Yea I have one on my water on the ice box. LOL I use it for few of my breding tanks. It sets the water primes at.
/ 60 to 80ppm at times. That depends on how much I use it. I've got a in line filter by culligan/ sediment filter, Softener a ladie gave me a few weeks back. I just havn't put it on the line. Lazy I guess. LOL it reduces alka,lime,carbon.chlorrian, and a few others I can't re menber. Would that help? str8 from the tap my water is some of the hardest in the U.S.
/ 300ppm to 225ppm
There is one thing going for me in this area. That's that the state of Texas no longer can dose water with chlorian. I tell you what. I've been wanting to do this for a while now. So if i really what Discus I thank I'll do it today sometime. I'll go by my local water treatment plant and get a read out of my water.
That's a good place to start don't you thank? LOL
