Do these nutrient levles look okay?

68g K2SO4 + 68g KNO3 + 4.54g K2PO4 / 1500ml of DI H2O

300ml in 120 gallons should give me:

N: 20 ppm
P: 25 ppm
K: 2 ppm


50g CSM+B / 1000ml of DI H20

70ml in 120 gallons should give me:

Fe: .5 ppm

M,W,F = Trace
T,TR =NPK
Sat= Rest Day
Sun= 50% WC then NPK

Dosing every night after lights off for that day.




I looked over some of my previous calculations and I think I was adding 2 ppm of Fe!!! and not nearly enough Nitrate.

Do these levels look okay? Did I make a mistake in the math? I used Chuck's calulcator for everything but the Phosphate.

Tank currently has 3x96w 6700K PCF ( can run one more 96w) with 10 Hr. Photoperiod, 2xFluval 405's pointed at the plants, and Injected CO2 at approx. 4 bubbles/sec going through a "power reactor" from aquarium plants.com witch is located next to both intakes of the Fluval's, 10 Hr. areation at night with power head injecting air.

Plants: Lots of Giant Hygro, Swords, Pygmy chain sword, java fern, stargrass ... heavily planted

Fish: 10 Juvi. Discus, 10 Pygmy corries, 10 bronze corries, 3 skunk loaches, 1 Hores face loach, 3 otto cats
