    Tell me more about micro bubbles... I've hear their name before, but never understood what they are or why they are bad.

    This is exactly why I want one.

    The one I was considering (for just the fish room) has a max flow rate of 2GPM. I think I might have to consider a larger one, b/c I have a lot of tanks.
    yeah that would be gawd awfull slow if doing more than a few tanks.........

    yes I mix hot /cold as needed to the tanks for small changes, otherwise I have storage for ro and tap.
    I have my ro going cold into a 55g drum then let it heat with aquarium heater.
    I have my water pressure at about 55 -60 psi so that's probably why I get hotter water than you would.
    I really don't know how you could hook one up for your use, but there are point of use tankless ones you could look up. I know mine needs a certain flow rate before it will work too, so that might limit you.

    when the water in the winter is colder it doesn't release the gasses as easily as warmer water, so when some of us add water from the faucet to the tanks we get millions of tiny bubbles that cloud the water, it's not so much the bubbles you see, but the very very small ones can cover the gills and block 02 and the co2 being released from them can also burn the gills. not a scientist, just what I have been told!

    thanks Jim, I am going to look into this. Getting a pump to handle the required flow rate is easy enough, but if the heater needs a certain PSI to operate properly that would be a bit costlier in terms of a pump.

    Let me know what you come up with, I think your better at researching and detail than I am. I get an idea and try it, I take the easy way! I think it is flow, gpm that effect it, not pressure.

    My fish are at my shop . I don't have a on demand heater where I live. I installed it in my petshop and grooming shop as I used to run out of hot water to do wcs and I couldn't do wcs and wash
    Dogs
    .now we can wash 15
    Dogs In a row and fill tanks with a separate hose and never run out.

    Hey April,

    I got three Sammy's I can send your way for a good wash and groom But seriously, washing dogs would be alot less demanding then the constant flow of filling 14+ tanks. My situation becomes a bit more complicted as I use RO on all my tanks, water here is terrible for discus, not too mention I run a water softener for the house. Although, perhaps it might be feasable to get a good sized one of these and then have it do dual duty, both for the house and the fish tanks as it would be pretty easier to flush the tap water from the heater (no tank), All it would take is dual input valves on the heater that I could alternate between tap and RO.

    nice idea i never would think to run RO storage thru a tankless water heater but would probally work good with the right pump might try dual outputs to so ur not pumping ro thru all ur un flushed pipes

    Just a spigot at the output side should work.

    I have a tankless water heater in Minneapolis and it also acts as a boiler to heat the house. But beware, mine cost $10k for the unit and another $10k for installation. Of course, my electrical cost is almost nothing now.

    On my current setup i am using a tankless heater dedicated for just heating my aged water from room temp in the basement (72 deg) to 85 to then add to the sump for water changes. The unit i have will flow 2.0 GPM and heats 55 gals in 12mins. I use a Pan World pressure rated pump to push water from the drums to the heater and back, and also to move the heated water to the sump. There are pictures on My Tank Journal under Sweet Water Reef.
