Calcium Question/Help

[xclusive252]

Ok I am using a Vertex RX-4 Calcium reactor I set up about 1-2 weeks ago and I have a steady Alk of 9.3 for about the last 4 days of testing but my Calcium keeps dropping it was 375 and now its 355 thats after 4 days. What should I do? Im not sure if the Calcium will increase and its just the reactor breaking in or do Add Calcium to the tank?

Cal is a little out of balance vs alk. Hand dose the calcium back up to a normal level.
Balancing is done with hand dosing. Maintaining the level is the cal reactor.

What reactor media are you using? I have no issues with ARM course.

So I tested today after adding 100ml of DIY cal the same day and my cal today is 390 and my alk is 9.3 and my mag is 1395. I will test again tomorrow to see what happens

Once you get it balanced, for every 1dkh drop of alk, you should see cal drop 20.

Its 1meq/L (2.8dkh) to see a drop of 20ppm calcium...thats why its so hard to see the drop in calcium.
