new to ppm

I put 5 gallon of water in a bucket to sit. It has been sitting for 2 days. This morning I checked the ppm and it read 154. Is this normal or what should I do about it.

154 should be fine to use. i personally use RO water for hydro. that way the only thing in my water is what i put in it

oh I got cha. I will be using advance nutrients. and I have 15 gallons of water in a 21 gallon reservoir. so should I add the 154 in my total ppm with the nutes

yep. exactly. if you are really interested, request a water analysis from your city. they have to provide you with one for free.

I use 7.5 gallon tubs. We live in Nevada, terrible water quality. We use a under the sink reverse osmosis system.

When I change the water in my resivor every two weeks or so I use the 1/4" line that recirculates water into the pot and use it to empty the tubs. After adding new RO water to the tub the PPM read 100-118

Hah! That's how I knew my RO filter was bad; I was mixing nutes with tap water like I always do for the extra calcium, and on a whim I tested the RO as long as I had the TDS meter out anyway. RO came in at 110, and the tap water is consistently around 175. Went out and bought new filters the next day.

See, I thought I remembered changing them pretty recently, but evidently not. This time I got smart; I put a piece of painter's tape on the outside of the unit and wrote the date down.

OP - if you do decide to go with tap instead of RO, I second the suggestion that you get the water analysis. The geology of wherever you live will make a big difference in what minerals you have in your water. For example, if you live in an area where the geology is all limestone, your water will be high in calcium but may have almost no magnesium at all - so you'll still need to supplement your mag, and using calmag may not be your best choice because you're just wasting "PPM headroom" on extra calcium you don't need.
 
not sure what you are talking about. cyco are made from salts. bloom B is potassium nitrate and monopotassium phosphate.
Because it's a protein based nutrient, and it's pharmaceutical grade. Just because it has some salts in it doesn't mean it's salt based. There is very minimal amounts of salts, and it's an ionized salt. Check it out, you will be pleased with the results!

the only 2 ingredients of bloom B are both salts, not proteins.

not saying cyco is bad, just that's it clearly salt based.
