View Full Version : My house has copper pipes - am I in trouble?

As the title states, my house has copper pipes. Am I in trouble for setting up a reef tank?

OK, I'm not too bright it seems as I've been looking at the pipes in the basement all along and not "seeing" them. Have set up an RO/DI unit, working on an in-wall 130 gallon system, and was standing there thinking about how to set up a drain and sink in the fish room. Thought "well, I can run another copper pipe from the inlet here to the corner there......" and then it hit me. DUH, copper not good, copper bad.

Suggestions? Advice? Brain tonic ideas?

I recommend using an RO/DI system to purify the water first. :)

I have an RO/DI unit that I'll be using. Will this be enough?

That should be fine, as long as you use a good TDS meter regularly to check the status of the filter.

OK, I can start breathing again. TDS meter, PH meter, and refractometer already waiting for use. Thanks for your assistance.

Sounds great.

Good luck. :)

Stupid question. What is a TDS meter? I am in the process of buying a house and it has copper pipes.

TDS = total desolved solids

tells how pure your water is.

You guys have any recommendations for a TDS meter?

hana is a good brand. IMO

ok, my turn for the stupid question. Is this what the "red light/green light" unit is that came with my Spectrapure RO/DI unit? A TDS indicator of some sort? If so, how reliable do you think it is....... I have a conductivity meter (American Marine Pinpoint). Can this be used instead to test RO/DI?

IIRC that shows the TDS creep. IMO worthless as your always gonna have TDS creep unless it runs 24/7.

if that is the light your talking about. does it go off after a few min.? if so then it is.

I use the PinPoint conductivity meter, and it seems fine to me. The HM COM100 has gotten good reviews, and I intend to try mine out soon now.

I used the red light/green light on my original spectrapure system for nearly a decade. If you have it set to the most sensitive setting, and read it when the system is running, it is a fine way to judge the time to replace the DI. :)

I now use a more sophisticated system from them with four in line meters, and like it better, but the lights do work OK. :)
