210 gallon Frontosa build

It took slightly larger pH swings to bother even my wild caught Frontosa so I would think that a change from 8.2 to 7.8 should not cause stress in F1 frontosa. What about your water's GH? I found this to be a crucial parameter for my wild caught Frontosa. Is there a significant change in GH after a water change?

I’ll have to check - it’s always been fairly high and stable, sitting at around 17 degrees. However, I’ve never checked immediately before and after a water change. I’ll do that next week.

I only had a problem with GH when I didn't realize how important it was and varied the epsom salt in my buffer mixture. You probably shouldn't have an issue there.

I’m actually on a well - so it probably changes a bit with the seasons? But no CO2 as far as I know -

It’s actually .4 - 8.2 to 7.8. Would that still be fine in your estimation?

Also thanks!

It's a pleasure to share info & experiences mate!

I wouldn't expect a 0.4 variation to be problematic to be honest. Not as problematic as trying to pH match water out of the well to the tank pH anyway. The nitrogen cycle is a naturally acidifying process so there will almost always be some measure of pH drop from 1 water change to the next.

When I kept discus I would "age" my water 24hrs in a 50gal barrel with an airstone & heater as discus are sensitive to the microbubbles created as municipal water depressurizes, but, with well water, you don't have to worry about that even.
