tap water

Good question this. Is RO water good for freswater tropicals??

Since I have been keeping marines I bought an under the sink RO unit with faucet tap for the family (tastes great by the way, can't drink tapwater anymore, uugh!!). Produces upto 500 pumped litres a day into a pressure storage vessel (100litres) so have RO on tap constantly.

To sum up, is RO good for freshwater tropicals??

Is produces

PH 7.1
Nitrate 0
Nitrite 0
Phosphate 0
Ammonia 0
Chlorine 0

Or in easy terms 0.03ppm

Our tapwater is 450ppm

Legal limit is 750ppm

Boston, Massachusetts municipal water:

Test Results
pH: 8.4
kH: 3
GH: <2
Nitrate: 0

Municipal statistics:
pH: 9.3
kH: 2.2
GH: <1
Nitrate: 0

Great water, but for the pH. I have no idea why they crank the pH up as high as they do. It's 6.6 at the resevoir before treatment.

Littleimp, make sure you buffer the water tho. Your RO water prolly has little to no KH so you could be looking at massive PH crashes. Sounds like good neon/cardinal tetra, angel, discus water (I'm obsessed with neons and cardinals, I wish I could afford RO
