First post, first question!
After a recent blitz of my 33G I have opted for Co2 injection via a JBL profi 1 set, this was all well and good until I hit a PH crash
In a nutshell I have a Tap reading of PH 7 KH 0 - my tank reads PH 7 KH 3dKH, with the introduction of Co2 I noticed that my PH dropped to 6.4 but the KH stayed stable, by the end of the night my PH had dropped to 6 - still 3dKH
Fish were not best pleased so the spray bar was upturned, Co2 closed down and an air line introduced for overnight bubble fest. This morning all was once again well so air line off, spray bar upturned and Co2 opened up on a slow bubble rate. So far this has given constant readings with my PH remaining stable along with KH [7 & 3dKH] but I would like to up the Co2.
If I open up the Co2 again I preume that my PH levels will drop? Yesterday they went 7 - 6.4 - 6, my fish didn't like PH 6 so whats the best way around this? Is it literally trial and error or is there something that will give a little room for movement?
Also haven't got the Co2 on a Solenoid valve so it's 24/7 - thinking of rigging up a timed air pump for through the night to diffuse the unused Co2
Thanks for any advice sorry if this doesn't string together too well but it's been a long day!
