I have a goal to get a fully planted tank going with moderately high lighting, EI & CO2. I have a tank spare approx 22 usg. I would like to use straight tap but I fear the problem with the water is its high GH 180dH with deficiencies in K unknown & Mg 0.1mg/l.
When I read the plant adds it seems there are conflicts between ideal light and or water requirements. Do you select your on plant mix water parameters KH & GH?.
Possible Planting
Hemianthus Callitrichoedes and / or Glossostigma Elatinoides / Micrantheum Umbrosum
Sagiteria Lileoptris,
Echinodorus Tenellus
Could all these be started emersed (style.) what is the recommended planting density to achieve a carpet of plants?
Dimensions 79(l) x 27(w)x 37(h)
Lighting 2x 24w T5 1x20w T8
Substrate 1-2mm quartz gravel over JBL Aquabasis Plus
Decor Rock & drift wood branches
3-4 weeks terrarium
Add water.
EI ferts.
Temp 20-240C
Jewel internal filter
DIY CO2, pressurised or yeast? to be added via powerhead
Would cutting with RO then adding a GH boost be a better alternative to boosting the tap deficiencies and further increasing the GH.
Are specified hard or soft water plants adaptive to non ideal conditions?
How much Mg should be added to avoid deficiency in the plants, 10mg/l?
What is the relative composition of GH boost (Ca/K/Mg/Fe SO4), would adding a recommended ½ tsp per 100ltr of GH boost add sufficient Mg?
Or knowing that I have more than enough Ca but unknown K will dosing tap with Epsom salts for Mg be sufficient with a small increase in GH.
Is there a relationship between Conductivity, Total hardness and TDS?
On adding Nitrate & Phosphate nutrients, if 17.8ppm = 10dH should we see a rise in GH of “Xâ€0dH would this be an equivalent to a rise in TDS which can be read to1ppm?
Here’s the data
Local Water Parameters given by South East water company
GH = 17.60dH
pH = 7.4
Ca = 125.9 mg/l
Na = 28.9 mg/l as Nitrate, chloride or Carbonate?
K = ?? mg/l as Nitrate, Sulphate or Carbonate?
Mg = ?? mg/l as Sulphate?
B = 0.1mg/l
Mn = 2.0µg/l
Fe = 34.0µg/l (unusual max reading affecting average, low value is 12)
Nitrates = 23.4 mg/l
Chlorides = 42.7 mg/l
Sulphates = 49.2 mg/l
Phosphates = ?? mg/l
Total disinfectant = 0.3 mg/l
Conductivity = 652.3µs/cm
“Total hardness GH†given by water company is
CaCO3 = 314.8 mg/l = 314.8 x 0.056 = 17.60dH
Mg by calculation [Ca x 2.497 + Mg x 4.188] x 0.4 = Ca CO3 mg/l
{314.8-[125.9 x 2.497]}/4.188 = 0.1
Mg = 0.1 mg/l (very low, PCV of water authorities can be up to 50mg/l)
Adding 0.1gm/l MgSO4 would raise GH by 0.60dH?
If carbonate hardness KH the difference between Total hardness & Permanent hardness
Total Hardness = 314.8 mg/l
Permanent hardness
Nitrates = 23.4 mg/l
Chlorides = 42.7 mg/l
Sulphates = 49.2 mg/l
Phosphates = ?? mg/l
Total Permanent hardness = 115.3 mg/l
KH Carbonate Hardness = 199.3 mg/l = 11.20dH
PH, KH & GH measured at tap with test kit would approximate to values given by Water Company.
Any advice welcome
