Hi folks, I took a ph reading now and wow its gone down to 6.4 from about 6.8 (lights still on). I was gonna dose Tetra blackwater tonight but seems like I shouldn't allthough it is not supposed to affect buffering capacity.
This PH drop must have been over the last few hours... (Fish are looking at their best ever, actively searching tank for food and algae)
Should I switch off the lights (what will happen)
Should I disconnect the CO2 (what will happen)
Should I do both (what will happen)
I do not have figures but our water is quite soft (flowing mostly over granite river beds), I do not get any hardwater deposits ever. Comes out of the tap at Ph 7 settles down to 6.8 /6.7 don't know if this tells you anything about my water, but I know there are some guys here who can put the picture together.
Ironicaly now that I need more test kits I'm a bit low on dough, so I'm gonna have to go with your theories and best practices advice.
I'm a good fishkeeper, so I will notice anything wrong with the fish immediatly.
