Completely agree - [emoji1305] explanation!! I try to keep my nitrates between 2-5. This sometimes means no dosing for days and then occasionally I'll need to dose 2-3 times a day.
No3 consumption varies like crazy, so auto dosing doesn't work - I find the key is just to add little and often only when it's needed. Flourish Nitrogen works a treat for me! No algae problems thus far - 2months in and mega colours and growth.
Can you share how do you dose Flourish Nitrogen. How many mls? How often? What is your water volume? What is your nitrate target? I have started dosing 3ml in 90 gallon of water and don't really detect any increase in Nitrate after 12 hours (redsea pro test kit). I dose every other day. I am hesitant to increase the dosage. Would love to hear about your experience. Thank you in advance for sharing.
