Hi All,
Been lurking the forums for a while, but had a question around EI dosing and was wondering if someone could sanity check my approach.
Tank is 172L with monte carlo carpet and s. repens carpet covering 90% of the bottom, with a small area of dwarf hairgrass.
I've just flooded after doing a dry start so I have really well established root systems.
Running injected Co2 sitting at ~42ppm according to KH/PH calcs, but im reducing this to 30ppm.
I put together the below chart based off of what i've purchased for dry ferts and what is spat out of rotala butterfly + a lot of online reading.
Couple of questions:
Cheers,
Chris

Couple of questions:
- Are my PPM targets reasonable? I used pretty much the upper limit as a starting point with the aim to reduce over time
- From my (rotala butterfly's) calculations, dosing to hit No3, Po4, and Mg target PPMs leaves me with only 46% of the required K is this right?
- Should I up my KNO3 dose to hit a No3 of 30ppm and get closer to the 30ppm K? (from calculations this should get me to ~67% of target)
- I cant find many target ppms for trace minerals / micros with the exception of Fe do my below numbers look okay?
target ppm | PPM | Dose | Daily Dose | |
KNO3 | 100.00% | 5.61 | 1.87 | |
No3 | 20 | 20 | ||
K | 30 | 12.61 | ||
KH2PO4 | 46.13% | 0.94 | 0.31 | |
K | 30 | 1.23 | ||
Po4 | 3 | 3 | ||
MGSO4 | 100% | 10.00 | 3.33 | |
Mg | 10 | 6 | ||
Mg (From Water) | 4 | |||
EDTA Fe | 100% | 0.66 | 0.22 | |
Fe | 0.7 | 0.5 | ||
Fe (From Water) | 0.005 | |||
AG Trace Mix | 0.46 | 0.15 | ||
Fe | 0.7 | 0.2 | ||
Fe (From Water) | 0.005 | |||
Mn | 0.1 | |||
Zn | 0.02 | |||
B | 0.02 | |||
Mo | 0.01 | |||
Cu | 0.01 |
