Thank you!Just read the entire thread. I was particularly interested, in the beginning, in your efforts to consistently keep your PH so low.
Takes a lot of effort to maintain a tank the way you have this one. Well done.
This low tds high tannin environment is perfect. PH would be less of a concern as long as it remains fairly below 7. I think you're overthinking your PH tool.
You shouldn't need to keep the pH specifically in the 5s as long as the water is soft and clean. Peathenster bred them with his pH in the 6s. Just keep it on the acidic side, under 7, and they'll probably be alright.
Part of why I'm tweaking the ph is because the tank was stable at 5.2 for so long. I know it can be done. It one of those nagging things that I can't seem to let go.
You've started dosing with seachem equilibrium and added rooibos tea recently? I wonder if they've been doing well in pure RO water? Mind sharing how this product has effected your water parameters? Mostly curious if it increases TDS.
They had been doing fine in pure ro water. What had happened was, my source for ro water had good stable chemistry. Tds in the low 20's, a small amount of CCaO2, etc, and everything was good. Unbeknownst to me, my source changed out their filters, which caused the ph crash, and now the tds is 2-3. That's why we started dosing equilibrium. It raises ph a bit, probably wouldn't even notice it in a normal tank, it also increases tds. We're using enough to put tds at around 30 before HCL addition. After HCL, tds is around 45.
