Congrats John! Your thread has had over 17800 views!!

Thanks Josh.

so i picked up a TDS meter today, and i tested my tap water, and it came out to be 160-165. i am guessing its not the best or the worst.

so after starting up a few RODI threads, and then bailing on the idea, I got one put aside at red coral for me for thursday pick up.

It will be another week before i have to do a water change, so i guess well see.

John good for you. About time. The tap water at my end of town is aroud 179ppm and after the RODI 000 ppm. Trust me it is a good investment.

yeah, gotta move forward eh.

wow john thats crazy. ive always had RO water, accidently put five gallons of tap water in my tank one time and wow did i ever get some algea

Your tank pops with colour now wait until it gets the good water.:biggrin:

John do yourself a favor and get kevin to bring in a timer switch for your rodi unit too. I had 2 incidents involving overflowing rodi water in my laundry room until I got one. No problems since :mrgreen:

I use one of these in my RO/DI reservoir in the basement.

Does a good job of cutting the water. Although, I wouldn't rely on it 100% of the time. If you know you don't need to make RO/DI for a period of time, it is best to completely shut off the supply water to the RO/DI. This will prolong the life of the filters.

+1. Use the float valve shutoff as a flood preventer when filling a reservoir, but don't use a float valve shutoff kit to regulate the RO/DI full-time. That's a lesson I needed 3 RO membranes to learn. :redface:
