why do you want nitrates lower than 5-10ppm?Found high nitrates lately and increased the amount of % of my WC.
Did two 50% changes in two days to get it to test yellow instead of Orange. Now I do actually 4g WC but it's a 10g/w a good(2.5") of gravel
and other stuff I'd say it's not quite 9g.
But my test keep coming out about between 5-10 PPM after I do the water change and allow 30 minuits for it to mix completely.
Yes I just tested the tap water while I was typing this and it's bright yellow...not a hint of Orange.
I use the EI low light weekly doses only due to no CO2 but only Excel @
2x the normal doses.
Was wondering if you thought it may eventually go a bit farther down after the WC. I expect it to rise during the week, but since I do use KNO3 it should have enough without starting with some there before I add the ferts.
This new 45% WC is only in it's third week now.
