water is maintaining the light green/cloudy look, been trying to keep my FC in the low to mid 20s, lowest test I got it dropped to 19, but mostly around 20 to 22. CC fluctuates from .5 to 1.0 PH staying steady at 7.2, When I did my CYA test sunday it looked to me to be between 55-60. FC been in 20s since friday. Theres just been very little to no improvement, I know I need patience cause the water was very nasty, but with my CYA test being borderline 55-60 is there a chance the low 20s for FC just isnt quite enough? this afternoon I bumped it up to 30, think it will be ok to keep it there? and also theres just been no change in pressure on my gauge, water flow is very strong
