Ok, i need help, here is the history on my tank.
ph- 8.0
nitrates- 0
nitrites- 0
amonia- 0
kh- 7dkh
calcium- 800
salinity- 1.021
30 gallon reef tank
So my question is why is the calcium so high and is the kh to low?
Thanks

test both alk and calk with a different test kit to make sure the reading are right... test kits degrade over time... ( maybe take a sample to a lfs or friends house to test it ??) and if it is off.. i would mix a little bit of new mixed saltwater... airate it ( stick tube into intake of the PH ) for about 10 minute then test the new mix 30 mins later to see what the readings are... if they are in line and your tank is in fact 700 calk and 7 dkh then id do a wc.. probally a 10% then another in a week or soo .. test agin and go from there...
