Fay Posted January 10, 2005 Report Share Posted January 10, 2005 O.K. now I'm confused again I started calcium to help Skuzza. So started again to unconfuse me please help: What should all my levels be for a tank stocking Anemones, Leathers,Bubble corals, Brain corals.

reef Posted January 10, 2005 Report Share Posted January 10, 2005 Calcium of 400-420ppm is fine and a kh of about 8-9kh the lower the salinity the lower the levels , say NSW was 1.025, then calcium of 420ppm would be ideal, however if salinity is say 1.023, then 380ppm would be ok.

wasp Posted January 10, 2005 Report Share Posted January 10, 2005 Hi Fay, Many people have an alkalinity higher than NSW in order to increase ease of calcification, and hold PH up. However if using zeovit, it is important to go with the zeovit recommended levels. These are calcium between 420 and 440, and alkalinity between 6.5 and 7.5. If Keeping alkalinity at precise levels is difficult, is better to err on the side of higher. Here is the zeovit manual, which will run you through it all http://www.captiveoceans.com/ZEOvit%20Guide1.pdf Quote Link to comment Share on other sites More sharing options...
Fay Posted January 10, 2005 Author Report Share Posted January 10, 2005 Oops: been running a bit high, that will be why Brendan said to stop running Kalkwasser for a week and see what happens. Thanks for the help. Quote Link to comment Share on other sites More sharing options...
Pies Posted January 10, 2005 Report Share Posted January 10, 2005 A common problem with Zeovit is RTN when the alk gets to high. Most people run their alk higher (reccomended by eric bourneman) to help buffer PH and hold calcium high. Pie Quote Link to comment Share on other sites More sharing options...
cracker Posted January 11, 2005 Report Share Posted January 11, 2005 Another way to dose calcium a bit easier than Kalkwasser is to use Reef Success Calk. No need to settle, just chuck it in the sump, and it also adjusts KH for you as well. Very convenient stuff. Quote Link to comment Share on other sites More sharing options...
lduncan Posted January 11, 2005 Report Share Posted January 11, 2005 Kalkwasser has other advantages as well. It precipitates out phosphate (mechanism unkown). It also boosts your skimmers ability to skim, (again I don't know how). These are commonly known, although unproved, other than anecdotally, I have never had a phosphate reading ever, even doing triple sensitivity. Also skimmer skims more stuff when the kalk drip is running. Layton Quote Link to comment Share on other sites More sharing options...
cracker Posted January 11, 2005 Report Share Posted January 11, 2005 You know a lot of info. Impressive! I hadn't heard that one. Interesting. Quote Link to comment Share on other sites More sharing options...
cracker Posted January 11, 2005 Report Share Posted January 11, 2005 Whats the actual ingredients, does anyone know? Quote Link to comment Share on other sites More sharing options...
lduncan Posted January 11, 2005 Report Share Posted January 11, 2005 Of what? Kalkwasser is just Calcium Hydroxide. Reef Success Calk. I don't know, but is probable calcium chloride mixed with maybe something like sodium carbonate. Which i wouldn't think would be such a great idea if it is, because you'll get calcium carbonate precipitating out pretty much immediately? But I don't know for sure (about what's in it).

reef Posted January 11, 2005 Report Share Posted January 11, 2005 calcium hydroxide Ca(OH) 2 , colorless crystal or white powder. It is prepared by reacting calcium oxide (lime) with water, a process called slaking, and is also known as hydrated lime or slaked lime. When heated above 580°C it dehydrates, forming the oxide. Like the oxide, it has many uses, e.g., in liming soil, in sugar refining, and in preparing other compounds. It is a strong base and is widely used as an inexpensive alkali, often as a suspension in water (milk of lime); it is used in leather tanning to remove hair from hides. It is used in whitewash , mortar , and plaster. It is only slightly soluble in water, about 0.2 grams per 100 cubic centimeters, so its solutions are weakly basic. Limewater is a clear, saturated water solution of calcium hydroxide. It is used in medicine to treat acid burns and as an antacid. Because calcium hydroxide readily reacts with carbon dioxide, CO 2 , to form calcium carbonate, a mixture of gases can be tested for the presence of CO 2 by shaking it with limewater in a clear container; if CO 2 is present, a cloudy calcium carbonate precipitate will form.
