coral for soft water

[Susan.C.Jorgensen@Dartmouth.EDU (Susan C. Jorgensen)]

I keep a small chunk of coral (about 2" long) in the basket of my =
AquaClear filter and it helps.  The pH is more stable in that tank =
than in my other tank of same size (10g).

I have soft water too, and thought that it was attributable to =
being from a deep well that I *think* draws its water from close to =
its source since I live up high (relatively). Am I way off base?  =

Add a decorative seashell to your tank.  It will slowly dissolve =
(over
decades), raising GH, KH, pH and a whole bunch of other Hs.   ;^)>

If that is too weak a medicine for you, try a LITTLE crushed coral =
gravel
in a net sack (so you can remove it if necessary).

Good luck.   =20
