No3,Po4 dose

[matt199]

Hi guys I need some advice on dosing my nitrate and phosphate’s.Im daily currently adding 20 ml of No3 and 15ml of Po4 daily on a 100 gal SPS system.I am on getting a reading of 2ppm No3 and 0.03 reading of Po4 on my Saliefrft test kits.I want to turn my skimmer off all together because it’s getting expensive buying all these additives daily.Is this a bad decision or not? BTW the only filtration I have is the skimmer,filter socks and really old figi live rock.

Not a bad decision I don’t think, the only thing I have in my sump is filter sock and rock as well. I used to struggle all the time with my PO4 I started using amino acids with a couple drops a day and my PO4 is steady at 0.05-0.07
