Wow, I'm reading the wrong stuff, I didn't realize limewater, or is it kalkwasser, that would take care of both? I thought the kalk only took care of Alkalinity . Do you have a sps dominated tank? And what size tank are dosing 500 ml? Limewater seems to be the most cost effective way to go, correct?
Its a 200 gallon tank. Only a few sps right now. My dose is really low. Yep it takes care of both, thats the nice thing about limewater. I only lose about .5ish dkh per day of alk. Limewater and kalkwasser are the same thinf with different names. The chemical name is calcium hydroxide. The only downside to it is if you add too much ph will rise, thus very high demand tanks will have problems keeping alk and cal up with limewater because the ph gets too high for the amount needed. Limewater/kalkwasser is calcium hydroxide mixed into fresh water. And yes limewater is the most cost effective way for me. I buy it in bulk. I bought a container of "no name" brand lime for like 30$ cad. In 6 months ive used half or 15$. And i waste lots when i wash it out, and because i dont measure, so it might last even longer if i were to use the 2tsp per gallon. For me its like 30$ a year on low demand not measuring Very high demand for alk/cal might be 100$ a year with lime but thats a guess.
