Gannon Posted July 28, 2021 Share Posted July 28, 2021 Hello! Because of my tap water having obscenely high ph (9.5+) as well as many other issues I have had to use RODI water. This is fine as I've been doing it for years at my previous home which had similar but less extreme issues. Point is, when I use Seachem's alkaline buffer, equilibrium, and acid buffer on new water to get the parameters to 7.2 ph, 4 kh, and 6-8 gh, it always comes around to about 350-400 on my TDS meter. I keep fish like denison barbs, rainbows, corydoras, honey gouramis, bettas, and soon clouded archerfish. Will this be an issue for any of these fish in the long term? Haven't had issues so far after moving to this new location! Thanks for any help that you all can offer! Link to comment Share on other sites More sharing options...
Kat_Rigel Posted July 28, 2021 Share Posted July 28, 2021 I also have very high TDS (around 350ppm) and I have had no issue with cories. I suspect the other fish could also be acclimated to that TDS, especially the betta, but I can't say so from experience. PH of 9.5 is so high! That's really interesting. I'm surprised your local water supplier allows it to be that high. Link to comment Share on other sites More sharing options...

Kat_Rigel Posted July 28, 2021 Share Posted July 28, 2021 I'd suspect that's true but I don't want to give you the impression that I've done it before with those other species. I bet it can be done. I suspect TDS is less important than clean water and good overall husbandry. Link to comment Share on other sites More sharing options...

Hopefully even less important than ph, gh, kh, etc Link to comment Share on other sites More sharing options...

TDS can be affected by fertilizer, I never worry about TDS but that 9.5, can be a killer and is not good, I'm not sue African cichlids would live long in that Link to comment Share on other sites More sharing options...

I was just illustrating that tap water isn’t an option for me. Link to comment Share on other sites More sharing options...
Mmiller2001 Posted July 28, 2021 Share Posted July 28, 2021 The high TDS is because Equilibrium has potassium and iron included it its mix. If you are looking for lower TDS, switch to diy dry fertilizers. CaSO4 and MgSO4. Link to comment Share on other sites More sharing options...

CA and Mg make up GH. If you want to set a GH while maintaining a lower TDS, you will need to forgo equilibrium, and use as I mentioned. Link to comment Share on other sites More sharing options...
