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.


This pump from amazon is what i sent the bossman, what do you think about it?

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? :o
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.

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.
