R.O. vs filtered water?

I have 4 Sw fish only(F/O)tanks. 125 and 3 55g's. I converted from 100% R/O to filtered water about 6 weeks ago. Fish seem to be doing fine and it certainly saves on the water bill. Any comments on the virtue's of using R/O vs. filtered water in F/O tanks?

I hate RO system as they waste more water than they create. On the other hand, if your costly fishes die due to water condition, you're paying big bucks too :eek:
As far as filtered water goes (I suppose you have a filtering system for your regular tap water)may not take out certain substance that are not harmful for us, but deadly for fish ? :( :confused:
Thinking out loud...

I'm new to ths site and am getting a bit discouraged. It seems like responses are being directed to folks that have been on the site for some time. That kind of defeats the purpose since newer members s/b encouraged to continue to learn from more experienced fishkeepers. Maybe it's my topic that's kind of boring and mundane but water quality is the most important issue when trying to create a healthy aquatic environment. Having said all that, I'm still looking for some responses.

Julio,
I've always used filtered water with no problems. The only time my tank ever had RO water was when the lfs delivered it and set it up for me. That was 16 months ago.
I use a tapwater purifier from aquarium pharmecuticals (sp), that is intended for aquarium water. I get around 100 gallons of water from a cartridge before it starts looking bad. At that rate, each gallon costs me around 15 cents and it has no water waste.
My water is crystal clear, I have no algea problems and my fish are healthy. You can see pictures of my tank and fish by clicking the link in my signature.
I have nothing against RO and it is very good to use. However, anyone that says RO is the only water that will give you success is someone that I would have to respectfully disagree with.
Tangman :D

Thanks tangman. You have regained my confidence in this chat room. Saw your tank. Looks great. Thanks for sharing.
Re: inquiry on R/O water... It is reverse osmosis water. Basically water run through a very refined filtered element which produces close to 100% pure water free of most pollutants. While this sounds great, it is very wasteful because it dumps out about 90% of the water, maybe more, during the process. Thus to get 35 gallons of pure water , it usually takes about 24 hours and over 315 gallons of "waste" water is produced. Not very efficient and a great waste of a natural resource.

Thank you very much.....I guess you learn something new everyday. My opinion (now that I can make an informed one :D ) is that you would really need one simply because I only add tap water to my tank when I refill and top off.
Later :)

I don't use RO cuz my water bill would be thru the roof.
I use a two part filtration system.
No probs so far.

Tangman - I have a question on your A.P. tap water purifer I know it is supposed to remove metals & Chlorine. Does it also remove phosphate, silica, nitrate etc?
Julio - You shouldn't have any problems as long as you test the water and it comes out "clean" and free of undesirable stuff.

I'll paste directly from the site itself:
The Tap Water Filter has a single cartridge that removes all organic and inorganic contaminants including heavy metals from tap water. Water first passes through the prefilter pad to remove sediments. Next chlorine, chloramine, and organic chemicals are removed from the water in the "dechlorinating and organic removal chamber." Then all inorganic ions such as calcium, sulfate, silicate, carbonate, magnesium, sodium, ammonia, nitrite, nitrate, phosphate, lead, copper, and zinc are removed in the deionization chamber. The Tap Water Filter is the only single cartridge tap water filtration system that makes organic-free deionized water.
Tangman :D

i don't know about you guys but i love my ro unit, it might not be worth it to you guys but sure is to me, i have 7 tanks i use it with, but i also have a well and don't pay a bill, by the way water can't get wasted, theres always a certain number of gal. of water on earth, it's something like 360.6 billions gals. of it, and it's been that much from the begining

catch the waste water and use it for your changes; use the RO for topping off. the waste water has gone through 4 filters before being cast off by the membrane.

this depends on how BAD your water is to begin with usual number is 4 rejected to one gallon of filtered water. so to get 35 its usualy around 140 gallons and to be honest its really not all that much in cost I think my water bill went up about 5 $ a month or so.
I agree the reject water is the best thing for watering plants inside and out.
