Here's a calculator that will help you


I use it for my EI dosing for my 55 gallon tank, and here's what it gives me for mine

KNO3 - 2.546 grams 2-4 times a week
K2SO4 - 3.48 grams 2-4 times a week
KH2PO4 - 496 micro grams or .5 grams 2-4 times a week
MGSO4 - 10.556 grams 2-4 times a week

and I use Plantex CSM+B for my micros - 1.549 grams 2-4 times a week

But I prefer to dose dry fertilizers because it's easier to manage the exact amounts needed.

Now here's my weekly dosing regime

Mon-Weds-Fri - KNO3+K2SO4+KHSPO4= Macro's
Tues-Thurs-Sat - Plantex CSM+B= Micro's
Sun - 50% water change

45g Long - High Light Planted Tank / 30g - Plant Grow Out Tank / 100g Tank - currently resealing

I've never been clear why people don't simply dose dry. Seems like an unnecessary complication otherwise.

29g high tech, 10g low tech halfmoon, and please see my 5g crescent journal.
