first dKh and Ca tests

[Fishward]

hey,
i just picked up a dKh and Ca test kit and got 120(dkh) and 400(Ca)
Are those good numbers?

Ca is is good, think you might want to recheck the alk (ppm maybe).

See here (http://www.reefkeeping.com/issues/2004-05/rhf/index.php) for targets

120 ppm is on the low side for Alkalinity in the link I gave

You want your DKH in the 140 - 200 ppm range
