K I will try that. Certainly couldn't hurt.

So as it turns out that de-ionization filter is for the "Hydro Logic 31023 1000 GPD Evolution RO1000 High Flow RO system". I own the "Hydro-Logic 31040 300-GPD Stealth-RO300 Reverse Osmosis Filter".
I'm seriously starting to consider renting a water softener for the shop.

Just to make sure I understand this correctly, a water softener will basically exchange the cal/mag for sodium and than the r/o system can filter out the sodium easier than the cal/mag? Is that right?

Personally not aware, I use the same 300gpd you do and I get down to 0.0ec. Can you switch your filters? Or use the different ratio tube on the ro system? I know water softeners use salt soooo not sure.

You mean new filters or different ones? Even with a brand new system, I'm still left with 0.5EC(250ppm) after running through the r/o.

I would try a new logic filter or before that, turn the knob on the back to flush the system

What I'm saying is that even with brand new filters and membranes I'm still stuck with a 0.5EC.

Yes that’s correct,the membrane won’t have to work as hard...and r/o water is never 0.0 ec..only distilled water has zero Ppms..just changed all my filters and am reading 0.33 ec

Ok perfect. I'm gonna try out a couple more strains first and if things don't straighten out I'll add the water softener and hope that does the trick. Thx for the help.

When I was in the city I had 450ppm tap water and no problem growing in it but seems to be a different ball game out here in the country.

Hey Raider - you can use the DI filter for your system too, since it is "after" the RO. take your output from your 300GPD and plug it into the DI filter, and the output from your DI filter goes to your reservoir. Here is a pic of my holding tank and how it is setup. Try this first because the couple hundred or so $$ for the DI filter might be your cheapest option. You might want to get a TDS before after meter like I have in the pic because a) it will tell you when your RO filters are bad and b) tell you when to change the DI filter. Here are the links for what I got.
Inline TDS:
DI
One thing you may need to do is step up or step down the tubing as I am not sure the output hose size of the 300GPD unit and if it is the same as the ro1000. But that is like a 2$ piece of connector and some tubing.

Before I had the DI unit I used to use my ozone generator and put the O3 air stone against my submersible pump at the bottom of the holding tank for 20 mins. This was after i had made the RO water. Then run it through a cheap carbon filter to the reservoir. The reason was some things are soluble in solution like Manganese and wouldn't get filtered out by RO. Using the ozone precipitated it out of solution and then the carbon could remove it. Anyways the DI filter seems to do the same thing I am having great results whereas before I was having similar problems to yours.

Ok good stuff, thx Karl, I'll give that a whirl and see how things go. I'll probably shoot ya pm when I get started on it if that's cool?

Sure dude. No prob. Amazon seems out of the DI kit but Cannapro will have it for just as good or better price. Call them to order though because their online site is down.

Oh man, I just re-read your earlier post where you say your post RO is 0.5EC. This filter lifetime in your case would only be 18,750gallons/250PPM (0.5EC) = 75 Gallons. So it is not going to work for you, it would work in the case where your post RO is lower. In your case a softener is the best like other people have suggested and then maybe you might need a DI as well. A softener will make your RO filters last longer too. Don't want you wasting your cash on a DI when the filter is only good for 75 gallons in your case. Don't want to be spending 70$ every 75 gallons.

Yikes, good call. Glad you caught that, I was gonna order that stuff on Monday.
I'll stick to the original plan: I'll try a couple new strains and if things still aren't working out I'll try adding the water softener.

Yeah, my water was so bad I have to use the softener plus the RO plus the DI. My buddy has the same well geology and his Manganese was 100x the EPA limit, so I expect mine is the same. The softener helped reduce it and the iron content big time (I saw the before and after lab results) as well as swapping calcium carbonate and lime/mag for sodium. In my case it wasn't enough though and I needed the DI post RO, so you might be in a similar situation, hope not for your sake.
