Seachem Reef Kalkwasser

Seachem Kalkwasser is used to prepare limewater solutions that maintain calcium concentrations at natural seawater levels and increase pH without impacting carbonate alkalinity.

  • Very pure calcium hydroxide
  • Ideal for increasing calcium in top-off water
  • Increases pH with no impact on carbonate alkalinity

Seachem Reef Kalkwasser is a pure calcium hydroxide with unsurpassed purity and solubility characteristics. Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that will maintain calcium concentrations at natural seawater levels. Kalkwasser solutions maintain calcium directly and carbonate alkalinity indirectly. However, its capacity to perform these functions is dependent on evaporation rate and CO2 concentration. If these two factors are insufficient you can provide additional calcium with Reef Advantage Calcium™, Reef Complete®, or Reef Calcium™, and carbonate alkalinity with Reef Builder™ or Reef Carbonate™ (do not mix these directly with a kalkwasser solution).

Many who use kalkwasser are quite successful with their marine systems and find it to be an effective way of maintaining calcium. However, it can be a difficult technique for the beginner to master. The carbonate alkalinity must be monitored and adjusted to ensure that it does not become depleted through chalk (calcium carbonate) precipitation. The magnesium concentration must also be monitored and maintained since precipitation of magnesium hydroxide (arising from excess hydroxyl ions) can lead to a change in the balance of the various buffer systems present which can result in drastic pH shifts. Additionally, magnesium is an essential component of seawater that is required by all corals. There will be an increase in the build up of chalk on substrate and plumbing surfaces which will require more frequent cleanings in order to maintain the proper functioning of the aquarium. If due care and diligence is paid to all of these factors, there is no reason one cannot maintain a successful reef system while using kalkwasser. While Reef Kalkwasser™ is a high purity and economical limewater mix, the beginner, or someone with not as much time to devote to their system, may prefer to use other less involved methods for maintaining proper ionic concentration levels.

Directions

Never add this product directly to the tank. Add 3 g (1 teaspoon) to 4 L (1 gallon*) of water and mix to dissolve. If using pure water, a fully saturated solution is prepared by adding 6 g (2 teaspoons) to 4 L (1 gallon*). Drip this solution into tank. Monitor pH and carbonate alkalinity. Adjust rate of addition to maintain a stable pH (8.3–8.4). HINTS: Adding 4 L (1 gallon*) of a saturated kalkwasser solution to 150 L (40 gallons*) will raise calcium by 24 mg/L. Always use the clear supernatant (top solution) only and do not allow undissolved material to enter the aquarium. Keep this container tightly closed when not in use and minimize solution/air contact to avoid calcium carbonate formation/precipitation.

Avoid contact or breathing dust. Do not eat or get in eyes. In case of contact, flush area with water for 5–10 minutes. In case of eye contact, wash eyes with water immediately (5–10 minutes) and seek medical attention.

Works Perfect!
Size: 24"X24"
Same scenario here as a lot of other reviewers... We've got a 10-week-old pup that used potty pads at first... But now is in the teething and let's tear everything up stage. It was starting to get dangerous even with other holders she was tearing up the pads completely and we were worried she was going to ingest them. We looked at several different products, including the over twice the cost metal wolf brand. But I have to say, really glad we went with this one. It does take a minute to snap together properly, but once you do changing out pads is a breeze. Once our girl (Mini Poodle) went on top of the greats and used the bathroom we gave her a big reward with lots of praise and a treat. She hasn't been able to tear it up at all. And I believe since she can smell her marking, she has been going back and using it about 7/10 times. More recently, the success rate has been going up. Like I said, she hasn't been able to flip it over, break it apart etc. So we are incredibly happy with this purchase and has made our lives so much easier. Once she gets bigger we will see how she handled it. And if she is able to break it apart. But I doubt it, there is a fairly satisfying click when you lock in both sides with the pad beneath. We are using Frisco pads from Chewy large size and they fit pretty much perfectly. You have to fold the blue border slightly but it works great!

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.

Great for smaller dogs
Size: Small
These two balls are perfect for the smaller mouthed dog that loves to play fetch. These balls are not only super durable (lots of teeth biting), but float in the baby pool we use for our miniature dachshunds. The value here is much better than you’d find anywhere else. The noise, if bitten hard enough, was “low” at best. Easy to spot/find if overthrown. Will definitely buy again once these are in bad repair; so far, so good-love these for my fur babies!

My dogs favorite balls
Size: Medium
These are great for my dog who always has to have a ball in her mouth. Not too hard so I don't have to worry about her teeth. They last for ever. They do lose their shape a little over time (like I said, she always has a ball in her mouth) they become a little oval in shape. They still bounce, she still chases it and she still chews on it so I don't think she notices or cares. I've gotten her a bag full of these over time and I have only seen one that she chewed a chunk out.

My Dachshunds Love These
Size: Small
These balls are durable, flexible material, highly chewable without being easily destroyed. I stuff them with Milkbone Maro Snacks, which are just the right size to twist into the holes in the ball. My dogs literally get an hour+ chewing and chasing entertainment from these. They chew them, they sometimes 'pop' out of their mouths, go rolling across the floor, dogs chasing them. This satisfies their urge to hunt prey. Dachshunds can easily tear this kind of stuff-it-toy apart. These have lasted for a long time without tearing or shredding. I would NOT recommend them for a dog much larger than a tweenie weenie. They're a bit on the small side and might be swallowed by a larger dog. It would be cool it they also came in a larger size (and probably ball wall thickness also) for the bigger dogs to enjoy. These stuff-it chew balls are better than the kong balls my dogs had before these. Highly recommend them.
