Is there some sort of advantage of using the PPB version over the PPM? I thought to myself, maybe just get PPM (Phosphate) version, this way I don't have to calculate the Phosphate conversion. If there is some sort of advantage, I can't imagine what that would be. The only thing I can think of is that the PPB version came out first then the PPM version was later developed to help people avoid doing the manual calculations.
I agree, the Salifert is so much more cost effective than Hanna. It's also really easy to use and really accurate
Okay, I'm just now learning about soda ash and bicarbonate. I thought you were referring to kalkwrasser. After looking at the BRS web page, I see what you're saying now. They're basically alkalinity but different source of them. The only thing I've ever used for Alk is ESV B-Ionic 2 part and kalkwrasser so the other two you just mentioned are foreign to me. Interesting. I didn't know there was anything besides 2 part or kalkwrasser as a way to dose Alk.
Yeah, I guess there is no sense of using 4 vials for N and P Hana testing but that's good to know lol. When you say that you're rinsing with tank water, do you mean the vials or the graduated cylinder? If you're referring to the vials, don't they have to be squeaky clean to make sure it's the right amount? Yes, please do post a few pictures whenever you have some free time on your hands showing what you mean by that, I would certainly appreciate it. I get what you're saying about using the graduated cylinder but still don't understand what you're rinsing the tank water with.
I should really get one of those D-D true seawater refractometer. And also the TM high precision Hydrometer. I do remember someone telling me not to use the Red Sea's refractometer and that it's not really designed for seawater. Thanks for the reminder! Good call.
