Hi Mr. Vegas,
I agree - it's much better for the skin (ours anyway - not the fish)
I have Culligan units. Raine is another good company. You can lease both, if you don't want to fork out all the money at one time. They can be pretty spendy.
I bought mine about 4 years ago, so don't know current prices. It was around $1200-$1500 for both. I think there was another thread about Culligans in here recently that gave the prices.
It's great for the tanks, and drinking water, if that's bad too.
If you're going to use tap water for your tanks, you seriously might want to look at getting the RO unit. I'm rusty on this, since it's been so long since I bought, but I remember that particle size was very important. If you don't have much in your water, any cheap RO unit will do. But if you're water is bad (like ours in CA) then you'll need a better unit, that can handle the larger particles. The ones at Home Depot cound not handle what was in our water. Get your water tested (Sears will do it free) and then shop around for a unit that can handle what's in your water.
I love my Culligan systems and wouldn't live w/o them. The RO unit has been awesome for my tank. I was just uncertain in your first post, if you were getting the softener for the fish, since you mentioned them. It will not benefit them at all, but the RO unit will benefit everyone. Hmmm - sound like a salesman.
