Fish Crazy
Is it feasable for someone with 2 ten gallon tanks to look into an RO water unit? What is a reasonable price per gallon to pay at a store for this?
MY LFS wants a dollar a gallon for RO water.
A ~25gpd system costs about $120. Toss in another $20 for initial set up and another $10 for water conditioner to put in the stuff you need that RO takes out and you're looking at about $150 up front. If you change a total of 4 gallons a week that means that in about 38 weeks the RO system will pay for itself. Even at your low usage rates an RO system will pay for itself provided it lasts even just a year.
Just remember that you'll have to condition the water to give it some buffering capacity and essential minerals for the fish. Either cut it with tap water to get a higher than 7.0 but still acceptable pH or use an RO water conditioner.
How is RO water different than distilled water? Or those thingys in the grocery store where you put your jug in and hit the button and it gives you water that is supposedly going through some super crazy filtration methods.
