jennyf78 Posted September 29, 2008 Share Posted September 29, 2008 is this posible, 2 different test have concluded his calcium is very high, both where salifert test. one old thought that might have been the problem so got a new one but got the same reading 650. he dosnt dose extra calcium in the tank. water changes once a month has a small amount of corals. his dkh is normal dont remember the number off hand. he has a 55 with compact lighting. any suggestions why this might be?

Nyles Posted September 29, 2008 Share Posted September 29, 2008 I would probably do 10 gal water changes weekly for a month to fix, or you can move salinity faster if he has less sensitive creatures. Cant point any fingers on the where it came from without more info, is this a new tank? Make sure you test new water going in to, would use a basic salt not a reef salt as it is lower in calcium Quote Link to comment Share on other sites More sharing options...
andy Posted September 29, 2008 Share Posted September 29, 2008 I'm suspicious of either test kit or human error. Calcium at 650ppm is really high; it's hard to imagine getting to that number in a tank that isn't dosed calcium in some manner, particularly given the alkalinity levels are normal. Is SG correct? Has he taken a water sample to his LFS and had them check it? Quote Link to comment Share on other sites More sharing options...
dsoz Posted September 29, 2008 Share Posted September 29, 2008 +1 get it checked at a LFS. They will usually do most tests for free. dsoz Quote Link to comment Share on other sites More sharing options...
Lowman Posted October 17, 2008 Share Posted October 17, 2008 I had calcium up to 900 one time, just before I quit using Oceanic salt. It takes time and patience to lower levels that are too high. Slow and steady wins the race Quote Link to comment Share on other sites More sharing options...
pledosophy Posted October 17, 2008 Share Posted October 17, 2008 My test kits don't even g that high. What kits are you using? Quote Link to comment Share on other sites More sharing options...
Lowman Posted October 21, 2008 Share Posted October 21, 2008 I have a friend who is a chemist and he used a kit at his lab. Quote Link to comment Share on other sites More sharing options...
