Here on Long Island the water is so soft, it's limp.
I have tried to glean info from prior posts, but have gotten a bit confused.
If someone can help the mathematically impaired....
55 gal - 2.9w/g 5000K 90cri
gH, kK, dH = 0
using NaHCO2 for kH [ currently raised to 3 kH for buffering of HP CO2]
CO2 40 bpm
using MgSo4 and CaCl [ found at the 4th a pool supply $10/7lbs. Sun chem co.]
Q1: what amout of Mg and Ca each would be added to a solution, such that each mL would elevate the gH 1 degree. [ that way I can figure out my own dilutions.
tried Chucks's calculator, but Ca not supported yet.
other dosages per 55gal
0.25 tsp KNO3 => 4.12ppm NO3
> 2.6 ppm K
1.25 tsp KCl > 18.88 ppm K => 21.48 ppm K
2.00 tsp MgSO4 => 5.14 ppm Mg
???? tsp CaCl => ???? ppm Ca
Q2: amounts of NaHCO2 to raise kH, so that I can do better than the add and measure technique?
125 gal; walmart-K/L covered in PlaySand;
Rena Filstar XP3
6x85watt HO flu. 4.08 Watts/gallon
3x 6500K + 3x 5000k 8hrs/day
HP CO2 ~50 bub/min into Rena canister
My Tap H2O = 0% NO3; 2 Gh; 6.8 pH; 0.3 ppm Fe
