RO question/advice

[tim the toolman]

I have my waste restricted to about 50/50 with the fresh and I do not notice a reduction in production. Your system may be different though. I have been running it this way for over six months and I am still getting 0ppm and about 400ppm on my waste (or should I say laundry) water.

if it is a straight RO unit, you won't get 0 TDS, you need RODI

is 2 or 3 ppm acceptable for aquarium setup?

It's not that bad, I doubt even those running ro di are changing filters at 2ppm but if your not goin to shoot for 0 ppm 13 ppm out of the tap isn't really that extreme either.

Really, 13 ppm is the same as 2ppm?

i'm setting up a 120g so waiting for the stuff to produce is a PITA...

if that's the case would you recommend that the juice is not worth the squeeze?

I am not nearly as knowledgeable as others on here but it seems others are holding off on commenting. Put it in perspective, my tap water is over 100ppm so I use ro/di. But at 13ppm I personally would just fill the tank and add prime to remove the chlorine and chloramine and then just let the tank cycle as you should anyways. Then for you top offs once the tank is up and running it may be worth the ro but 13ppm seems very low. Again this is just my opinion.

Just tested a cup of tap water and it came in at 162ppm.

I already have 30g produced so i think i'll continue to use the 2ppm....

it cant hurt and the extra time i leave it mixing with the salt will probably be good for it....
