Thumbs up EI Dosing Group Check Requested

I've got a 75 gallon tank with 2x external filters (XP3, Mag350), timer based CO2 with a glass drop checker, flourite and 12x10W LEDs that are run around 50-60% of max at present. Decently loaded and fed with BN plecs (25+ juvis) and 30-40 neons, platies, barbs and cats. Good on algae at present. Anubias, java fern, crypts, marsilea ground cover and a few stems.

I've got a marine magic 3 head peristaltic dose pump. One for KNO3, one for KH2PO4, one for trace. GH booster (P added) added weekly @ WC at the rate of 2 tbsp. Baking soda for KH.

I'm working toward changing the fert jugs every ~105 days (based on max speed pf 0.5-0.6 ml/sec, 2 minute run time and my three 2 gallon fert jugs). Should have a pump life span of 16+ years.

Using the 60-80 gallon EI dosing chart, I'm looking at a weekly dose of:
  • 2.25 tsp of KNO3
  • 0.5625 tsp of KH2PO4
  • 0.75 tsp of trace (Plantex CSM +B)
Divide by 7 (days/week) and multiply by the 105 days from above and I've got a dose of:
  • 11.27 tbsp of KNO3
  • 2.82 tbsp of KH2PO4
  • 3.76 tbsp of trace (Plantex CSM +B)
So my questions are:
  • Does that look right?
  • I've got muratic acid from Lowes, how much should I add to the fert bottles (esp. the trace) to prevent mold build-up?
  • Other thoughts / comments appreciated


Thanks in advance!!!

Your dosage math looks correct. However, depending on your plant composition, required dosage levels may change over time. You may want to start with this system, then tweak according to how the plants respond.

The amounts you posted don't seem very accurate. Here are the amounts for full EI dosing from this thread.

15ml/75 Gallons

KNO3 115.7 gm (approximately 22 1/4 teaspoons)
Plantex CSM+B 72.5 gm (approximately 16 3/4 teaspoons)
KH2PO4 17.6 gm (approximately 3 1/8 teaspoons)
Optional: K2SO4 47 gm (approximately 7 1/4 teaspoons)

Sorry. I've never used muratic acid as a preservative.
