Keep up KH and CA

[csaba911]

Yes calculator say that, I should mention even with 200ml wont get up to 480 where was no problem before, usually I'm happy with 420-450 and 8-9 DKH.
Will try to get MG up to 1400, my salt mix "Reef Chrystal" also have strange low KH to start with 7-8 and 400 CA, I had used various salt mix in the past all worked fine even the generic AquaGiant "only a few times for experiment"
Calcium was tested with Salifer, RedSea and API so I know it's low.
