I'm not quite sure how to total the nutrients but I'm dosing 15-20ml of Leaf Zone and 3-4ml of Flourish weekly.
The easiest way to total the nutrient levels in your tank is to use a nutrient calculator like this one:
for a 4ml flourish comprehensive dose it gives you:
In my opinion the absolute minimum levels you need for the above macro nutirents is 5ppm MO3, K 3ppm, Ca 2, and everything else at 0.5ppm. Many people dose more that 10ppm NO3 1ppm PO4. In short for macro nutrients you want everything a 1ppm or higher. You are deficient on all of your macros.
The situation is no better for the micro nuitrents with the exception of Fe, Cl, an Mo Those are OK. The rest are still too low. Zn and CU are extremely low. Fortunately most homes have copper or brass pipes that leach copper or zinc into the water. Seachem is assuming your water will basically assuming your tap water 90% of the needed nutrients.
For your Leaf zone it will drive you with:
If we use the same fertilizer calculator for Nilocg.co Thrive fertilizer with a 5ml dose we get:
As you can see the levels are much higher. Thrive doesn't have calcium and is a little short on Magnesium,sulfur, zinc, and copper but most tap water is rich in these nutrients. The remaining micro nutrient levels are also much higher than what you can get with your current fertilizers. if you dropped the leaf zone and upped the Flourish comprehensive dose to 40 or 50ml you might get good results or you might kill your fish from toxic levels of iron. At a dose of 50ml you bottle will not last long. Thrive will last a lot longer.
