In reference to my high tech, somwhat high light 95g.
I did not conduct my last water change for about 2 weeks, maybe more.
Although I am not dosing ferts daily, I have a dosing regime that is not really structured.
I use Seachem Iron and Potassium, and I also have a pre mix Macro and Micro.
After a water change i may dose a couple capfuls of Iron, then the following day I will dose a couple capfuls of P.
After a few days, I may dose my Macro and Micro in the same day, reaching the end of the week.
This more or less repeats itself, and not nessesarily in that order for the following week.
I suppose I have two questions here, if my nutrients are being consumed regularly, and I am not overdosing, then what benefit is the large weekly volume water change. (In reference to ferts only) ie, I do not need to reset
the system, rather than maintain the water quality.
Second, if there were deficiencies, I would expect growth to slow, and the plants to start telltale signs, instead of algae (of which i have no problem)
Is this always the case?
I appriciate the broadness of my question.
