I have 20lbs Amazonia which is about a month old and I know that buffers ph down, I have a few pieces of driftwood, and am running diy CO2 until I can get a tank for my new regulator. I'm aware all of these things lower the pH of the water but that much?
Basically my question is this. Would switching to all RO water make a difference? I really don't want to use chemical buffers to mess with my waters. I know I'm gonna have to add GH booster but don't mind that. I can experiment with doing a mix of RO and tap, but I'd rather just do one or the other if I can get away with it. Am I over reacting and being paranoid or do I need to give it more time?
Your well water parameters are very similar to ours. I have been keeping fish for quite some time. Suddenly, one day one of my fish was acting ill. I tested everything and it was 0 (everything meaning nitrates, nitrites and ammonia) and I was confused. Finally a friend did a quick test that included PH and I never thought to test PH because it always tests the same.
My PH went down from 8.5 to TWO!!!! No wonder the poor fish were sick. So, I did a gradual tank change (repeated water changes incrementally over a 24 hour period) and he was doing better. Nothing else changed, and I did not have any additives in there, nothing.
Within a week it was back at 2 again.
So, after I changed out everything but the filter contents (I knew it wasn't that) , I finally decided to change out the NATURAL gravel I had put in some time back.
The PH went back up to 8.5ish and varies from 8.2-8.5 ever since.
It makes no sense. Rocks usually take PH HIGHER not lower. But those rocks were the culprit and I never had a similar experience before or after with any other tank and I have on average six at any given time.
