Advice? How much 2-part do you dose

How much 2 part (BRS) do you dose? *tank size? *what type of tank? sps, soft,...

 

I test mind weekly and use the seachem cal to fig out how much I need

 

Seachem - Reef Fusion

 

I have notice polyp extestion on a few coral since I been doing this and dropping my nitrates way down

 

90 gal , fair sps load with a little lps. dose 85ml a day each of brs 2 part to maintain alk of 8.5 and calcium of 420.

 

I dose 60 ml Cal and 50 ml Alk daily. I also dose vinegar saturated Kalk in my ATO water. 180 SPS dominant tank.

 

Before my tank tried to crash I was dosing 100ml of each part of BRS.
I also do 3 gallons water change per day so that helps replenish some.
Tank is 120 display, 70 gallon display and 40 gallon frag tank. All SPS.
