    So I changed out my ATO this weekend and it got me thinking - if a person doesn't have a RODI unit, what are they using to replace evaporated water. I realize, or at least hypothesize, the majority of people have a RODI but thought it might be interesting to what other sources people are using/available for those that do not.

    I don't have the money for an RODI so I just buy it from the store.

    Not many options. I used to go to my local LFS and finally made the investment in an RODI. Best money I ever spent.

    I actually bought my starter RO/DI unit from my LFS as one of the first pieces of equipment for my current setup. In time I upgraded to the BRS accessories (double membrane for 150gpd; double DI unit to get the cleanest water possible). I just saved up and collected piece-by-piece, and was so glad I didn’t just plunk everything down on a credit card.

    But even with my starter unit alone, I created crystal clear water that first cycled my tank, my sump and QT. I don’t think I would have had such success with tap water...even with Prime or whatever conditioner you use.

    Sure, my LFS probably has even cleaner water, but I’m not into lugging water in my car. Besides my Neptune Apex controls my RO/DI, ATO and water changes now; so I’m not even lifting a five gallon bucket of water anymore.

    What really made me make the investment is I was having a phosphate issue and finally checked the TDS on the LFS water and TDS was 129. Shop owner claimed he had forgotten to change the RO membrane and di cartridge. That was it for me. Make sure you test the TDS on any water you plan to add to your tank.

    I buy saltwater from my LFS and top off with distilled water. I got rid of my RO/DI years ago when I took a break from the hobby. I should probably buy a new one, but I've been lazy.

    I only have a 50gpd unit that gets hooked up to my bathroom faucet. If i dont make enough on days i am home for water changes, top off of my planted and reef. I use grocery store distilled.

    Best investment anyone in this hobby can make is having your OWN RO/DI unit. I know cost may come up and when you actually think about it, you can find great prices on them. Buying water from a LFS is in my opinion one of the WORSE things you can do. LFS are notorious for having bad water quality in their displays (at least a lot of them) so I personally won't trust any water from them.

    Do you self a favor if you don't have one, find a used one on your local board. When I go to an LFS and I see people hauling in 10 - 5 gallon jugs to get filled I just honestly laugh to myself. That is one quick way to get yourself out of the hobby quickly if you ask me.

    The current percentage of people that have units should speak for itself really. 86.5% of current votes have their own system.

    I was using tap water for about 7 months and quickly switched.

    Were you growing a lot of algae?

    I agree having your own unit is a great idea but I can think of far worse things hobbiests can do besides buying LFS water. My LFS has a number of packed sps tanks with huge colonies. How bad could their water be?

    There are definitely stores I wouldn't buy water from, but not all are bad.

    But again, owning an rodi unit is a great idea regardless.

    A good water filtration system is far more useful that people realize. Yes, my RO/DI system provides zero TDS water for my ATO and water changes, but it does far more.

    Crystal clear ice cubes.
    Clean, non chlorinated (or what have you) drinking water.
    No lime or scale build up in your coffee pot, humidifier, etc.
    No more buying or carrying cases of plastic water bottles... This one was huge for me.

    Note: DI resin for daily use is impractical. Save the DI for your tank. RO is sufficient for any of the above.

    You have a good LFS then. Not a lot of places around here where you can go to the LFS and buy colonies of SPS.

    That's a fair point, maybe it's not the norm. They are actually display tanks he has, the colonies aren't for sale. He frags them often though. Most colonies are over 12"

    I completely agree with this! Much more benefit to an RODI than simply clean water for the aquarium.
