Hi
I have recently switched to RO. I have a trigon 350 planted community tank as attached pic. CO2 diffuser is inline in my external 407 canister. Also have a protein skimmer at the back.
The issue is that since switching to RO my indicator for CO2 in the tank (I have 2 and repalce the liquid monthly on staggered 2 week rotations using different products for each C02 drop checker) is often yellow, but bubble counter now lot lower than pre RO.
I test RO water. Stand it for 24 hours before adding tropic re mineralised using digital scales to be very accurate and test KH, alkalinity GH, PH after dissolving minerals.
I am worried as my tap water tds is around 300 and RO around 150, is the use of RO destabilising pH and can I rely on drop checkers. I am not keen to add further buffers to the water ideally but concerned that the indicators are not accurately reflecting my CO2. If it stays yellow and wipes my fish I suspect I will go back to Malawis. Starting to miss the simplicity and concerned I have bitten off more than I can manage with this project as despite hours weekly, still having problems
