Yes it reads 2.8 but 10 ppm for tap water is unheard of that’s almost ro water

It’s deff calibrated correctly do you use blue lab?

So is 10ppm my tap water then. Like I said above it’s a brand new pen out the box and when put into calibration solution it reads 2.8 every time. Do you think maybe chloramine has something to do with the reading?

Do you have town water? There should be a public water test online for your area if you're in the USA for you to check out ( if on town water)
be aware sometimes when they flush you will get extra sediment in the water it is good for a guideline to know what is actually in it

Water: The Most Essential Compound | Rollitup
I really liked this thread. It got me into how it is good to start with good water, as alot of things in growing really come down to really controlling the variables and tweaking them. I use reverse osmosis water but I am thinking of trying a grow with just town water to see if it makes a big difference or not. RO comes out at 0 and you don't get a real pH reading with it either so always add your stuff in the proper order or whatever and mix it good and wait to take good readings. PPM and pH meters will help alot

Your tap water has very low electrical conductivity, be grateful. Also keep in mind, non-ionic particles like sugar will not be detected by a tds meter.

Why are you measuring hot water?

Thank you man it just seemed extremely low to me. Another question is because it is so low what’s the easiest way to get rid of chloramines which I do have unfortunately.

I’m not intentionally measuring hot water just happened the water was a bit hotter when I ran it out the tap.

Just use your water the way it is, it’s fine.

Chlorine will dissipate after being left out, chloramine will not.

chloramine 3-4 weeks it will be gone( yes your right aeration is best to remove) ,what does it do to plants nothing it will/may make the ph in soil change over time thats it ,if that happens adjust as per normal... theres a few studies out there ,

You'd need to add Cal-Mag with readings that low. I think my RO is at 10.

Blanket statements like this are not always correct. It's going to depend on the nutrients he uses.
