waters

I have drinking water filteration system at home, but not sure if its ro or di or rodi. If its a drinking water what would it normally be?

Also could I just use drinking water to do water changes?

 

You could always test it but i bough that it is a true ro di system take a pic of it if u want

And trust me i am telling u this from expecrience rodi will save u from alot of headaches in the long run trust me

 

if it is in the fridge it is probably just a filter but if it is separate then it could be ro but probably not di. the only real way to test it is use a tds meter =]

 

if its drinking water its not di it could be ro though. ro/di is the best route to go. if you can get a ro/di unit and a quick sink fitting. make water for the week and store it (water change water , top off water )

 

Describe your drinking water system, give us the brand name and model or post a picture of it and we can give you more accurate information.

Generally a drinking water system is RO only and if it uses a pressure tank and faucet is probably not good for a reef tank since it will suffere the effects of what is termed TDS creep. You will also find most drinking water systems do not use the same micron ranges or quality of filters as a reef system. Yes you can add a DI filter to a drinking water system but it will go through DI resin like there is no tomorrow.

 

withought having to buying ro/di unit, would Ro water change be bad? Will this water kill the livestocks?

 

A properly maintained RO system should remove 90 to 98% of the TDS in the tap water and will always be better than tap water. The key is in the words "properly maintained". A RO system which has not been maintained can actually be worse than tap water.

By that I mean you need to keep up with the 6 month replacement schedule on the prefilter and carbons and do an annual disinfection of the complete system according to the manufacturers recommendations.

The best way to tell your water quality is with a handheld TDS meter, about $20-$25 at most hardware stores like HD and Lowes.

RO is better than tap but it takes the final DI stage to get it where most people would consider it reef quality. The RO only should be at least 90% better than the tap water then the DI resin removes the remaining 2 to 10% of TDS or contaminants the RO and carbon missed.

 

di water is not recommended for drinking. there a few reasons why. google it. the chance of it being di are not to great

 

so would it be okay if I just keep changing water with RO water?

 

RO will be better than tap water but a little lower quality than RO/DI or distilled. In many cases RO by itself is sufficient but everyones water conditions are different so there is no "one size fits all" answer.
Using RO certainly will improve things if you have been using tap water up to now.
