Ro unit vs lfs supply vs tap water

Hi Just trying to figure out if its worth using ro water for a marine aquarium fowlr setup.

I live in Ireland and the tap water has no nitrates or phosphates the only problems would be trace metals and chlorine in the water.

If I decide to upgrade to corals can I just use ro water later on down the road or will there always be trace elements in the water.

Should I decide to go down the ro route is it cost effective to get my own ro unit or get my water from the lfs
 
you can use tap water... but you will most likely have algae issues, most reefers use RO/DI because of this but for just a fish only just RO would be good

I would and have my own water unit it saves me money.
happy reefing!!

I would just get the ro unit now.

It is only a small additional cost and if you ever go reef tank you'll always

be glad you have it already. Also as mentioned in the previous post you will

most likely have algae issues no matter how pure you think your source water

is. Good Luck and don't take shortcuts in reefing!!!:D
 
and just because this is an irish posted thread:) I will add a joke;)
An Irish man walks into a pub. The bartender asks him, "what'll you have?"
The man says, "Give me three pints of Guinness please."
So the bartender brings him three pints and the man proceeds to alternately sip one, then the other, then the third until they're gone. He then orders three more.

The bartender says, "Sir, I know you like them cold. You don't have to order three at a time. I can keep an eye on it and when you get low I'll bring you a fresh cold one."

The man says, "You don't understand. I have two brothers, one in Australia and one in the States. We made a vow to each other that every Saturday night we'd still drink together. So right now, my brothers have three Guinness Stouts too, and we're drinking together.

The bartender thought that was a wonderful tradition.
Every week the man came in and ordered three beers.

Then one week he came in and ordered only two.
He drank them and then ordered two more.
The bartender said to him, "I know what your tradition is, and I'd just like to say that I'm sorry that one of your brothers died."

The man said, "Oh, me brothers are fine----I just quit drinking."
 
+1 to getting an RO unit. I have a fish-only tank and decided to go with RO to reduce algae issues. I initially bought RO water from my LFS. After doing that for a few months, I installed an RO unit. It's SO much more convenient (and cheaper).
 
You could get a TDS meter and see what your number is, but that wont tell you if there is copper. And the tests for copper are not precise enough to tell.

I bought a RO/DI unit after my second trip to the LFS for water. I ran the numbers, and based on the water usage of my 20g tank, it had paid for itself not including costs of time or fuel. I also like the control of knowing where your water came from and how pure it is.

I'd agree with that evaluation. I've seen LFSs use tap water and sell it as purified. It's cheaper to pay some kid to clean the tanks than use quality water.
 
I used tap water and just added water conditioner. but that was before I (re)discovered my old RO/DI machine.
just use tap water if you're short on cash and save up for a RO/DI unit. they're worth it.
 
Advice and jokes what more could I ask for :beer:

I think I'll get the ro di unit how difficult are these to setup do they have to be plumbed in permanently or can I take it out when I need to do a water change.

It would be more convenient to use tap water but as someone said already it would be a short cut.
