TUNZE OSMOLATOR PUMP With DOSING
- Thread starter dsouza
- Start date
It will shorten the pump life and void the warranty. Lots of people do this anyway as the pumps are only about $18. They usually last 6 months to a year used this way, the best life will be achieved by keeping the pump out of the slurry on the bottom and mixing a dilute solution with 1/2- 1tsp per gallon. The best way will be to add a kalk reactor or our Calcium Dispenser which mixes the solution after the pump, the biggest advantage is that the mixing is occuring in a sealed vesicle and this prevents the reaction with the CO2 in the air that causes precipitation and loss of potency.

I am thinking of buying this for my osmoregulator, and I was wondering if the kalkwasser is able to settle, or does it deliver a slurry...... how many gallons of water can pass through before adding more kalk? How much kalk do you load it with? I have a 100g mixed stoney coral and clam tank
This product is designed with the understanding that Kalkwasser will never be able to meet all the calcium demand of a stoney coral tank. It holds 4 teaspoons of powder and that is sufficient for one fill of our reservoir 5002.25, which holds about 6 gallons when you install the calcium dispenser inside of it. It delivers a saturated solution, not a slurry, the biggest advantage being that the solution is mixed in a sealed vessicle limiting its exposure to CO2. It is really to be used as an adjunct to a calcium reactor, the kalk binds excess CO2 and stabilizes pH, and adds a bit of Calcium but kalk is a weak source of calcium and with realistic dosing regiments is not going to elevate Calcium much no matter how you use it. If you add a lot the pH shoots up and precipitates calcium, their just is no way to escape this.

Thanks for the reply, sounds like it will work well for my system. Can I simply add kalk every 5 gallon, or does the canister need to be rinsed out? If it needs rinsing, does it have quick-disconnect fittings?

It should be cleaned out maybe once every couple months, I just rinse it out and fill it with vinegar, it doesn't have any quick connects but it is pretty easy to get the hoses off and it just clips into the bucket- that is an important thing- it has to install in the bucket as a safety in case a hose popped off andd they will because the kalk hardens the tubing and they don't have the elasticity anymore after a while.
