I have a 40 gallon tank with 72 watts of CFL and about 2 bps of pressurized co2. I am currently running the co2 and lights for 6 hours a day with co2 starting and ending an hour earlier compared to the lights.
I would say my tank is light to medium planted and I have about 12 different kinds of small fish in there.
I wanted to start dosing fertilizers.
I was going to follow this formula is that the correct one to follow?
40-60 Gallon Aquariums
+/- 1/2 tsp KN03 3x a week
+/- 1/8 tsp KH2P04 3x a week
+/- 1/8 (Trace Elements 3x a week)
50% weekly water change
To do the mixes I was going to do 500 ml bottles
Bottle 1 - Trace
I want to target about 1/2 ounce of liquid per dose which would mean I would use 1 tablespoon and 360ml of water?
I want to target about 1/2 ounce of liquid per dose which would mean I would use a 4 tablespoons of KNO3 and 1 tablespoon of KH2PO4?
Based on my lighting should I really be using 1/4 ounce of the liquid?
Part of my confusion is there is a lot of threads linking to "dead" calculators. I did find one at http://calc.petalphile.com/
but based on 40 gallons and CSM+B with 360ml and 15 ml dosing I would need 28 grams of powder which I believe is 2 tablespoons or double what I calculated. So wasn't sure why there is such a difference.
