CITY TAP WATER?

[revarejay]

Just got my blue Lab meter in yesterday and tested my water PH and PPM. I'm currious if I need to use RO for my current culture setup if my PPM is reading 120 (500 scale) at a PH - 7.

Mine's about 105ppm (with a pH of 8.9), been using it for years w/ no prob. Did you calibrate your pH meter?
-good luck

 

[revarejay]

yeah I did. It was pretty easy to calibrate. I need to buy their kit to clean and calibrate it every month however. I was thinking just letting the water sit with an air stone in it for 24 hours might be enough. Just add nutrients and then PH down...

Agreed 100%.
I did have a waterfarm though, and that was a nightmare if i didnt change my res every 2-3 days.
I wouldnt worry about calmag either. Itll only make your water harder.

does your water have chloramine or chlorine in it?

chlorine you can bubble off but chloramine you can't.
either one will kill beneficial bacteria if you are planning on using them

I use tap water (current avg. 120ppm / 7.4 pH) with great results. As rkymtnman says, you have to be aware of whats in the water if you run bennies. I run sterile so its never an issue.

To answer your question...your water ppm and ph looks like you're good to go with it..

I started doing some research on this earlier today. I noticed some people have a break down of whats in their water. Could I gather this from my local water company or is there a way I can test specifically?

You can request a summary from your water Co.

yep, they have to provide you a free analysis

 

[Tim1987]

Great advice guys!
Know exactly whats in your water.

here is what my water company gave me see what you guys think...

Just do a little searching online. See how much of each is safe, and match it to what they gave you.

My tap will be different depending on the month and which reservoir is feeding my home (they say it could be mixed if required due to demand). I get 210ppm in Winter usually with PH 8-8.6. Works fine but I like to mix it with RO to bring the EC down a bit.

 

[ThaMagnificent]

My tap goes up a whole point every 12hrs so I use RO. Tap comes out at 120ppm too...

I use my well water it’s 200 ppm mostly calcium been using it for years dwc, rdwc, super soil it’s been good no issues.

I have hard water 230ppm mainly calcium. I've used GH hardwater nutes and don't have as much fluctuation in pH. The regular base nutes I have to monitor a few days after mixing then it will level out after pH adjustment.
