As many tanks are different, they also change through time.
So adding more might be required later or after a rescape etc.
So say 3mls per 100 liters daily may require 5mls per day later.
Do not assume that one amount/rate is enough all the time from then on.......
Many do........
I tend to add a bit extra just in case.........it makes figuring out complex variables far far far easier...:idea:
But these are traces.........so the demands are very hard to follow as the plants just need a tiny amount and a little storage in the vacuole can go a long long way before we see any negative IMPACTS. effects can be subtle and hard to be sure what you are seeing is really Traces, or perhaps a little variable in the CO2?
They are also very tough to measure with test methods and determine what is limiting vs non limiting as far as plant growth. Most use dry weight left overs for tissue analysis. But that just compares micro grams of Fe between two plants, and that needs correlated with relative growth rates between then samples to suggest that the plant is limited.
Lot of work.
Maintaining good non limiting nutrients other than traces is required and you need at least 3 weeks time and be sure that no other limitations are present.
That's not as hard, but still takes work.
But the tank looks nice as a result too
