E.I. Dosing and a loss of N03
I have a 40b, ADA AS, 2 e-90 LED lights, press. c02, sump, and a 150 sqft cart filter. I have made a few changes recently regarding ferts and lights. i have never had an issue before with algae until now. I can't seem to get my n03 level up. i am already adding about double the n03 suggested and still it will not test in water after 24hrs, is this normal.
Like i said i am new to dry ferts and used liquid previously following the one pump per 10 gal directions
the ferts are from GLA
