All For Reef question

[cable guy]

So I have a 20 gallon nano tank with a auto top off, my question is I plan on putting All For Reef in my RO/DI container which is 2.5 gallons, how much All For Reef would I need to put in my 2.5 gallons so it would be sufficient to help my corals? It usually tops off once a day..

Not to be blunt…. But read AFR instructions and use math….. depending on your top off volume and the amount you add to it you should be able to figure out your dilution in top of water and go from there. Better yet, just dose a daily amount at full concentration per instructions as required by your system and simplify things.

Do not use any AFR unless you know that alkalinity has declined below your target level.

What is you alkalinity now?

I can help guide dosing if you know the alk.
I recommend dosing AFR by alk demand. That is how I and many others do it. In 18 gallons of total water volume, 10 mL of AFR will raise alk by about 0.9 dKH.

You might have AFR mixed with kalkwasser, but we don't use AFR that way. Its all based on your test results and how much your corals consume, it takes a lot of testing to get it dialed in. Suggest that you do more reading on this, its complicated.
