Seachem, why are you doing this to me?

3 days of filling my RO/DI Brute for a water change this weekend and used Dose_planted Seachem's own dosing calculator to figure out the proper dosage of Equilibrium to take 40 gal. of water from 0 to 4 degrees GH. It said 128 grams. Seemed like a lot and so I dialed back to just 100g and STILL got a reading of nearly 12 degrees Gh.

What in the world did I miss?

Incidently, I also used Baking Soda to raise the kH from 0 to 4dkh and nailed it right on based on the 1 teaspoon per 30 gal calculation provided by some in this forum. But I can't water change with 12 GH.

I think you entered in the wrong number. Notice the unit is meq/L. 1 meq/L is 3dGH. So if you want 4dGH, you need to enter 1.333 meq/L.

Doing that, I get 42.6 grams.

Seachem's calculator asks for desired GH in meq/L, not in dGH! Download Zorfox's calculator (Zorfox's Planted Tank Calculator) - it can calculate pretty much everything (except for KH).

This. I agree the calculator is misleading. I doubt I would have noticed that to be honest!

I am adding that actually. Audionut suggested it via PM and provided a few chemicals. What would you like to see? I know most want baking soda but do you want dKH added to every chemical that can change it? That's what I was thinking.

Developers are good at crunching numbers and making software work. They suck at making applications that make sense. Users are good at telling you what you did wrong and what they want! I'm all ears...

IMHO it'll be good to include potassium bicarbonate, sodium bicarbonate and calcium carbonate. Last one you already have available for Ca and GH calculations, so KH option can be added as well. Potassium bicarbonate should probably be available for calculations not only for KH but for K as well - it adds quite a lot!

As for bugs, the latest feature, nutrient accumulation calculation, is not yet working properly in some scenarios (e.g. try dose frequency 7 - once a week, and WC frequency also 7 - results are really odd). It looks like as if water change and addition of fertilizers are happening on the same day then calculator assumes that water change will always happen after addition of fertilizers. I guess some people may do this (some of the people who do daily dosing) but IMHO more common scenario is to first change the water and add fertilizers after finishing with water change (or have new batch of fertilizers mixed into water used for change). At least this is definitely more common if WC and dosing schedule is the same - what is the point of dosing the water you are going to throw away? May be this should be an additional checkbox (WC before dosing or WC after dosing if they happen on the same day)? There are also minor layout glitches if font in Windows is set to bigger size (125%, 150%) - this is very common on laptops with small high resolution screens: right part of the main window is cut off (unless program window size is manually increased), "About" dialog content doesn't fit and gets scroll bars. Auto update doesn't work even if run as administrator.

But overall this is the best calculator available by far! And it is still under development and improving, progress is very noticeable! Thank you very much for this wonderful tool!

Yeah, indeed. I'm looking forward to using it in the future!

I don't know if this will be of much help to you, but 1 tsp. of Equilibrium in 5 gal. of RO water gives me a GH of about 5-6 dkh. For KH I add 1/2 tsp. of http://smile.amazon.com/gp/product/B0064GZPU4?psc=1&redirect=true&ref_=od_aui_detailpages00 for about 5 dkh.

I will be adding several soon.

Edit:
I added,
Calcium Carbonate (CaCO3)
Potassium Bicabonate (KHCO3)
Sodium Bicarbonate (NaHCO3) aka Baking soda

Fixed. You can now select to dose before, after or not at all on water change days. Setting the water change and dose frequency the same displays correctly now.

I added a scaling routine that should fix this issue. If not send me a PM and we can track it down.

Fixed
Update should work fine now. You still may need to run as administrator though.

Anyone know which of those three Seachem Alkaline buffer is? I have always suspected it is just baking soda but there is nothing on the label to indicate what the contents are.

While this isn't exactly on topic with the main title and OP I thought I'd put it here to see if I could get an answer before starting an entirely new thread.

I'm starting to use the EI method of ferts.
How long can the mixed fertilizer solutions be stored at room temp?

indefinitely. You might see fungal growth in the micro ferts solution, but you can add a few drops of excel to combat that.
