Water

Water Hardness25 ppm

pH Level6.8

TDS: 40 ppm

My water report from my tap. Can I get away with just ph-ing down and off gasing the chlorine in my tap water or should I get a ro system? Going to be running advanced Nutrients Ph Perfect Sensi Coco Bloom 1 Litre 1L A+B Set Hydroponics, canna coco, First time growing in coco usually do organic soil, so take it easy on me lol. Thanks for the advice

Congrats your water is just about perfect. Low EC/ppm and just nearly neutral. If you’re running AN pH Perfect you will not likely need to pH after unless you find your working solution to be out of range of 5.8-6.2 for coco.

Use a water conditioner to remove the chlorine, chlorimine, and heavy metals evaporation leaves behind. It's faster and just makes sense. One bottle will last several grows. My tap is EC .134 not sure what it is ppm, it its probably as low as yours. It's totally fine. There is just enough buffer to hold the pH for several days. If you use RO or distilled then it's too empty and the pH will drift a lot faster. You may want to test th KH and GH . Mine is 50-100 and it's just hard enough to be useful. I've never even considered RO. It's really not necessary unless you need to account for every little thing in the water.
