I have 4 dosing pumps which pump out 1.5 liter / hour (meaning 0.42ml/sec)

My tank is 126 gallon (incl. sump) which means i have to multiply the mentioned ammounts by 6.3. I also have high lightning > 3wpg.

This would mean i have to add to 1 liter of RO water:

* 378 grams KNO3

* 63 grams of KH2PO4

*0 grams of GH booster (since my GH is perfect in the water)

Add 5 mls of this solution daily.

Add TMG at 15.75 mls daily.

However, on the calculator, i've read that only 36g of KNO3 can be dilluted per 100ml.

**Question 1:**

Is my assumption correct that i could also do this:

* 60 grams KNO3

* 10 grams of KH2PO4

* 0 grams of GH booster

Add (5*6.3=) 31.5 mls of this solution daily.

Add TMG at (2.5*6.3=) 15.75 mls daily.

**Question 2:**

Is anybody familiar with the fact that KNO3 and PO4 don't mix together in 1 sollution, e.g. do they react on each other? or even better; is it better to separate them (2 different dosages)?
