Hi everyone,
I'll try to keep this brief as I have already posted this question on another forum with some helpful but limited feedback.
I recently had some fish deaths which I've narrowed down to the difference in pH between my RO/Tap water mix and the lower pH in the tank at around 6.5-7.0 (caused in part by my CO2 injection and the substrate/wood/almond leaves)
I do a 50-60% water chance once a week with a 50/50 Tap/RO mix and so far my pH readings for this have been very high at around 7.7. It was suggested to me that I up the ratio of RO/Tap to 70/30 to lower the KH but this has resulted in an even higher pH of 8.7.
Ive tried aeration and the addition of almond leaves to the barrel of water and if anything this has only increased the pH. Im using an electric pH pen to take readings but have also used liquid test kits (new).
If anyone has any suggestions then Id love to hear them, im very far behind on my water change but still would rather have high nitrates instead of shocking the fish with a big pH swing and risk more deaths.
I dont want to flood this initial post with too much info but please let me know if there's any other info about the tank that I should provide.
Many Thanks
Keith
