Apisto-plants balancing act
I haven't decided whether the best answer to this problem is going to come
from an apisto-phile or an aquatic gardener. Probably someone who is both,
but maybe not, so I'm taking the liberty of double-posting.
I live in Garden City Idaho, the closest thing Boise has to a suburb, and
indeed it probably qualifies. We have less than 10,000 people, but draw our
municiple water supply from nine different wells. The water leveles in the
local aquifer go down in the summer and fall, and go back up in the winter
and spring. The local geology is also quite diverse, and so as the water
department switches around to the various wells, and the water in the aquifer
rises and falls, water parameters vary. Sometimes I can use peat and other
things to get fish to spawn, sometimes I can't. So I finally splurged and
bought an entry-level de-ionizer.
Now I have this really clean water, and can adjust the electrolyte levels to
<60ppm GH and <90Ás conductivity. But I want to provide a reasonable
nutrient level for plants, also. I have the Homegrown Hydroponics "six-pack"
and it seems I should be able to build my own electrolyte mix and PMDD
formulas to meet the plants needs at the restrictive TDS limits necessary for
the fish. For those not familiar with the sis-pack, it contains:
1)Calcium nitrate (CaNO3)
2)Potassium sulphate (K2SO4)
3)Potassium nitrate (KNO3)
4)Monopotassium phosphate (KH2PO4)
5)Magnesium sulphate (MgSO4)
6)Trace minerals mix, with Fe, Mg, Mn, etc.
Percentages by weight are given with each one(in the really fine print), but
one of the kids carried off my magnifying glass, so I'm going to have to wait
until I find or replace it to mix the exact ratios of stuff.
Can someone take a shot at mixing some or all of these into useable formulas,
one for water re-constitution, and one for a fertilizer used every couple
days? I will be making pH adjustments using HCl, unless something on this
list will draw it down to 6.0-6.3 as part of the re-constitution thing. I
wont be injecting CO2, and light levels will be fairly low.
Thanks in advance,
