Hello,
I am not sure if someone else has tried this before, but I am dosing PPS-Pro in a garden pond to try to make plants healthy and control/get rid of the algae there (fuzz algae mainly).
I have CO2 injection which gives around 15 mg/l (between 15-20 mg/l) during day (7:30 am to 20:30). I stop it by night; I can't afford to waste it, I have to keep CO2 in 3100 liters with several cascades and fountain, which I want to keep running.
The direct sunlight hours, now, are 7, from 11:30 to 18:30 more or less. But it is different from an aquarium: the sun moves, changes intensity, color temperature and trees and other things cast moving shadows around. The depth is around 65 cm.
I began with PPS-Pro several weeks ago (I aim for water column values of No3 = 10, PO4=1), to my surprise it seems to work. I have to add 1 mg/l No3 daily, as PPS-Pro says, but PO4 I have a daily consumption of 0.5 mg/l, and not 0.1. But I have another problem with the micros:
I use Seachem Flourish plus Seachem Iron (ferrous gluconate, I still have 2Kg of Fe gluconate...). The problem is the cloudy water (thus precipitating and losing PO4 and Fe as insoluble ferrous phosphate) when I dose them together (or with 1 hour of separation, it's the same).
The problem is how can I dose iron, as I don't want to wait until PO4 is 0, as I think this could lead to problems (I would have oscillating PO4 concentration in the water column, from 1 to 0 then to 1, etc), which I think would not be convenient.
EDIT: My pH when CO2 is running (normally) is steady 7.1-7.2 (w/o CO2 it raises up to 8-8.3 at evening, but this is no more real as I have CO2 all day).
How can I dose iron by keeping 1 mg/l of PO4 in water column?
Thank you very much for any help !
