Need help understanding phosphates
Since my phosphates are always at 0, this week I've decided to increase the amount macros I'm dosing.
For the past 4 days, Every day in the morning I add
P - 0.42ppm
PO4 - 1.3ppm
NO3 - 7.5ppm
N - 1.5ppm
K - 5.3ppm
Then I test the water in the evening... About 8 hours after adding ferts. ....And my phosphates are holding at 0.
Also worth noting that my nitrates stay at 5 consistently between water changes.
My 20gal tank is getting towards what I would call heavily planted... At least on the high side of moderate planted. It's medium light with CO2
So, I have to assume my plants are using up all the available phosphates? Either that OR this is an expected result when testing 8 hours after adding.
Which leads to my main question... Should I be dosing even more? Is it beneficial to have a steady phosphate reading?
