Sorry I dont have the link, I was just doing some research and stumbled onto to it via google. There is some info on RC.MINIATUS said:Don
You got a link to this. I drip Kalk but not in a Slurry.
Mike,mojoreef said:I still dont get it Don. its not like its going to be more concentrated. Did they give any reason for doing it??
And so, it is my advice to aquarists who responsibly test for the additives they use, to dose calcium hydroxide in increments (whisked briefly in a cup of cold purified water) that do not raise the pH of a system by more than two tenths of a point. The portion will begin conservatively small (starting with 1/16th of a teaspoon per one hunderd gallons of system water) and increase until the pH climbs two tenths of a point or the tested amount satisfies the daily demand for calcium in that portion, whichever comes first. A digital pH monitor makes very short work of this process and is highly recommended with this style of dosing calcium. Most systems less than 3 years old and under 200 gallons in capacity can have their daily demand for calcium satisfied in a single shot of slurried kalkwasser after the sun goes down: a one minute procedure after the parameters have been set. To maximaize phosphate fallout and calcium uptake, it has been observed that kalkwasser additions are more effective if they can be safely dosed into the main display rather than the sump. This method of calcium supplementation should appeal to aquarists and coral farmers who cannot afford or choose not to invest in calcium reactors. I do not even believe that calcium rectors are necessarily better, although they are excellent vehicles for calcium and alkalinity maintenance. The contrast between the methods is simple. Calcium reactors are convenient but expensive. Manual applications of kalkwasser could be very inexpensive, but requires daily attention. Coral farmers starting up or operating large facilities are advised to dose kalkwasser manually until they are so wealthy (wink) that they can afford such delightfully convenient toys for each system. Until then, dosing really isn't so bad. The nature of coral propagaion is inherently labor intensive and requires consistent, daily attention. The one-minute diversion of dosing kalkwasser is simply part of a farmer's day. Private aquarists are otherwise encouraged to seriously consider automated calcium supplementation, as cost management is not quite so critical in not-for-profit operations.
