Hi everyone! I have a 10 gallon tank that I am not sure what to do with, but most of the options I am considering involve a planted tank...thus, I have devised a fertilizer regime that would work (with minimal tweaking) with a fairly wide variety of livestock. How does this sound?

*MACROS (Dose 1/3rd of this on days 1, 3, 5 after WC, do not dose any ferts on WC day)
-.6 ml Potassium chloride (roughly 1.12 gm/ml, 52% potassium by mass, adds
17.6 ppm TDS and 9.15156 ppm potassium)
OR (for harder water)
-.6 ml Potassium bicarbonate (roughly 1.2 gm/ml, 39% potassium by mass, adds 19 ppm
TDS, 7.43 ppm potassium, 11.4 ppm carbonate)
-.6 ml KNO3 powder(powder is 1.06 gm/ml, about 61.386% nitrate by mass, adds
16.82 ppm TDS, 10.328 ppm nitrate, and 6.39 ppm potassium)
-.3 ml KH2PO4 (.96 gm/ml, about .698% phosphate by mass, adds about 7.62 ppm tds,
5.3 ppm phosphate, and 2.28 ppm potassium)

*MICROS (1/3rd of this dosed on days 2, 4, and 6, with the possible exception of the calcium)
-1/8th tsp plantex CSM+B (adds .5 ppm iron)
-.9 ml epsom salt (about 1 gm/ml, 20% magnesium by mass, adds 23.76 ppm TDS and
4.75 ppm magnesium)
-1.25 ml Calcium chloride dihydrate flakes (.68 gm/ml? 27.2% calcium by mass, DO NOT
mix with plantex [they react], adds [assuming above density is correct] 22.4 ppm TDS, 6.11 ppm calcium)

This was designed with a soft water tank in mind, but I could easily tweak it for harder water (adding calcium, magnesium, carbonates, etc with the water change water, for example...my tap is quite soft, so I can either reduce it to 2 ppm TDS with DI resin or buffer it to be harder). Thanks for your thoughts :)

First thing that jumped out to me was your Ca:Mg levels seem off.

But I don't know what you are starting at (RO, tap?). Or what you are shooting for for final tank levels.

Typical EI levels are minimum 15 ppm Ca, 5 ppm Mg (per rotalabutterfly). My 10 gallon hi tech tank is at 28 ppm Ca, 14 ppm Mg.

I ran at 4 dGh for awhile and experienced growth issues. Bumping up to 6, I'm slightly above that now, cleared those issues up.

Lastly, I would argue that Ca:Mg are macro nutrients not a micro. Relegated to micro status by some but none the less very important. Lol! :)

I am primarily thinking of a soft water tank, starting with 2 ppm TDS water from some DI resin. Of course, if I opt for a harder water aquarium, that would change. The calcium and magnesium are definitely important...guess I just put them with 'micros' for convenience. I can double them if needed.

2:1 ratio Ca:Mg seems to be what most, myself included, likes to run at on here.

You could start at the minimum and see what happens? Just bump up as you see issues.

I suspect the small volume of water makes things difficult at that level though. I know I have to be at 6 or I see growth issues.
