He says it much better than I could.
I use the one in here listed for my tank size/w a modification to the list. I would suggest you use the dry dosing first till you find out how your nutrients are
working. You may need to make adjustments like I did. Then once you know it is working, you can make the solution of it. Hard to adjust the solution.
You can get what you want fairly easily but making a duplicate of that will be impossible once you have started using from the bottles.
Almost forgot...I only use one of the three doses per week because of not having injected CO2 which this list is made for.
However I divide the Micro part into two doses and one is the next day after I dose the Macros, then skip two days, then dose that other half of the Micro dose.
This gives through the week coverage on both because the iron in the Micros is only available for about 2-3 days in the tank.
You can simply elect to do two doses of each at the recommended amount, but separated by a couple of days in order to raise the overall level of the nutrients
if you find it to not be enough/w only one dose per week or you can learn to adjust the size of the individual components of it.
