Alk, CA & MG Uptake Question

[Mike810]

System Overview

360 gallon DT
378 gallons net volume

Alk 7.8
Ca 460
My 1395
Ph 8.06-8.38

I have 20 + acro frags in my tank. I do awc at 3 gallons a day with redsea salt blue bucket. I had to turn off my carx several weeks ago due to parameters rising. The frags were also added several weeks ago. I am wondering if 3 gallons a day awc can really supply the demands of 20+ acro frags all 1+ inch.

I haven't dosed any alk/ca or mg in several weeks, just the awc. Do these frags really consume that little alk/ca and mg? They all have color and they're encrusting, I just thought they would have consumed more where I'd need to run my carx. I also have several torches, hammers and frog spawns.

Can a 3g/day AWC supply all their demands? Possible, but not likely. However, with almost 380g net volume it could takes weeks or longer before you could see any net shortage on a test kit. And that is assuming they are all growing well.
