Stupid question about water

Ive been noticing on these forums that alot of people suggest you use RO/DI water instead of tap, even if you condition the tap water. What does RO/DI mean?
 
Reverse Osmosis/ De-Ionized Water.
Conditioned tap water does not come close to the quality of using RO/DI water, IMO.
By the way the only stupid question is the one you don't ask.

You can buy an RO/DI water purifier and make it yourself..which is better to do in the long run, or you can buy it from Walmart...

If you buy it from Walmart you still don't know what quality you get.
Using tap water and treating it can work for fish only --- don't try and keep corals but if you're using tap water with a saltwater tank you're really asking for problems.
RO and RO/DI filters out everything bad that causes nuissance algae to grow, can harm fish and easily kill corals --- heavy metals, phosphates, nitrates,etc.
Your water treatments treat mostly for chlorine which the RO process takes care of anyways if you buy the filter.
I always suggest airwaterice (just google it) as I've always been pleased with their units but theres a ton of good places out there.

Oh, this is what the first stage in a 5 stage filter process can remove from your tap water

My tank used to run on tap water, and all the corals were thriving. When we add salt to RO/DI water, we are adding negatively charged impurities to the water
. It works perfectly fine with corals, people are just paranoid. If you have a high TDS rating in your tap water, its worth the money, but other that that if you can't afford it, don't buy it. Seriously, my corals were doing great on tap water with a high TDS rating!

No, but seriously, get the RO/DI unit, or these people are going to murder you. It is also beneficial to the tank.

Oh, and one more thing: I couldn't keep shrimp in the tank because the high levels of copper in the water killed them, but my corals really were thriving! They are not as delicate as you think!

Ok, thanks everyone, I am going to look into that! I dont have corals, but I have shrimp and stuff, so I think I would benefit from it anyways!

Not all corals are the same some are not very tolerant to toxins found in water copper being one of them, copper can also cause higher mortality in some fish. Not all tap water is created equal, the house I used to live in had a community well and the water quality was excellent and I did use it for a couple of years. The water that I am on now is supplied by a mountain lake so in the spring and summer it has a tendancy to have high phosphates and nitrates but during the winter it is fine. So I use RO/DI most of the time but I still use tap occasionally when I don't have time to get down and get water.
 
We spend hundreds or thousands on our saltwater systems so why risk potential problems by cheaping out on water. My goal is to have the most beautiful and healthy aquarium I possibly can and enough goes wrong when doing the right things. I know there are people who use tap water and have no problems but honestly the risks far outweigh the rewards.

This hobby is a lot like car buying. If you make a big down payment, the future will be cheap and beautiful.
Don't skimp on it because it isn't "necessary," just buy one

Are we paranoid? Probably. Should we be? Absolutely.
This hobby is basically the recreating of the most complex ecosystem in the world. Snot water and sodium chloride won't cut it.
