Well Water Test Results. RO/DI recommendations.

ReefDreamz · Aug 23, 2021

Hi. I'm planning to get back into the hobby after an 8 year hiatus. I figured the best place to start is with my water filtration. I'm on a well. Based on these test results do you see any deal-breaking issues? Based on these results what would you recommend for an RO/DI system? I'm planning on an approximately 180 gallon set up.

Edit. Forgot to mention I have a 30 micron sediment filter and a radon bubbler system installed already. My water pressure is about 50 psi. When the well was dug they said it was 11 GPM.

I'm on a community well in my area. I use the BRS 5 stage and love it. I'd recommend the booster with it. Comes with a built in flush valve and TDS meter. I flush for about 5 minutes before use.

What do you have for water pressure?

I would just get a basic unit and add a booster pump if you do not have at least 50 psi.

It doesn't give the units for conductivity but assuming it is tds that is fairly high. I've read various issues about wells depleting di very fast - so I would recommend an opinion from a professional.

If you're not limited by a restrictive budget get one with a booster pump and separate cation/anion di resin followed by a mixed bed.

Since you don't have chloramines in the water a regular carbon block is likely good enough.

It might be smart since you are on a well to use a coarse filter Infront of the fine filter

The gauge on my radon bubbler is measuring 50 psi. Not sure if thats my actual pressure but as far as the shower and faucets go I have very good water pressure.

The conductivity is listed as 149 umho/cm. I'm no expert but as far as I understand conductivity and TDS are related but not the same thing. I don't know my TDS but I ordered a TDS tester so I will soon find out. I forgot to mention I do have a 30 micron sediment filter already installed.

I run off a well with high tds. I have the 7 stage w/ booster pump and am making enough water for water changes on 17 tanks (100g a week give or take). I have been amazed at the longevity of the individual filters.
