How to bring PPM down?

Nutrients

In the context of the discussion we wondered if his tester was off. So reading distilled water was a thought to see what it said. If he gets 300ppm on distilled water then his tester is wonky.
Thats all I was looking for.

Soak the probe in distilled water for a half hour or so and try again! Or a storage solution.

@Spiney_norman @Audiofreak @Borderryan22 @Tylersays @Myfriendis410 assuming my tester is accurate and my PHed reading is over 700, is that to high for my seedlings? Is there a filter system I can add to help bring the PPM down?

What is the reading of your water, alone, no pH, straight from the tap?

You should have to chew that water. LOL i could be wrong but it seems too high to be accurate.

Under normal growing conditions you are only concerned about the ppms BEFORE adjusting the pH.
If it really is that high you will either have to filter it or buy/obtain filtered water.
If you want to just try it on a seedling and see what happens that may tell you a lot.

That’s not unsafe levels, but that is real high straight from tap.

Maybe check out the water reports on nearby towns.
My town is only a couple thousand people and posts a report. Its a well water town.

@Spiney_norman I have very heavy lime build up. Without my hard water system my dishes come out of the dish washer with powder on them.

So you have a lot of calcium.
Water softeners do leave salts in the water that buildup in soil too.
You might just have to look into an RO filter system. If only for your physical health.
But your plants will love it too.

I have this. Been using it for 15 years.
New Pre/post filters every 6 months.
New RO membrane every year or every other pre/post filter change.
Cost around 200 per year to operate.
