So I dosed phosphorous from flourish as recommended morning I tested now still 0 , do I dose everyday until I read 1 ppm? And is it safe for fish shrimp?
Do I also dose Tropica Specialised fertiliser(nitrate,ammonium,phosphorus) or I don’t dose this yet because there is 10-20ppm nitrates already?
Flourish recommended is 2.5ml per 20 gallon which delivers .132ppm PO4
These low amounts are hard to detect.
24.5ml would bring 20 gallons up to 1.3ppm.
Seachem can be hard on the wallet too!
My Cory's and RCS have not melted yet!
Zorfox planted tank calculator can be downloaded to your PC.
It can resolve dosing problems and you don't need to understand molecular weights etc...
The tropica product I am not familiar with but an EI dose would require 22ml.
Based on the rotalabutterfly.com calculator.
What are your existing nitrate levels from??? Phish???
In a new tank I just dose immediately to desired level.
