my well water goes over 8 for a ph... I find RO to be my soft water fish's friend

I’ve been using R/O water for six years now and I have my own R/O unit too , a 75 gallon a day unit . The unit doesn’t seem to up my water bill and changing out the filters at regular intervals is no hassle . I mix tap and R/O to get the 100 PPM TDS that the fish seem happiest in . pH always stays the same at 8.0 no matter what I do and it doesn’t seem to matter to my fish so I don’t worry about it anymore . The only fish I use straight tap water on is my Guppies and Platy’s . They like that 200 PPM TDS and so does my ever increasing population of Ramshorn snails . One thing that happens every May and June is that with the snow melting in the high country and the river coming up is that my water comes out of the tap at 50 to 75 PPM TDS and then it gradually increases until winter sets in again . Before anybody harshes on me for letting the bypass water from my R/O unit go down the drain I don’t feel like that’s a bad thing . It goes right back into the Yellowstone River and on downstream to other towns that draw out of the river . That’s better than what I flush down and no , that’s not why it’s named the Yellowstone .

I would just get a 300gpd ro/di filter so you can stop worrying about where the water is coming from.

Good catch. Sorry. I was reading the similar thread section and not paying attention to the dates. Newbie mistake. I have over 25 years of experience in the hobby but just started using the forums to reply last night. I'm just trying to give back after all these years of taking without participation.

I have a 400 gpd so called direct flow RO unit. For my water supply it does need to be pumped. It claims to waste less water. It takes up the same space as my previous 50gpd system. Well actually less because there is no tank. Its still not fast enough to use directly without filling vats but it no longer takes me the whole weekend to prepare next week's water.
This is the one I have. I chose the dental rather than home because I did not want to remineralise. Once the DI filter was depleted I simply replaced it with a carbon post filter. Filters are around 6 months old and at present what's coming out is around 5ppm. Its over 400 going in. I typically use around 300 litres / week. With 400+ppm in the tap we also use this as drinking water.
