Recommendations for booster water pump.

[Melquides]

I have been fighting high ppm from our RO unit. We have Well water, it comes out over 1500ppm and after 2 prefilters and The RO unit still hangs around 300-350. When we put this system in and noticed it slacking, i did ask the bossman if the low PSI had anything to do with the high ppm, he said he didnt think so, I figured he knew what he was talking about.

After struggling with our flower room, and now coming up on wk 8, seeing signs of Nitrogen over abundance, im nearly certain a chunk of that ppm is Nitrates. Who knows what the rest is, could be high in Calcium for all i know, Calcium doesnt play well with anyone if it is in excess.

Water psi going into the RO unit and pre filters totally matter.. I am just learning hydro, and this 350 ppm to start has been a wrench in my gears i did not need.

Can anyone recommend a solid booster pump i can throw inline before the filters, im looking for at least 60-65psi to make these filters do what they should do.

How many filters do you have pre-RO and what sizes are they? How long has it been since you replaced the membrane in the RO?

https://www.amazon.com/Hydro-Logic-31027-Pre-Evolution-Pre-Filter-Evolution/dp/B004LO0HBS Two of the pre evolution filters. then the Evolution RO. These filters are nearly new. we have only ran them a month and a half tops, they have never preformed proper. it just took me a while to realize that low pressure could cause the high ppm coming out. Only getting about 20 psi to the RO unit. I cut the prefilters out, as a test, and it went up to close to 40psi, i saw under 200ppm coming out for the first time.

These two run to the main RO unit. the pump if i understand things correctly should go after the prefilters and before main RO unit.

are you in the US?

i just bought a 1/2 hp inline booster pump from harbor freight to water my lawn. i think it was $99. i have a 300 gal container and with this pump, my sprinkler works like a champ. spray gets a good 20 ft in the air.

OMG, 1500 ppm and you don't have a water softener?
My water is 650ppm/1.3 EC, I installed a softener before I even moved in!

1. A Softener Protects an RO Unit:
Reverse osmosis membranes are fragile. Although there is usually a small sediment filter in front of the RO, reverse osmosis has a hard time removing or reducing calcium and magnesium–the minerals that make water hard. So by installing a water softener WITH an RO drinking water system, the water softener or conditioner will reduce the water hardness, thus acting as a protective barrier for the RO system keeping it from fouling and extending the life of the membranes.

Reverse Osmosis Vs. Water Softening: Do I Need Both?

If you have a water softener in your home, you may feel pretty good about your water. But in fact, even after being processed by a water softener, impurities may remain in the water you drink and w…

Water softeners do not treat water for drinking purposes. A water softener is good for the home's plumbing and water-related appliances.

OMG, 1500 ppm

my well is only 400. 1500?? does a spoon stand straight up in a cup of water??? lol.

We decided to try this one. 4.5 gal per minute. 70 psi. Hydrologic makes one specifically for our RO unit but it was 10x cost. I will check into softeners. And yeah 1500ppm straight from well, it is high.

Made some pretty buds, but man they are small. I figure 1. I did some overfeeding. 2. High N in the water, and who knows what else, 3. Hard to control conditions. I hope to do better next time. Cutting new ones this coming week.
