Aquaforest 123

[mymarinedream]

I've just purchased the aquaforest1+2+3 and everything I read is quite clear to dose all 3 in equal amounts with the quantity determined by the alk usage of my tank. Only issue I have is my Ca is already high. My question is do I still dose?

Current Parameters:-

Salinity 1.025
Ca 540 (Hanna instrument)
Mg 1180 (Salifert)
Alk 8.0 (Usage 0.1 per day) (Hanna instrument)
Phosphorous 5 ppb (Hanna instrument)
NO3 <1.0 (ELOS)

What salt mix do you use? I would wait until Calcium is lower (400-450ppm) before dosing the 1+2+3+ - if the 540ppm is accurate. The Hanna Ca test can be difficult to do correctly due to the small sample size. Maybe cross-check with another test kit.

Otherwise, can do a water change schedule to get calcium back down (depending on salt mix), or just dose Mg and KH (not the components from the 1+2+3+, but just plain baking soda and mag-chloride) until Ca falls back within normal range.

Red Sea coral pro.
Ca comes in about 430

you’ve made me think!!!
I changed the Battery in the Hanna checker and wonder if it needs calibrating now?
Especially as tank looks normal.

There's no calibration on a hanna checker. You can buy a check standard to verify it, but there's no adjustment.

Do you know why the calcium would be high?

If you are confident in the reading, I might dose less of the calcium part to allow calcium to slowly decline, but even at the full dose it shouldn't rise more unless you are adding it some other way as well.

Someone mentioned to check the Hanna tester and turns out it’s faulty. Ca is 340. So now I’m bring it back up slowly and once there I’ll dose equal amounts of component 1.2,3

Sounds good.

Happy Reefing.
