I hope it is ok to post it here, wasnt sure if it s newbie or general?, feel free to put it where you want.
I am new here, Hello!
I have out of the Wall.
EC at 25 °C μS/cm 735
pH- 7,4
O2 mg/l - 9,0
total hardness °dH - 17,1
Carbonat hardness °dH - 9,4
Base capacity (KB 8,2) mmol/l - 0,27
Acid capatcity (KS 4,3) mmol/l - 3,4
hard water
Calcium mg/l - 108
Magnese mg/l - 8
Natrium mg/l 36
Iron mg/l 0,01
Mangan mg/l 0,02
Ammonium mg/l none
Chlorid mg/l 50
Cyanid mg/l none
Sulfat mg/l 145
Nitrat mg/l 1,0
Nitrit mg/l none
Fluorid mg/l 0,10
Bromat mg/l none
So thats not good, especially considered the amount of calcium in it.
Right now i use Hesi Cocos in Cocos which works ok so far, not great, but ok.
Later on i want to switch to GHE Maxibloom, like that its good for Hydro and it is nicely concectrated, less to carry arround.
Right now i think how to deal with the Water.
3 Options
1. take it as it is with Maxibloom and may go a little lower EC then normal, 0.2-0.3 maybe and let it go.
2. using a Waterfilter who changes a part of the calcium ions to magnesium ions, so EC would stay similar (may 0.1 lower) but there will be more magnese then inside and less calcium.
(there are several types of this filters, most change calcium to natrium, useless for us, but one type does it to magnese instead of natrium, this one i would test)
3. going for a RO osmose unit, there is no problem to afford one, more that i dont watn to have such a thing in my kichen somehow, ugly clunky, slow, pain to use
(i have no, RO Waterstation nearby, best would to carry it from homedepot, lots to carry, lots waste, not my favorite option).
Goal is to get some usable Water for ok to very ok results and get some stable water ph wise.
So far i can say the Tap Water is at least quite easy to PH down and relative easy to keep within the 5.5 to 6.5 range, probably
cause there is so much calcium in it that the GHE Phdown powder never runs out of buffer.
I would really welcome some thoughts of you guys, in best case someone dealt with a similar water, GHE Maxibloom and a DWC (probably going for a 9 Gallon DWC for one plant, later on).
