thanks denny, that makes sense.. when you say dose on alk numbers, do you mean keep alkalinity in check and correct calc as i need with the right alkalinity?

Hello

By no means am I an expert on doising as I am just about to start using ESV two part myself but check out this artical I found while reading up on how to use it. Maybe someone else has tried this aproch and can put their experience with it on the table.

That's a great point about the new salt water mix levels, as to not have variations when changing water... Didn't think of that.

What I mean is when your calcium drops don't chase calcium numbers but allow calcium to be dosed fairly equally with Alk.

Most 2 part products have the dry weight of the products already measured out for you , for examplpe your part a and your part b both have the same amount of liquid and same size bottle, but the dry weights would have been different , the idea is to replace and dose both equal amounts at the same time.

Alk and calcium are used up in a fixed ratio meaning that if you were to use up 1 dkh of Alk it would be impossible from a consumption point of view to use 50ppm of calcium , the ratio for calcium consumption is about 10% of Alk or for every 1.4 dkh drop its 20ppm of calcium and about 1-2 ppm of mg.
