water is skimmed 24/7 by an MTC Power Pro IV which
is driven by an Iwaki 70RLT.
As for new water, I happen to be serviced by
a well and the TDS coming from my tap averages
211ppm. This water is treated by a 100gpd Spectapure
5-stage RO/DI unit, which effectively reduces
the TDS to 0. I mix my new water in a 125 gallon
vat made by Rotational Moulding in Gardenia,
CA and keep it moving with a Little Giant pump.
I also threw in an airstone. Calcium and Alkalinity
parameters are brought up to tank levels with
B-Ionic. Room temperature keeps it within a couple
degrees of the tank. I try to keep additives
to a minimum but will occasionally add a dose
magnesium, strontium, and iodine.
Since no aspect of this hobby seems to be more hotly debated than this
one, let me just say beforehand that these are the numbers that work for
me. I am not recommending them.
S. G. : 1.023
Temp (F): 76.1-77 Degrees
CA: 450 ppm
Alk: 11.2 dKH
Nitrates: <2 ppm
Magnesium: 1200 ppm
Iodine: 0.8 ppm
Strontium: 10 mg/L
Calcium and Alkalinity levels maintained by an MTC Pro Calcium reactor
charged with ARM media. This is used in conjunction with a DIY 44g Kalk
Dispensing unit: Spectapure Litermeter.
Specific Gravity determined by a refractometer.
Test Kits by Salifert and LaMotte.
pH Meter: Pinpoint.
TDS Meter(s): Hanna & Oakton Con Ten.
Misc. testing equipment: Nikon Binocular
