Hey guys I knocked my 5 stage ro-di down on the floor and broke the membrane housing so im waiting on it from amazon, in the mean time running out of water I went and got 5 gal of distilled but only added two, after doing about a 10-15 gal water change, gfo change and a clean sock (200mu). I have a 75 display and about a 35 sump. I have GFO and started biopellets around 7.20-7.25 and only used about 1.5-2" of it in my phosban 150s are my reactors because they said to start low or you might get a white algae bloom i havent added any more yet. Anyway so I added the 2 gals of distilled without mixing any salt in, and I didnt just dump both in all at once i did like half a gallon at a time over 30-60 min approx. sooooooooooo in the morning and today my tank is pretty cloudy and the only thing I can think is either it was the distilled water somehow, or, the water change I did possibly was somehow contaminated? I have my ro-di in my basement and it does get some light sometimes possibly direct sunlight at times, but I try to keep it at least shaded from direct sunlight to inhibit growth inside there obviously, but I will fill a big garbage can with ro water and use it as needed, the water might be 3 weeks old by the time I use the last of it, should I always use fresh water?? The only other thing I did to try and combat the cloudyness is added a nice size bag of carbon pellets into my overflow not sure if its working or not yet,,,,,,,,,,,,,,, any ideas would be appreciated! somehow after cleaning my overflow when i put the hose back into my sock its making a bubbling/kerchunking noise im guessing because of how the hose is routed/shaped, that could be causing a tiny bit of turbulence in the first chamber where i have my skimmer and possibly tossed up a little bit of detritus that was on the bottom there so I didnt have floss in that final bubble trap slot on the far other side of the sump just before the return so I also added floss there..... just trying to give as much info as possible, all levels were perfect last time I tested even though im having more algae on the glass than usual mostlikely from slacking on water changes. it looks like it might be clearing a bit but still anyone had this issue? thanks so much in advance for your help!:hb2:

In the future I would not used distilled water. Some distilling processes can add copper to the distilled process. Although I do not think two gallons in a 75 would be a problem.

is copper not something commonly used in reef tanks?

also, if you heat water, evaporate it, re-condense it, (distill it) you leave behind all impurities I thought was the whole point of distilled..

well i got about 3 gals of tap water thats been sitting out overnite ill probably have to add before i get my ro back together

I always added distilled when I'm out of rodi with no problem and on a smaller tank .. Maybe something is spawning..

Even trace amounts of copper are deadly to corals and inverts

You are correct, but copper is often used as a condenser for the steam

If you have some Prime, adding it to the tap water can help neutralize any bad stuff

As long as you test your TDS and it comes up 0, distilled water is fine
