A month or so ago, I had some metals in my tank detected through ICP, around the same time my parameters started to drift all over the place.
I’ve since fixed the metal issues, having found three root causes and detoxed my tank back to where it should be, but my (dosing) parameters are a complete mess now and I don’t know how to fix them.
Ca 470
Mg 1520
Alk 8.1
Its a fairly new tank (9 months) and only have 9 acro frags, 2 monti frags and 2 acans.
Wait for it...
To maintain those parameters I’ve been dosing for a month now:
0.9ml 3 & 4 each (Alk)
0.9ml 1 (Mg)
0.1ml 2 (Ca)
It's a 200L total volume system (dt&Sump).
If I increase Ca, it flies off the scale very quickly, one day of 0.2ml and I’m at 490+
Other than Mg being high and ideally should be lower, my issue is I cannot get my dosing anywhere close to be aligned.
I know it’s common to not have to dose all 4 equally all the time, but the massive difference between my Alk and Ca dosing is weird.
My Ca doesn’t drop, it’s quite happily sitting around 470 for a couple of weeks now.
I fear this is a self fulfilling prophecy, whereby dosing unequally, I’m in fact causing the issue, but I don’t know what to do, if I increase, it goes off the scale.
