We contacted the water company today and they refered us to their website. I had already been on it but dont see kh/gh listed. I'm pasting a link, if anyone has time can you see if you can make sense of the info and what i'd need to do to lower my ph?

I've seen that site before, another PN member linked it. Anyway, they give hardness in the chart at mg/liter, and at the bottom they explain that mg/l is equivalent to ppm (parts per million) so that's easy. Your water is in the range of 71 to 206 ppm, which equates to soft to moderately hard. We use dGH for the hardness range in our fish profiles, and you can convert ppm to dGH by dividing by 17.8 or 17.9 (have trouble remembering). I also have a chart I check, and with 70-140 ppm being 4-8 dGH which is considered soft, and 140-210ppm equating to 8-12 dGH which is moderately hard, your water is somewhere in there. They are also correct that calcium and magnesium are the minerals contributing to hardness.

Before going on with this issue, I'll just mention that you also have dissolved heavy metals and sodium in the water. Not particularly high, but of concern. Copper for instance at .25 is high for fish, who need it no higher than .02 but this is not a worry as long as your water conditioner detoxifies heavy metals. Plants can take up heavy metals and detoxify them also, in addition to using some of them (like copper) as a nutrient. But the water conditioner is safer to rely on I think.

Now to the hardness. This level will provide some buffering on the pH, preventing it from fluctuating. Exactly how much I do not know, that is getting beyond my limited chemistry knowledge. As I explained earlier on, over time the natural tendency is for the water to acidify and the pH to lower. I would monitor pH in this aquarium for a few weeks to see how far that goes. The fish you have will probably be fine, but I would not add something as "delicate" [in water parameter terms] as a ray, not yet. Also, wood does help to lower pH, by releasing tannins. I don't believe this is significant, but it clearly does, so having some real wood (and that suits most fish habitats) is another positive.

thank you so much for your assistance and insight byron!! I truely appreciate you taking the time to help me gain an understanding of what's going on. I'll be honest, the mention of ph is beyond my chemistry knowledge - it was the one class i struggled with ever. I am just going to let the tank hang tight for now and see what happens from here. I'd rather have a stable tank with slightly higher that desirable ph than trying to adjust it and have it fluctuate suddenly and lose fish.


Perhaps i'll look into adding some plants soon and hope that helps. I would much rather adjust the ph naturally than add any sort of chemicals to my tank

Plants per say won't have much effect, wood would have more and that is something I definitely recommend with your fish types, present and planned/hoped for. After a few weeks we can review what's happening, and there are safe ways to lower hardness/pH that we can discuss then.

And you're very welcome.

Any suggestions?

The most important thing is for the pH in the tank to be stable, not fluxuate. Fish will acclimate to pHs diverse from what would be natural to them (except of course for some extreme examples like discus in 8 or some such) but wide swings in pH can cause illness and death.

My tap water ph shifts sometimes between 8 & 9 and since I have an oscar I've always used API's Proper pH to keep my tank water a consistent 7.
