lucky for you, in this episode of Mr. Saltwater Tank TV, I take you through what kalk is and how to use it safely in your tank.

[ReefNewbie123]

is it just ro/di water? or can premixed ro/di water from my lfs be used?

[mrsaltwatertank]

@ReefNewbie123 meaning you mix it in freshwater (RODI water)

Can you make a video on the maintenance you used to do on your 90 gallon?

@MrBettacare You have a freshwater tank now? Trying turning down or removing the bubbles.

@abaneyone I'm using kalk and vinegar and have been very happy with the results.

Hey Mark! Great Episode, I use a Kalk +2 with good results, with about 4 tsp in my 5 gal. top off container! When you mention pH swings of .02, are you referring to the immediate pH change within the tank after the ATO introduces the water to the tank? I know that my pH has consistent changes throughout the day based on time, such as a low of 8.18 to 8.33. Again, thanks for the video, I'm a big fan!

Over years i've had the misfortune of the PH swing when adding kalk. How do you address if the PH rises above the alotted .02 ? I currently use B-Ionic as I haven't had any issues such as Kalk but I havnt gotten the calcium where I want it.

[heyitsevanm]

what kind of ato pump are you using ???



[MrBettacare]

i got a question i have really high ph and it is about 8.8 it always stays at that then can i not keep corals and how can i lower it and can i have fish in there this will be my first saltwater tank

[BDucati1098]

How long can you keep a mixed container of kalk and ro? I have a 33 gallon top off container and only 1.5 gallons of evaporation a day. that means I top off that container with kalk and ro water maybe 1 time a month or less.  Is this ok?
