When you initially setup the Trident and run the initial calibration, it does waste a bit of reagent (if I recall, it was about 10-5% of each for me). If you've run the calibration a few times that could possibly explain some of the discrepancy. As you progress through the month you'll find that usage of reagent A picks up a bit.
That makes sense. If you don't mind me asking what do you run your alk at? While trying to do some research on what to do I had read somewhere that you would only use twice as much of reagent A if you run higher alkalinity. I keep my alkalinity around 8 so mine isn't real high.
Not at all. My alkalinity fluctuates between 8.5 and 8.9. It always drops down a bit in the evening and recovers during the day. According to my Apex Trident I'm averaging around 8.7 alkalinity. This range seems to be the sweet spot, yielding a PH between 8.0 and 8.1.
Ok so your alk is higher than mine but not by a lot. I tend to keep mine toward the lower end of what is commonly considered an acceptable range because my system is fairly low nutrients so I'm trying to avoid burnt tips on my sps.
I have a little bit of everything but I've gravitating toward sps recently. My collection of corals increasing is what finally made me decide to get an apex/dos/trident.
You can also try recalibrating your Trident when you open your next box of reagent. Note the numbers of the white container (this is what you'll have to change in your calibration settings).
I just did my initial calibration about a week or so ago after letting it run for close to a week. The only difference it made was correcting my calcium levels. Before calibration my calcium was reading about 100 higher than it actually was.
So do you add the leftover reagent A to the new bottle, or do you just reset B and C (I am assuming resetting them in settings tells the trident they're full again)?
