sump return

Tunze 7320 Turbelle/speed control
Seio 820
I ran an eductor off
my sump return for quite a while, was happy with it. Took it off
for a visual change a few months ago - might go back on sometime.
Additional Equipment:
100w Tronic Heater
40w UV Sterilizer
No additional mechanical/chemical
filtration used at present.
Calcium/Alkalinity demand
met through combination of store-bought 2-part Calcium/Alkalinity
suppliment and Randy Holmes-Farley's
DIY 2-part solution.
Levels are generally kept
at:
Calcium: 400-425 ppm
Alkalinity: 8-10 dKh
While I test Magnesium,
it has generally not been an issue for me, and it's been 6 months
since I've supplimented.
