It might be that unless your LFS is a mom & pop and they keep Discus or other high level fish that require it, that your
LFS has the same water you do, depending on how far away you live from them. If that is true, the fish you get from there
are accustomed to your water already in which case what Hoppy said would likely apply.
Plants grow better in low Ph water and since I have ten G tanks it's easy to just add a measured amount of R/O water
which is $.88 per gallon from Walmart to my water to accomplish this. The tap is 7.8-8.2(I have no high end test kit
so I'm just guessing from the test results/w the low end kit) and is reduced to 6.4-6.6 by adding x amount of the R/O
each time I do a water change. But that's my point, I'm locked into that each week. No problem in a ten G(two of them)
but do you really need to change it ?
P.S. Actually I don't know what the TDS is supposed to be but the "other" things look fine. And a Kh lower than 3 CAN cause problems.
