Could not be any happier! By Tom39 on 10/15/13Tom39 would recommend this product to a friendGreat stuff! Only took 5 min to measure and mix it with my ATO water. The hardest part is not letting my wife find out I stole her measuring spoons. Would never go back to daily dosing.
Thank You BRS!!

Inexpensive, easy, quality calcium supplement By Reefrobster on 5/10/13Reefrobster would recommend this product to a friendI have been using the BRS Kalkwasser supplement for more than a year now. What can I say? It's easy to use, inexpensive, and appears to be of high quality. I supplement it as part of my ATO replenishment process. So far it has met my tank's need and helps me maintain my calcium levels relatively easily.
Kalk is the stuff By Joel on 5/3/13Joel would recommend this product to a friendBRS sells Kalk way cheaper than other branded stuff. I love kalk, so straight forward and simple, yet undeniably effective and beneficial in several ways.
Great for ATO water By Alexandria on 4/19/13Alexandria would recommend this product to a friendThis is a great purchase! I have a pretty small tank so the 1/2 gallon bucket that I'm using in my ATO water is probably going to last a life time. Great for keeping water parameters good and great for the wallet with the price! Thanks BRS!
Note: Watch the videos from BRS or Mr.Saltwatertank to know how much you should dose your tank!

I don't have a,auto top off, how would I dose then?
Bulk Reef Supply Hi Rick,
If you don't have an auto top off (which I would highly recommend) then your going to need a kalk dripper of some sort. Check out this video we made on making your own kalk dripper.

I've added kalkwasser to my ATO with the ratio of 1 teaspoon per gallon of ATO volume. It doesn't seem to dissolve, just settle out after a couple hours. I don't run a circulation pump in my ATO as it's only 7 gallons and I'm filling it every week. Would a circulation pump help dissolve the kalk? Would you recommend the circulation pump only coming on with the top off pump? I've read you shouldn't circulate kalk when it's in an ATO, is this true?
Bulk Reef Supply Hey Adam,
You specifically do not want to circulate kalk as you will actually deplete it by doing so (your continuously adding co2 which will deplete it). Its normal to have some sediment when you mix kalk and nothing to worry about. Give it a good mix when you put it in and then just allow it to settle and use it.

how do i know how much to put in my ATO reservior? is there a calculator like the ones for calcium and alkalinity on BRS?
Bulk Reef Supply Kalk can't be added to raise your calcium and alkalinity like you would with two part because the pH swing would be so significant (hence no calculator option). When it comes to kalk you can add up to 2 teaspoons per gallon of top off water but I would start with 1/2 teaspoon. If that isn't enough to keep up with your consumption then you can go ahead and kick it up a notch until you find that sweet spot.
Kalkwasser - This will be used for daily dosing to maintain calcium and alkalinity levels as well as elevate the tanks pH. Because this product does elevate the pH, it is important to dose slowly in small amounts. This product is designed to be used daily to continually replace calcium and alkalinity as it is consumed and not to make large adjustments.
Calcium Chloride - This is used to make larger adjustments to calcium levels. This product has no effect on the tank's pH so it is possible to make larger changes to calcium levels in single doses.
Sodium Bicarbonate - This is used to make larger adjustments to the tank's alkalinity levels. Sodium bicarbonate does have a small temporary lowering effect on the tank's pH. It is possible to make relatively large adjustments to the tank's alkalinity without a major impact on the tank's pH but it is wise to monitor the tank's pH while dosing.
Magnesium Mix - Dosed occasionally to maintain magnesium levels. Maintaining correct magnesium levels helps prevent calcium and alkalinity from precipitating and makes maintaining correct parameters much easier.
