Mixing RO water
Hello! I have a very irritating issue. My water comes with at least 40ppm nitrates out of the tap. We’re gonna contact the water company as I don’t actually think that’s safe to drink. But I had a question about using it in my tanks.
I was wondering if it would be possible to get an RO unit, and mix some regular tap water with the RO water to bring down the nitrates. As I understand it RO strips the water of everything, making it uninhabitable to freshwater fish. It also drops the ph, which would shock my current fish for sure. I’ve read of people remineralizing RO water to make it safe for fish, but would mixing 50/50 RO and tap have the same effect? Is there any way to bring the ph of that mixture back up to where my fish are at now safely? I have a few very densely planted tanks right now, and they never get below 40ppm nitrates and water changes don’t help. Does anyone have any experience with RO water in planted tanks that might help? Thanks a lot
