Kinda expensive as a ph up
You can get all the effects of silica with 1ml and a drop of ph up
[FONT=Arial, Helvetica, sans-serif]One ml per gallon of Protek yields 8ppm of Potassium and 21ppm of Silicon.[/FONT]
x5= 40ppm K & 105ppm silica.
Thats a lot
It's not that easy running MB. I got a choice between the 5ml of protekt or 9ml of potassium hydroxide ph up. More K or more P, pick your poison
I'm still experimenting with the mix, I'd rather keep the protekt lower, like 2-2.5ml. just for the cost
