My calcium is around 300 and alk at 8 dkh. I want to bring the calcium back up to around 420. The B-ionic that I have says that's it's concentrate and I can't find a similar jugs for sale online.
According to all the reef chemistry calculators I have tried I need 1500 ml to get the calcium back up. I know that I shouldn't bring it up more than 50 ppm per day but even if I quarter 1500 ml it's still 312.5 ml a day. Which is equivalent to 1.3 cups and that just seems like way to much to me.
I have a 180g display with around 35g sump (DIY). With displacement I'm assuming it's around 200g total volume.
I did do a 10% water change after work today and after I tested it didn't seem to change the calcium levels much. Of course this was right after the water change.
Any advice about using B-ionic or how to bring my calcium up would be much appreciated.
