Kent coral builder

[Proteus]

Ok

So I tested added let mix in DT for 6 hours then test again

I started at

6.5 dkh =. 2.32 meq/l

Added 1 tsp of coral builder

Ended up with

8 dkh = 2.85 meq/l.

1 tsp raised 42g 1.5dkh = .53 meq/l tested with Elos

Seachem reef builder calc says 1.2 tsp at 42g to reach that alk so fairly spot on for me
