Usually the threads I see are in the opposite order. I'm currently using straight RO water I get from a water store. I bought myself an at home system and once I saw that it was about 1 gal RO to 5 gal wastewater I couldn't believe it. I'm just not sure I can continue to do that in the middle of a drought.
However, my tap water... well it sucks.
Last night pH 7.4 on the high range API kit and 7.6 on the low
Tonight after letting it rest - 8.2. Ouch.
I run at about 6.4 - 6.6 right now with pressurized CO2.
Thoughts on pH up/down products? Don't think I like the idea, but I don't really know what's in that stuff.
The water is HARD at 19 GH and right now I'm at 5.
If I attempt to transition to full tap, what should I expect from my plants and fish? I would have to go slow mixing in tap with each water change as that's a huge jump. What do you think my pH would run at? A lot of my plants and fish prefer softer, more acidic water, at least so I have read. Am I risking losing fish and plants?
The tank I am talking about is the 120g in my signature.
Any help or guidance, experience, anything ya got would be appreciated. Kind of at a loss. Totally don't want to do it, but would enjoy skipping all the trips and money to the water store, and San Diego would be saving some precious water. I just don't know.
