That's good to know. I'd been treating RO Right as if it were similar to Equilibrium and using whichever was convenient. I'd noticed that when things started looking "off" adding a little extra epsom salt seemed to help.
I'm a DIY CO2 kinda gal, so I'll never reach the levels you advocate. Even so, I'm able to pick up good info from what you write. The most important being that I used to be way too stingy in feeding my plants. They do much better with the more generous levels you advocate.
For our purposes RO Right does RO wrong. It adds very little GH, maybe 1 degree. All it adds is TDS (total dissolved solids) as some sort of 'background' level of 'stuff' in the water. I'm not even sure what the purpose is.
Edit: Here's an odd thread where it appears that Seachem conceded that someone else's calculator got the calculations for K+ in EQ correct compared to Seachem's own folks. The question that remains - Was it formulated wrong to begin with pertaining to K+? Apparently EQ doses a lot of K+ in relation to everything else:
But I want to know *exactly* what I'm dosing, so I won't use anything unless it is included in a calculator that I can trust. You and Greg need to build a simple calculator for the stuff you are selling/recommending. I don't want to do the math each time, I just want to plug and play.
Greg said he used something I suggested some time ago, I know generally what is in it, but not precisely.
I know he adds less K2SO4, more MgSO4.
Beyond that, you need to ask him.
I am more concerned with having enough of Mg, Ca, which is estimated generally, so a precise ppm is not required for GH anyway unless you want to answer one of two questions:
What s the bare minumum, or what is the maximum, but the range produced as measured via GH kit should be pretty good.
So if you add 1-2 degrees more GH once a week after the water change, via this, you will never have an issues with Ca/Mg.
If you believe you do, you need to look elsewhere.
I've had all sort of tap over the years, I've never found this general and quite simple method to ever fail.
Now you might have something other than Ca/Mg issues causing your problems, but not Ca/Mg.
Mg issues have popped up but they are very easy to rule out, so we added more of that and less K+ since we get plenty from KNO3.
Tap's GH is never all Mg and no Ca, so the Ca issues are very rare.
Awesome--that's one of my pet peeves about the other products!
It was seeing it on Greg's site when I was ready to reorder nitrate that prompted the question. If I'm using this with RO water is it enough for gh or do I still need to add other stuff? I do use baking soda for kh--or just add back some tap water.
One more question (you're creating a monster)--is there info on the reactor you mentioned somewhere here at your site?
